Test for breast cancer risk could reduce pre-emptive mastectomies

Researchers develop gene test that will give more detailed information on risk to women with BRCA1 and BRCA2 mutations

A genetic test that accurately predicts the risk of developing breast cancer could soon be used on high-risk groups.

Researchers behind the test say it could reduce the number of women choosing pre-emptive mastectomy surgery as they will be able to make more informed decisions about their care.
