Study confirms HRT, cancer link

New evidence of a link between hormone replacement therapy and a raised risk of breast cancer has been put forward by U.S. researchers. The study in the New England Journal of Medicine found breast cancer risks fell sharply when women stopped taking HRT.

A UK expert says a 50 percent drop in HRT use in recent years had probably stopped up to 1,000 breast cancer cases a year.

The risks of HRT have been hotly debated since the Women's Health Initiative study linking combined estrogen and progestin with breast cancer.

Stanford researchers say their new findings should end the debate over the link.

However, some specialists insist that the fall in breast cancer rates may be due to other factors.
