HRT blamed for 1,000 ovarian cancer deaths

London: Women taking hormone replacement therapy are 20% more likely to suffer from ovarian cancer, claims a new report. More more than 1,000 women died in the last 15 years after contracting ovarian cancer following hormone replacement therapy it says.

The study published in the latest issue of The Lancet medical journal etimates that 70 deaths a yar are connected to taking the therapy which is dogged with controversy and confusion.

US researchers recently produced evidence to suggest that women int heir 50s on HRT are protected from heart attachs and premature death. This contradicted earlier claims that it put women at risk of heart disease.

This latest study, sponsored by Million Women Study, was started in 1996 suggests that more than 1,300 extra cases of ovarian cancer occured between 1991 and 2005. Of these women, 1,000 died of the disease. It reveals a 20 per cent increase in risk of the disease in women who have taken HRT for at least five years, but says it does not persist if women give up. The study, largely funded by Cancer Research UK, looked at responses from 948,576 postmenopausal women over seven years. It has previously linked HRT with breast cancer.

Overall the statistics mean that over a five-year period there is likely to be one extra case of ovarian cancer among every 2,500 women receiving hormone replacement therapy. For every 3,300 women on HRT, there is estimated to be one additional death from ovarian cancer.

HRT prescribed by the UK’s National Health Service is artificially made hormone replacement usually made from mare’s urine. It is used to combat symptoms of the menopause, including hot flushes, vaginal dryness and night sweats, with a range of drugs including tablets, implants and patches.

Safety concerns led to drug regulatory authorities in the UK and other countries issuing restrictions, including the advice to use it for the shortest time possible, which have continued to deter women from getting treatment. It has been blamed for both womb and breast cancer.GP data shows the number of British women on HRT halved from two to one million between 2002 and 2005.
