Selenium helps reduce bladder cancer risk

New York: Increasing selenium levels may help to significantly reduce a woman’s risk of developing bladder cancer, according to new research from the American Association for Cancer Research

Researchers measured selenium levels in the toenails of 767 people with bladder cancer and 1,108 people without the disease. Whilst no link was found between selenium levels and bladder cancer risk for the population as a whole, the mineral did significantly reduce the risk of bladder cancer in certain groups of people – women, moderate smokers, and those with p53 positive cancer.

Lead researcher Margaret Karagas said: “Ultimately, if it is true that selenium can prevent a certain subset of individuals, like women, from developing bladder cancer, or prevent certain types of tumors, such as those evolving through the p53 pathway, from developing, it gives us clues about how the tumors could be prevented in the future and potentially lead to chemopreventive efforts.”

Early detection reduces oral cancer deaths – new study

image

London: EXPERT studies have warned that late detection of mouth cancer is causing unnecessary deaths, backing the UK’s leading oral health charity’s Mouth Cancer Action Week 2008 campaign message.

A Journal of Prosthodontics study has called on greater emphasis on oral cancer screening. Early detection of oral cancer leads to a 95 per cent survival rate – yet currently the majority of cases are picked up late – with less than half surviving beyond five years.

The British Dental Health Foundation led the November’s Mouth Cancer Action Week with the call ‘If in doubt, get checked out.’

Foundation chief executive Dr Nigel Carter BDS LDS (RCS) said: “The majority of oral cancers are diagnosed at a late stage – which means so many deaths are unnecessary. Mouth cancer is often painless, this hidden killer causes a death every five hours in the UK.

“The public and the profession must all work together to make sure were stay aware of the dangers. Dentists and hygienists must communicate with their patients on this issue; while it is vital people visit their dentist regularly.”

Researchers at the Journal of Prosthodontics called for greater commitment from dentists to looking for mouth cancer: “If dentists are more vigilant in performing oral cancer screening examinations on all of their patients, the quality of life and survivability from these cancers will be greatly improved, whereby morbidity and mortality will be greatly reduced.”

The study urged use of screening aids to boost detection, and showed that the need for regular screenings had risen, as attempts to educate on prevention had stalled.

Nearly 5,000 people are diagnosed with oral cancer each year in the UK, with tobacco and alcohol related to around three quarters of all cases.

An ageing population puts more at risk in the most common over 40s age group, while increasing numbers of young are affected – a quarter of cases displaying no risk factors.

The human papilloma virus, transmitted through oral sex, has also been linked to rising numbers of mouth cancer incidences.

The Foundation’s 2008 mouth cancer survey showed one in five UK patients remain unaware of mouth cancer. Seventy per cent of patients said they had not discussed the disease with their dentist, and were not sure they had ever received oral screening.

Mouth Cancer Action Week 2008 was launched at the Houses of Parliament in November 2008, with a speech by leading expert Professor Saman Warnakulasuriya calling for government support for dentists giving oral screening.

The campaign highlighted a need for the public to self examine, looking out for ulcers that do not heal within three weeks, red and white patches in the mouth, and lumps, swelling or unusual changes in the mouth and neck.

Facts and Figures

In the UK over 4,750 are diagnosed each year.

Around 1,700 people die of mouth cancer every year.

Mouth cancer is more common in men than women, but the gap is closing

Mouth cancer is more likely to affect people over 40 years of age, though an
increasing number of young people are developing the condition.

Tobacco and alcohol are thought to contribute to 80 per cent of mouth cancer cases.

Smoking is the number one cause for mouth cancer. Cigarette smoke converts saliva into a deadly cell-damaging cocktail.

Switching to low-tar cigarettes will not help, as smokers of ‘lights’ tend to inhale more smoke than smokers of ‘regular’ cigarettes.

Although some people believe that chewing tobacco is safer than smoking, the reality is that it is even more dangerous. Chewing tobacco, paan, areca nut and gutkha are habits favoured by some ethnic groups.

Alcohol aids absorption of smoke into the mouth – people who smoke and drink alcohol to excess are 30 times more likely to develop mouth cancer.

Poor diet is linked to a third of all cancer cases. Evidence shows an increase in fruit and vegetables lowers the risk, as can fish and eggs.It is recommended that people enjoy a healthy, balanced diet, including food from each of the major food groups and including fruit and vegetables of all different colours as each colour contains different vitamins

Research now suggests the human papilloma virus (HPV) – transmitted by oral sex – could soon rival smoking and drinking as a main cause of mouth cancer.

Early detection and treatment considerably increases survival chances, allows for simpler treatment and results in a better quality of life for sufferers

Cancer

The risk of developing most types of cancer increases with age.

In women, the rate of cervical cancer decreases, and endometrial cancer increases so it’s important for women to get regular exams.

The risk of prostate cancer increases with age, and black men have a higher rate than white men. Screening should start in your 40s, and at the very least should involve a digital rectal examination.

Lung cancer accounts for more deaths than breast cancer, prostate cancer, and colon cancer combined. So stop smoking.

Scientists in prostate cancer breakthrough

London: British scientists have created a new drug that can shrink prostate tumours in 80 per cent of cases, it was revealed today.

The drug, called abiraterone, was discovered by doctors at London’s Royal Marsden Hospita.

