Can a preventative mastectomy prevent breast cancer?

ANSWER

A recent study suggests that prophylactic mastectomy may reduce the risk of breast cancer by up to 100% if there is a strong family history of breast cancer or a BRCA genetic mutation. However, risk reduction results vary widely for many reasons. In some studies, women had prophylactic mastectomies for non-high risk reasons, such as pain, fibrocystic breast disease, dense breast tissue, cancer phobia, or a family history of breast cancer.
