Reducing Risk of Death from Breast Cancer With Double Mastectomy

Women who have mutations in the Breast Cancer (BRCA) have an increased risk of developing breast cancer over their lifetime. The most common mutations that predispose one to breast cancer are observed in two genes called BRCA1 and BRCA2. Women who test positive for breast cancer-causing mutation in the BRCA1 gene can not only prevent the risk of developing the disease, but also reduce the risk of dying from it by choosing to undergo a double mastectomy, according to a new study.