Prostate cancer,is a disease that is more prevelant over the age of 50,and as people live longer, the incidence is expected to increase.

There are two types of prostate cancer: aggressive and non-aggressive. In the latter, which accounts for about a third of all prostate cases, the disease is usually fatal within 18 months.

The disease can be treated using hormone therapy which blocks testosterone but in many cases the cancer becomes resistant and the only other alternative is chemotherapy which has many unpleasant side effects.These include nausea, pain and hairloss.

Royal Marsden lead researcher Dr Johann de Bono said the new drug required the patient to take just four pills a day.

It is hoped that the drug will be on sale for general use by 2011.

Scientists believe the technique could also be effective on other tumours, such as breast and bowel cancers.

Abiraterone works by blocking a key enzyme in the body which help in the production of the male hormones.

Patient trials at the Royal Marsden, home to Britain’s Institute of Cancer Research and Europe’s largest cancer research centre, which eventually came up with abiraterone revealed that it shrank the tumour in three quarters of patients.

Abiraterone is now being used in a 1,200-patient international study, including at ten sites across the UK. If it is licensed as expected in 2011.

Melanoma

A dangerous form of skin cancer which can be deadly

Anne Robinson reveals how her skin cancer scare made her sun savvy

image

London: New statistics show that skin cancer is now the fastest growing cancer in the UK, and as early detection is crucial in its treatment, the British Association of Dermatologists (BAD) is launching a campaign to raise awareness of the importance of mole checking through its ABCD-Easy guide to mole checks.

Malignant melanoma kills around two thousand people a year, and the Association is keen to promote the use of its easy to use mole check guidelines. TV favourite Anne Robinson is supporting the campaign and turning her no-nonsense approach to the nation’s skin.

She said: “I doubt I would be here today if a dermatologist hadn’t spotted that the mole in the middle of my back looked dangerous. It wasn’t visible to me. It took two operations to clear my melanoma; the result of years of sunbathing when I was young without bothering too much about protection -or realizing the risk to someone as fair skinned as I am. I’m lucky to be alive.”

Anne’s case highlights the importance of checking you skin for signs of cancer, and the Association’s ABCD-Easy guide to mole checks focuses on the changes that may indicate a “melanoma” – the deadliest form of skin cancer:

Asymmetry – the two halves of the area may differ in shape

Border – the edges of the area may be irregular or blurred, and sometimes show notches

Colour – this may be uneven. Different shades of black, brown and pink may be seen

Diameter – most melanomas are at least 6mm in diameter. Report any change in size or shape to your doctor

Expert – if in doubt, check it out! If your GP is concerned about your skin, make sure you see a Consultant Dermatologist, the most expert person to diagnose a skin cancer. Your GP can refer you via the National Health Service.

Nina Goa d of the British Association of Dermatologists said: “Early detection of skin cancer can make all the difference to successful treatment and by promoting how easy skin checking can be, literally as easy as ABC, we want to encourage more people to make it part of their health routine.”

Dermatologists are the experts in diagnosing and treating skin cancer, and BAD recommends reporting any unusual changes in your skin (not only those in its ABCDE guide) to your doctor so that a referral can be made.

The vast majority of skin cancers are caused by excess exposure to the sun. In fact, more than four out of five cases of skin cancer are thought to be preventable. Simply being more aware of the general health of your skin and checking moles regularly – at least four times a year – could make all the difference.

High GI foods linked to lifestyle diseases

image

Sydney: Scientists in Australia have found conclusive evidence that a high GI diet, generally rich in food that is burnt by the body quickly, leads to a higher risk of common lifestyle diseases.

The Glycemic Index (GI) is a measure of how different foods affect your blood glucose levels, with those that are “low GI” released more slowly and deemed better for health. This slow release means that less insulin is released into the bloodstream and the body’s stores less fat.

A team of nutrition experts at the University of Sydney evaluated 37 diet studies involving nearly two million people worldwide to analyse the effect of eating high GI foods, which are usually highly processed.

The study, published in the American Journal of Clinical Nutrition, found a link between a high GI diet and a high risk of type 2 diabetes and heart disease.The diet was also linked to gall stones and some types of cancer.

Lead researcher, Alan Barclay said: “The key message from this study is that the GI of your diet is a powerful predictor of disease risk.Grandma was right, you are what you eat.”

He said the link with diabetes was “not surprising” because eating high GI foods inflates your blood glucose and insulin levels.

“You may literally ‘wear out’ your pancreas over time and eventually it may lead to type 2 diabetes in older age,” Mr Barclay said.

The researchers were more surprised by the “strong relationship” between GI and cancer.

High GI foods cause constant spikes in blood glucose which increase insulin and a related substance called ‘insulin-like growth factor one’, both of which have been shown to increase the risk of developing cancer.

“Other research shows that a high GI diet tends to reduce ‘good’ HDL cholesterol levels and raise triglycerides levels; bad news for cardiovascular diseases,” he said.

“And people with low HDL cholesterol and high triglyceride levels are more prone to gall stones.”

The researchers said their findings support eating a low GI diet to maintain healthy weight and help avoid disease.

Caryl Nowson, a professor of nutrition and ageing at Deakin University in Melbourne, said because high GI foods were typically high in fat and sugar and low in fibre, they were also ready known to be linked with disease.

