A small percentage of women, less than 4%, would benefit from this treatment whilst hundreds of others are exposed to the risk of side effects. In addition, there will be a significant cost to the NHS for providing this medication to all of those women.
It is a very difficult job to balance the risks, costs and benefits of treatments such as these and undoubtedly there will be people who feel strongly on both sides of the debate.
Hundreds of thousands of healthy women should take pills to cut their risk of breast cancer, says NHS watchdog NICE. The draft guidelines for England say women predisposed to breast cancer because of a strong family history of the disease need this protection. There are now three drugs to choose from - tamoxifen, raloxifene and, for the first time, anastrozole. Anastrozole is cheaper than the other two and, for some women, has fewer side-effects and is more effective. Trials show that per 1,000 patients taking anastrozole for five years, 35 cancer cases would be prevented compared with 21 for tamoxifen.
