Study finds risk of breast, ovarian cancer dependent on type of BRCA1 or BRCA2 mutation

In a study of more than 31,000 women who have inherited mutations in BRCA1 or BRCA2 genes, researchers determined that the level of risk for breast and ovarian cancer is dependent on the type of mutation, a finding they believe may lead to better prevention strategies. According to the National Cancer Institute, breast cancer is the most commonly diagnosed cancer after nonmelanoma skin cancer among women in the United States, and it is the second leading cause of cancer deaths after lung cancer.

The study, published in the April 7 issue of the Journal of the American Medical Association (JAMA), was conducted by researchers at the Basser Center for BRCA, the Abramson Cancer Center and the Perelman School of Medicine at the University of Pennsylvania.