“This review is just a new way of breaking down dietary information we already have,” Prof Nowson said.

She said while the benefits of eating according to GI rating had been proven, it was just one of many ways to structure a healthy diet.

“If you focus on having a classically balanced diet high in fibre and low in sugar, fat and refined foods you’ll find you’re eating relatively low GI anyway,” Prof Nowson said.

Longevity affect of selenium limited

image

New York: The health protection of the mineral selenium are associated only with moderate levels of the supplement, a new report has found.

While moderate levels of the mineral are associated with longevity, once selenium levels climb past a certain mark, the odds of dying from any cause, or from cancer specifically, begin to tip upward, a new study suggests.

The study, of nearly 14,000 US adults, found that higher blood levels of selenium were linked to a lower risk of death over 12 years, at which point the risk appears to increase.

The findings, published in the Archives of Internal Medicine, support earlier studies linking selenium to lower risks of prostate, lung and colon cancers. But the study also “raises the concern that high-normal levels of selenium may be associated with an increased risk of mortality,” write the researchers, led by Dr. Joachim Bleys of Johns Hopkins University School of Public Health in Baltimore.

Selenium is a mineral that people require in small amounts; food sources include grains, certain nuts and some meats and seafood, such as beef and tuna.

The body incorporates selenium into proteins called selenoproteins, which act as antioxidant enzymes; antioxidants, in turn, help neutralize cell-damaging substances called free radicals. Some studies have linked higher selenium levels to lower risks of certain cancers and heart disease.

However, much of the research has been done in countries where people’s selenium levels are often fairly low.

Most Americans do get more than the recommended amount of selenium. While the recommended dietary allowance (RDA) is only 55 micrograms per day, the typical intake in the from 60 to 220 micrograms daily. They found that as the participants in the study whose blood levels of selenium increased, their odds of dying during the 12-year study period declined.

But once blood levels of selenium surpassed 130 ng/mL, the benefits stopped accruing; and once they passed 150 ng/mL, the odds of dying from any cause, or from cancer in particular, began to creep back up.

The findings caution against consuming too much selenium, according to the researchers.
It is not clear why high-normal selenium levels were tied to an increased death risk. But in theory, Bleys explained, excess selenium that is not incorporated into selenoproteins may actually generate free radicals rather than fight them.

Scientists discover new prostate cancer biomarkers

image

London: Uk scientists have identified seven pieces of “rogue DNA” which could put men at increased risk of prostate cancer.

Theese genetic flaws are so common that it is thought every man has at least one.

Currently men are screened for higher than normal levels of a protein known as Prostate Specific Androgen (PSA) but the results are not always accurate.

The British researchers, whose work was funded by Cancer Research UK, are developing a genetic test , which will look for 12 flaws, but it may be more than three years before it is publically available. Lead researcher Dr Ros Eeles, of the Institute of Cancer Research in London,said the team’s discovery of the seven pieces of rogue DNA – the most prostate cancer ‘hotspots’ identified in a single study – could lead to the development of new drugs.

‘These exciting results will help us to more accurately calculate the of developing prostate cancer and may lead to the development of better targeted screening and treatment,’ she said.

Cigarette poison kills anti-ageing gene, new research reveals

image

New York: Scientists have discovered one of the ways in which smoking cigarettes makes you age faster and puts you at risk of diseases such as chronic obstructive pulmonary disease (COPD) and lung cancer.

Researchers at the University of Rochester in the US found that the toxins in cigarette smoke wipe out a gene that protects the body against premature ageing.

Dr Irfan Rahman, associate professor of environmental medicine and an investigator in the University of Rochester’s Lung Biology and Disease Programme, noted: “You can be 45 years old and look great on the outside, but if you are a smoker or former smoker, your lungs can easily be 60 years old because of the chemical assault.”

Cigarettes contain around 4,700 toxic chemical compounds which decrease the lungs’ production of SIRT1, a protein that helps to regulate chronic inflammation, cancer and ageing.

The University of Rochester team, in collaboration with Finland’s Helsinki University Hospital, confirmed that levels of SIRT1 are significantly lower in smokers than in non-smokers.

This in turn affects genes that help to detoxify the airways, speeding up the ageing process of the lungs.

The findings are published in the American Journal of Respiratory Critical Care Medicine and in the American Journal of Physiology.

Cryo-surgery that removes breast tumours in minutes

image

London: Breakthrough ice technology developed by a British company means that many thousands of women with non-cancerous breast tumours can now be successfully treated in their doctors surgery rather than having to endure a hospital operation.

The treatment, developed by technology and product development company, Cambridge Design Partnership (CDP) and its client Sanarus Medical Inc based in California involves inserting a thin probe into the breast tumour which is then frozen at temperatures of -20 to -40 degrees centigrade.

The frozen tumour dies and over time is reabsorbed by the body.

Ultra sound is used to ‘image’ the growth of the ice ball during the freezing process making sure that only the affected tissues are frozen.

The treatment is quick, painless and takes less than 30 minutes to treat a large tumour of perhaps 4cm, while most take less than 15 minutes.

