genetic testing

Sometimes all it takes is one celebrity's simple, powerful story to help women realize the health options they have.

Movie star Angelina Jolie, told she was at high risk for breast cancer, underwent a preventive double mastectomy, but a prominent cancer geneticist tells AARP the actress should also consider removing her ovaries to reduce her risk of deadly ovarian cancer.
