Drug that prevents half of breast cancers carries on working

Drug that prevents half of breast cancers carries on working A drug that halves a woman's risk of breast cancer continues to work long after they stop taking it, say researchers.

Anastrozole blocks the production of the hormone oestrogen, which fuels the growth of many breast cancers.

It is already available on the NHS, but researchers at Queen Mary University of London said only a tenth of eligible women were receiving it. BBC News