Prior to the development, GPs were reluctant to become involved in cryo-surgery because the equipment needed was bulky, cumbersome, difficult to use and intimidating for the patient. Also the main gas involved, argon, is difficult to obtain and is contained in large torpedo like tubes which weigh around 75 kilos each and need securing to a wall.

The main alternative for GPs was to recommend surgery with all its associated emotional trauma. Plus, the surgery would leave scarring and the ‘void’ left by removing the tumour could disfigure the shape of the breast. Additionally, there are always risks attached to a general anaesthetic as well as the possibility of infection, and patients can also expect a 2-3 day recovery period.

The technique developed by CDP and Sanarus, replaces argon with liquid nitrogen which is stored in 1 litre flasks. This breakthrough opened up the possibility to create a small, portable unit, called Visica 2, which is much easier to use, is not intimidating and more ‘user friendly’ for both the GP and the patient.

The procedure requires a tiny 3mm incision in the breast which is then covered by a normal plaster and no stitches are necessary.

Dr Keith Turner from Cambridge Design Partnership who led the UK team
commented: “This breakthrough means that a woman diagnosed with a non-cancerous breast tumour can pop into her doctor’s surgery, receive treatment and then get on with her day – in less time than it takes to do the weekly shop.”

The most common cause of benign breast lumps is the over development of fibrous tissue called fibro adenoma which, if it continues to grow, can become uncomfortable. Many women opt for surgical removal because they find the tumours emotionally and physically unacceptable.

Rather than an operating theatre, surgeons, anaesthetist, recovery nurses, physical scarring and emotional trauma, the new procedure is reduced to a doctor’s surgery, excellent cosmetic results and a dramatically reduced treatment time.

Millions die of cancer around the globe – latest statistics

image

New York: Cancer deaths continue to increase, with the American Cancer Society reporting 12 million new cases of malignancy diagnosed worldwide in 2007, with 7.6 million people dying from the disease.

The report, Global Cancer Facts & Figures, finds that 5.4 million of those cancers and 2.9 million deaths are in more affluent, developed nations, while 6.7 million new cancer cases and 4.7 million deaths hit people in developing countries.

“The point of the report is to promote cancer control worldwide, and increase awareness worldwide,” said report co-author Dr. Ahmedin Jemal, director of the society’s Cancer Occurrence Office.

The number of cancers and cancer deaths around the world is on the rise, Jemal said, mostly due to an aging population. “There is increasing life expectancy, and cancer occurs more frequently in older age groups,” he noted.

Lifestyle may be another reason for the rise in malignancies in developing countries, Jemal said, as people adopt Western behaviors such as smoking, high-fat diets and less physical activity.

The best way to stem the increasing number of cancer cases and deaths is prevention, especially in poorer countries, the expert said. In many developing nations, the health-care infrastructure simply isn’t there to offer cancer screening and treatment for most people, Jemal added.

In developed countries, the most common cancers among men are prostate, lung and colorectal cancer. Among women, the most common cancers are breast, colorectal and lung cancer, according to the report.

However, in developing countries the three most common cancers among men are lung, stomach and liver, and among women, breast, cervix uteri and stomach.

Worldwide, some 15 percent of all cancers are thought to be related to infections, including hepatitis (liver cancer) and human papilloma virus (cervical cancer). But the incidence of infection-related cancers remains three times higher in developing countries compared with developed countries (26 percent vs. 8 percent), according to the report.

In addition, cancer survival rates in many developing countries are far below those in developed countries. This is mostly due to the lack of early detection and treatment services. For example, in North America five-year childhood cancer survival rates are about 75 percent compared with three-year survival rates of 48 percent to 62 percent in Central America, the report notes. The report estimates that 60 percent of the world’s children who develop cancer have little or no access to treatment.

The report also includes a section on the toll tobacco use takes around the world. In 2000, some 5 million people worldwide died from tobacco use. Of these, about 30 percent (1.42 million) died from cancer — 850,000 from lung cancer alone.

Jemal believes smoking is a key culprit.

“Smoking prevalence is decreasing in developed countries. So, as tobacco companies are losing market in developed countries they are trying to expand their market in developing countries,” he said.

In China alone, more than 350 million people smoke. “That’s more than the entire population of the United States,” Jemal said. “If these current patterns continue, there will be 2 billion smokers worldwide by the year 2030, half of whom will die of smoking-related diseases if they do not quit,” he added.

In the 20th century, tobacco use caused about 100 million deaths around the world. In this century, that figure is expected to rise to over 1 billion people. Most of these will occur in developing countries.

One expert agreed that many cancer deaths can be avoided through lifestyle changes.

“What is most provocative here is not the total global burden of suffering and death cancer causes, dramatic though that may be, but the variations in cancer occurrence around the world, and the insights provided about how much of the cancer burden need not occur at all,” said Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine.

In developing countries, cancer of the uterine cervix is a leading cause of death in women, Katz noted.

“Yet this infection-related cancer is now preventable by vaccine, and long treatable when detected early using the Pap smear. As a result, death from cervical cancer in developed countries is dramatically lower. Its toll in the developing world is testimony to missed opportunities to apply our resources effectively, and equitably,” he said.

Cancer of the liver, often related to hepatitis infection, is a leading cause of death in developing countries, but not so in developed countries. “Again, an infection preventable with vaccine is causing death because of inequities in the distribution and use of existing resources,” Katz said.

