|Title||Increased breast cancer risk - Million women study.|
|Full Story||Further information published in The Lancet, from the Million women study, has shown a greater increase in the risk of breast cancer in women taking combined HRT than previously believed. The million women study, analysing information from women attending for breast cancer screening between 1996 and 2001, has reported that about 20 women per 1,000 usually develop breast cancer. For every 1,000 women aged over 50 taking oestrogen combined with progestogen for 10 years, there were 19 extra cases of breast cancer, and an extra 5 cases in women taking oestrogen only (the type of HRT usually used by women who have had a hysterectomy). The increased risk was previously quoted as an extra 6 cases per 1,000 women aged 50-70 taking HRT for 10 years, with a baseline risk of 45 per 1,000.
