Anastrozole is the name of a drug previously used to treat breast cancer in post-menopausal women. It is now being offered to some women after menopause as a preventative measure, with protective effects proven to last years post-treatment.
It's thought that an estimated 289,000 women in the UK could benefit from taking anastrozole, with recent trials showing it has the potential to reduce the risk of breast cancer in postmenopausal women with a moderate to high risk of developing the disease by almost 50%.