Prostate and colon cancers are more common in wealthier countries, where they are likely related to poor diet and obesity, Katz said. “Unnecessary suffering and death are occurring in affluent countries due to dietary excesses,” he said.

Katz also noted that tobacco-related cancer is largely preventable. “The toll of tobacco-related disease, including lung cancer, is an appalling example of a global willingness to tolerate preventable suffering and death for the sake of profit,” he said.

These data show both developed and developing countries how to move toward the lower rates of specific cancers, Katz said.

“It will be a tragic failure for public health if instead of applying these lessons developed countries continue to export tobacco and dietary transgressions so that the developing world adds to its current cancer burden ours as well,” he said.

Are you getting enough Vitamin D?

image

As a lack of vitamin D is linked to various diseases including the return of rickets, cancer, heart disease, tuberculosis and diabetes.

Since it is produced in the skin on exposure to sunlight, those living in Scotland and the North of England are more likely to suffer deficiency.

Experts recommend between five and 25 micrograms per day, however, 90 per cent of adults in the UK make less than three.

The situation is worst for those north of Birmingham where the sun is too weak in winter for the vitamin to be produced.

A recent report in the US journal Proceedings of the National Academy of Sciences revealed that people with higher levels were more likely to survive colon, breast and lung cancer. This follows last year’s University of San Diego review of 40 years of research, which revealed that a daily dose could halve the risk of breast and bowel cancer.

Other claims are that it reduces the risk of heart disease (a study of 10,000 women in California found that those who took supplements had a 31 per cent lower risk of dying from it), diabetes (in a Finnish study of 12,000 children, it cut their chance of developing Type A diabetes by 80 per cent), even colds and flu (New Yorkers who took vitamin D had flu 70 per cent less often).

Yet despite this increasingly compelling evidence, too many of us are not getting enough. The result: a resurgence in rickets, which stunts growth and deforms the skeleton, causing bowed legs.

Vitamin D Fact File

• 90 per cent of the body’s supply of vitamin D is generated by reaction to sunlight on the skin.

• Vitamin D is found in oily fish like sardines, salmon, mackerel and tuna, cod liver oil, and in milk, cheese, eggs and liver.

• “Healthy Start” supplements for children up to the age of four are given free to those on benefits but can also be bought for £1.70 at pharmacies or health clinics.

• The first mention of rickets is credited to Daniel Whistler, an English doctor who wrote a paper in 1645 on the subject.

• Vitamin D was named in 1922 by the American biochemist Elmer McCollum, who performed experiments to find the nutrients within cod liver oil. It was so called because it was the fourth substance he identified.

• One in 100 children from ethnic minorities in this country is thought to be deficient in vitamin D; darker skin requires more sun to produce the vitamin.

• In 2003 a New York couple were convicted of endangering the life of their 15-month-old baby after subjecting her to a strict vegan diet which left her suffering from rickets. Silva and Joseph Swinton were sentenced to six and five years in jail.

• The classic signs of rickets are bow legs caused by softening of the bones; if not detected early surgery is needed to correct it.

• Most people can make enough vitamin D in the summer to last them through the winter

Support Prostate Cancer Awareness Week

Prostate cancer is now the most common cancer diagnosed in men in the UK – every hour at least one man dies from this disease.

It is a cause that has suffered from years of neglect, so plan NOW for Prostate Cancer Awareness Week, 10-16 March 2008 – it’s your chance to make a difference.

Prostate Cancer Awareness Week 2008 aims to raise the profile of prostate cancer among the public and in the media. Hundreds of individuals and groups across the UK will join forces to help raise awareness of prostate cancer and raise vital funds to improve research, information and support services for men and their families who are affected by this disease

An early diagnosis of prostate cancer could improve a man’s chances of finding a successful treatment, yet 90% of adults in the UK do not know what the prostate gland does and the crucial role it plays in a man’s sexual function.

About Prostate Cancer Awareness Week

Prostate Cancer Awareness Week is an annual health awareness campaign organised by The Prostate Cancer Charity.

Every year nearly 35,000 men are diagnosed with prostate cancer in the United Kingdom and 10,000 men die from it.

African Caribbean men are three times more likely to be diagnosed with prostate cancer than their white counterparts.

The Prostate Cancer Charity is striving for a world where lives are no longer limited by prostate cancer. The Charity is fighting prostate cancer on every front – through research, support, information and campaigning.

If you have any queries about prostate cancer call The Prostate Cancer Charity’s confidential helpline 0800 074 8383 which is staffed by specialist nurses and open from 10am to 4pm Monday to Friday and Wednesdays from 7 – 9pm.

Blood test for breast cancer only months away

image

Oslo: A Norwegian company has developed a blood test for breast cancer which could be on the market in a few months.

The life sciences company DiaGenic ASA is hoping to get Europe-wide approval by the end of next year.

The test uses a technique called ‘gene expression analysis’ to find a signature or pattern that distinguishes healthy blood from diseased blood or tissue. It can detect early tumors.

In the UK private healthcare provider Opaldia will offer it to private patients, while NHS patients may benefit if doctors believe it has advantages over existing screening methods and is costeffective.

Currently mammograms are mostly used for women at high risk of breast cancer in their 40s. But these can detect lumps only when they reached a size of between 5mm (0.19in) and 10mm (0.39in), and the density of breast tissue in younger women often makes it difficult to interpret the X-rays.

Low carbohydrate diet may slow prostate cancer

image

New York: A low-carbohydrate diet may help slow the growth of prostate tumours, according to researchers at Duke University.

They have discovered that a diet low in carbohydrates facilitates a reduction in insulin production which stalls prostate tumour growth, according to a report in Science Daily.

Lead researcher and urologist, Dr Stephen Freedland of the Duke University Medical Centre said: “This study showed that cutting carbohydrates may slow tumour growth.”

The research, on rodents, compared prostate tumour growth in 75 animals that were eating either a low-carbohydrate diet, a low-fat but high-carbohydrate diet, or a Western diet which is high in fat and carbohydrates.

They found that those ate a low-carbohydrate diet had the longest survival and smallest tumour size — the findings have been published in the ‘Prostate’ journal.

According to Dr Freedland, “Low-fat mice had shorter survival and larger tumours while mice on the Western diet had the worst survival and biggest tumours.

“In addition, though both the low-carb and low-fat mice had lower levels of insulin, only the low-carb mice had lower levels of the form of insulin-like growth factor capable of stimulating tumour growth.

“The low-carbohydrate diet definitely had the most significant effect on tumour growth and survival.”

Dr Freedland and his fellow researchers are now planning to test the findings of this study in humans. “If this is ultimately confirmed in human clinical trials, it has huge implications for prostate cancer therapy through something that all of us can control, our diets.”

Mouth cancer moves up the death league table

London: Cancer of the mouth is on the increase as a result of poor oral hygiene, according to the latest statistics issued during Mouth Cancer Awareness Week.

More than 1700 people die of mouth cancer in the UK each year – obviously the figure worldwide is far larger.

Dentyl pH®, the mouthwash experts, are providing an education grant to support this year’s British Dental Health Foundation’s – Mouth Cancer Awareness Week – 11-17th November 2007. On average mouth cancer now kills one sufferer every five hours, making it one of the fastest growing cancers.

Commenting on the need to raise awareness among the public and professionals of this little-known disease, mouth cancer, Professor Robin Seymour of Newcastle Dental School and spokesperson for Dentyl pH said: “In the UK, more than 4,750 new cases of oral cancer are diagnosed and 1,700 patients die of this cancer every year. Tobacco smoking and excessive alcohol consumption are the main risk factors for the development of oral cancer. Frequently these two risk factors act together.”

“Oral cancer often arises as an ulcer in any part of the mouth, with the tongue and floor of mouth being the common sites. The ulcer is often painless, although it can bleed, but most importantly it does not show signs of healing over two to three weeks. Some oral cancers also develop in white or red patches. Such patches are termed precancerous lesions, and if present they should be closely monitored for any change in size or colour.”

In summary Professor Seymour notes: “Regular dental checkups and good dental care are important factors in recognising and preventing oral cancer. Dentists, hygienists and therapists are used to examining the mouth and associated structures, and hence can recognise any abnormality. All suspicious lesions should be referred for further investigations. Patients at high risk from oral cancer, such as heavy smokers and drinkers, should always be carefully examined for, and questioned about, any lesion that may be recognised as precancerous or potentially malignant.”

This is the first year that Dentyl pH has sponsored the annual Mouth Cancer Awareness Week campaign. Dentyl pH was created as an alcohol-free mouthwash by people who care about mouths; that is, by dentists themselves. As a result, it’s very appropriate that Dentyl pH should be part of a campaign that encourages people to be more aware of their dental health. Mouth cancer is avoidable and early detection can massively increase the chances of survival.

The Dentyl pH is a clinically proven, alcohol free mouthwash. Using groundbreaking technology, Dentyl pH works like no other mouthwash. This is because it is a two-phase mouthwash, which has to be shaken before use. This action causes the essential oils and the antibacterial water phases to mix, creating a special solution, which makes the ‘bad’ bacteria and food debris adhere to the mouthwash solution. As a result, when the mouthwash is expelled from the mouth, bacteria, debris and other dental deposits are all visible in the sink, proving that Dentyl pH really works.

Mouth hygiene horror facts:

In the UK we still fail to take good care of our teeth and mouths. A recent Adult Dental Health Survey found that:

* only three-quarters of adults (75%) claim to brush their teeth twice a day as recommended

* the average time spent brushing teeth is 46 seconds, far short of the recommended two minutes

* only 2-10% of people floss regularly

* around half of British adults have plaque-related periodontal disease (gum disease)

* more than half of all teenagers and three out of four adults over the age of 35 suffer from gum disease.

Bacterial plaque plays an essential causative role in gum disease, yet it can be removed easily from the teeth by brushing the teeth for two minutes, twice a day, followed by rinsing with a proven mouthwash such as Dentyl pH. Flossing is recommended once a day between brushing and rinsing.

Stress increases breast cancer risk

Stockholm: Stress at work can increase the risk of women developing breast cancer by upto a third, a new study of Swedish women suggests.

It is thought the increased risk is a result of poor lifestyle choices which lead to obesity, increased alcohol consumption, leading to a weakened immune system.

The study published in the journal of Epidemology found that women in demanding jobs are 30 per cent more likely to develop the disease than those who feel on top of their work.

The results of the study, which involved 36,000 women, appear to contradict previous research which has not found a link between stress and breast cancer.

Thousands of women die each year from the disease and although survival rates are improving, the number contracting it is on the increase.

The study looked at information on 36,000 Swedish women aged 30 to 50 who were in work when the study started in 1990. The study followed the women until 2004, by which time 767 of them had been diagnosed-with breast cancer. The risk of breast cancer increased by around 30 per cent for women with stressful jobs after other factors, such as alcohol consumption, number of children, weight, and age, were taken into account.

The Swedish researchers found no link between stress and cancer among women in part-time work.

The reason why stress might increase the risk is unclear, although studies show it may raise levels of the hormone oestrogen which can heighten the risk of cancer. Another theory is that stress changes women’s behaviour, making them adopt unhealthy habits such as smoking and not exercising.

Recent research has found that long working hours and stress from work can bring on the menopause early and, in pregnant women, increase the risk of a miscarriage.

However, a Danish study of 7,000 women over 18 years found those with high levels of stress were less likely to develop breast cancer than women with low stress levels. Leading-cancer scientists yesterday said more research is needed before stress can join other well-known risk factors.

Stem cells found in male testicles

New York: United States researchers have come up with a novel use for men’s testicles, which they say are a rich source of stem cells and so could be transformed into a wide range of tissue types to help fight disease.

The scientists say they have managed to isolate stem cells from the testes of male
mice, extract them and reprogram them into blood vessels, heart cells and tissue.

If the results are reproduced in humans, the technology could help get around the ethical concerns associated with the use of embryonic stem cells and could be used to help treat Parkinson’s, heart disease, strokes and cancer.

Shahin Rafii from Weill Cornell Medical College in New York whose research has been pubished in the journal Nature said: “Testes are designed to generate a lot of sperm and they have these germ cells.

“So germ cells are designed also in a way to give us two different tissues as well so we were able to get a germ cell from testes and instruct them to become other tissues.”

So it is a possible breakthrough, albeit somewhere down the track, for men. But Dr Rafii says women need not give up hope.

“In women also this stem cell exists but the number is very, very low and we hope that eventually we can be able to get these stem cells from their ovaries as well,” he said.

“Also another point – some men can give stem cells to compatible, genetically compatible females so it still can be applied for women as well.”

Cancer cure jab two years away

Cambridge: Some humans have cancer fighting cells which may be used to fight the disease in others.

Dr Zheng Cui, of the Wake Forest University School of Medicine, whose work has been published in the latest issue of the New Scientist magazine, has shown in laboratory experiments that immune cells from some people can be almost 50 times more effective in fighting cancer than in others.

Dr Cui has previously shown cells from mice found to be immune to cancer can be used to cure ordinary mice with tumours.

These cancer-killing immune system cells are called granulocytes which could be made available from donors to significantly boost a cancer patient’s ability to fight their disease, and potentially cure them.

In the US, the Food and Drug Administration (FDA) last week gave Dr Cui permission to inject super-strength granulocytes into 22 patients.

He said: “Our hope is that this could be a cure. Our pre-clinical tests have been exceptionally successful.If this is half as effective in humans as it is in mice it could be that half of patients could be cured or at least given one to two years extra of high quality life.The technology needed to do this already exists, so if it works in humans we could save a lot of lives, and we could be doing so within two years.”

Dr Cui believes patients could benefit from the technique quickly because the technology used to extract granulocytes is the same as that already used by hospitals to obtain other blood components such as plasma or platelets.

Prof Gribben, a cancer immunologist at Cancer Research UK’s experimental centre at St Bartholomew’s Hospital, London, said: “The concept of using immune system cells to kill off someone else’s cancer is very, very exciting.”

Dr Cui, who presented his latest findings at an anti-ageing conference in Cambridge last week, extracted granulocytes from 100 people, including some with cancer.

When the immune cells were mixed with cervical cancer cells, those from different individuals demonstrated vastly varying abilities to fight the cancer.

Those of the strongest participants killed close to 97 per cent of the cancer cells in 24 hours, while those of the weakest killed only two per cent.

The abilities of the cells of participants aged over 50 were lower than average, and those of cancer patients even lower.

Dr Cui noticed that the strength of a person’s immune system to combat cancer can also vary according to how stressed they are and the time of year.

Initial experiments suggest it may be possible to transfer granulocytes which have demonstrated strong cancer-fighting powers into cancer sufferers.

In 1999 Prof Cui and colleagues discovered a male mouse that appeared to be completely resistant to virulent cancer cells of several different types.

Since then more than 2000 mice in 15 generations have been bred from the original cancer-free mouse and 40 per cent of the offspring have inherited the immunity.

With the immune system, some types of cells which provide “innate immunity” are constantly on patrol for foreign invaders, while others have to firstly learn to identify a specific threat before going on the attack.

Scientists developing cancer vaccines have generally attempted to stimulate responses in the immune system cells that require prior exposure.

Last year Dr Cui caused shockwaves in the cancer research community when he identified granulocytes as the cells responsible for the mouse cancer immunity – because they are among those which act automatically.

Prof Gribben said: “This is surprising because it goes against how we thought immune system works against cancer. It makes us think again about our preconceived notions.”

Prof Cui injected granulocytes from immune mice into ordinary mice, and found it was possible to give them protection from cancer.

Even more excitingly he found the transfusions caused existing cancers to go into remission and to clear them completely within weeks.

A single dose of the cells appeared to give many of the mice resistance to cancer for the rest of their lives.

Granulocyte transfusion has previously been used to try to prevent infections in cancer patients whose immune systems have been weakened by chemotherapy.

However their effectiveness has been unclear because they have mainly been given to patients in an advanced stage of disease.

Prof Gribben warned the US researchers would have to be careful to avoid other immune system cells from the donor proliferating in the patient’s body.

He added: “If they’re using live cells there is a theoretical risk of graft-versus-host disease, which can prove fatal.”

But Dr Cui said he is working on ways to minimise this risk.

Blood test for cancer on way

Southampton: Scientists in the UK are working on ‘early warning’ blood test for cancer.

It looks for tell-tale signs in the blood long before symptoms appear and could save thousands of lives every year.

Doctors believe blood tests will revolutionise cancer prevention by offering cheaper and less invasive screening techniques.

The Southampton University research team is looking at blood samples collected by a GP from 11,000 Guernsey women over the last 30 years. Some of the women later developed-cancer, making their records especially valuable. The researchers looked for ‘ biomarkers’ – proteins produced by cancer cells.

Paul Townsend, who is leading the study, said: “Already we have seen significant bio-markers of breast cancer in the samples. The quality of the samples we have from Guernsey has been the key but it is early days.’

He adds: “of the ladies in the samples were healthy at the time but then went on to develop cancer. We are going back through these time capsules to look for things common in their blood that we can identify as a cancer fingerprint. We are trying to find out if we can take a sample from someone that is healthy and see if they could get cancer in the future.

‘We would like to establish a set of rules that we could look for.

‘It is early days in terms of our research but it’s looking very encouraging at the moment. ‘There’s a lot more work to be done but I’m hopeful we could have something in terms of a basic theory quite soon.’

Knee arthritis may be sign of lung cancer in smokers

Rome: Arthritis of the knee may be the first sign of a type of lung cancer that is hard to treat in heavy smokers, suggests research published ahead of print in the Annals of the Rheumatic Diseases.

The Italian researchers reviewed the case notes of all patients with rheumatic disorders, diagnosed at one tertiary referral centre over six years.

Between 2000 and 2005, more than 6500 new patients attended the clinic. Of these, 296 (4.4%) were cases of monoarthritis—inflammation in just one joint—of the knee.

Among this group of patients, the knee arthritis, which was very mild, was the first sign of as yet undiagnosed non-small cell lung cancer in just under 2%.

All the patients were middle aged men, who had been heavy smokers for most of their lives.

But in every case, the lung cancer was operable, and once the cancerous tissue had been removed, the knee symptoms subsided.

Non-small cell lung cancer is linked to other conditions, which feature abnormal growths, in up to 20 per cent of cases, say the authors. And spread to the bones occurs in around one in five cases.

But the authors note that it has not so far been linked to arthritis.

Non-small cell lung cancer is particularly difficult to treat unless caught early, and in over half the cases diagnosed, the disease is already advanced.

Features that could act as early warning signs are therefore especially important, say the authors.

More cervical cancer suffers are saved

Many cases of cervical cancer will soon be prevented because scientists now know what causes the disease.

In a report in The Lancet, a US specialist, Professor Mark Schiffman comments: “We hope to see a major decrease in the numbers of women affected with this cancer within our lifetimes.

“However, any large prevention effort should take into account further improvements such as inexpensive HPV testing, which will be available within a few years.”

Professor Schiffman, of the National Cancer Institute, National Institutes of Health, in Maryland, advises that women should be armed with the facts. He said almost all infections of the human papiloma virus, the trigger for cervical cancer, go away within a year or two; many within six months.

Cervical cancer is the second most common form of cancer in women worldwide with thousands dying from the disease. Smear tests, can pick up pre-cancerous cells so they can be treated before they become dangerous.

Grapefruit increases risk of breast cancer in older women

Los Angeles: Grapefruit raises levels of oestrogen and could increae the risk of breast cancer by nearly a third, says a joint study from the universities of Southern California and Hawaii.

Raised levels of the mainly female hormone oestrogen have been implicated in an increased cancer risk for women.

According to the researchers, eating as little as a quarter of a grapefruit a day raises the danger by 30 per cent among older post-menopausal women.

This is the first report of a commonly consumed food that may increase the risk of breast cancer among post-menopausal women.

The report published in the British Journal of Cancer says: “Whole grapefruit intake was significantly associated with breast cancer in the present study generally a 30 per cent increase among women who consume the equivalent of one quarter of a grapefruit or more per day. There is evidence that grapefruit increases plasma oestrogen concentrations.

“Since it is well established that oestrogen is associated with breast cancer risk, it is plausible that regular intake of grapefruit would increase a woman’s risk of breast cancer.’ The study, carried out by the universities of Southern California and Hawaii, was based on more than 50,000 postmenopausal women from five ethnic groups, including 1,657 with breast cancer.”

A number of lifestyle factors are also linked to breast cancer risk. For example, alcohol. fat and junk food consumption are said to increase the risks.
