Vicki Gilbert sits on stone steps in Wiltshire, England in this undated photo made available by the family on Tuesday, March 26, 2013. In 2010, Gilbert was diagnosed with breast cancer and then found she carries the mutated BRCA1 gene which may make her pre-disposed to ovarian cancer. Gilbert decided to have ovaries removed to prevent the potential onset of further cancer, and her breast cancer is in remission. A huge international effort involving more than 100 institutions and genetic tests on 200,000 people has uncovered dozens of signposts in DNA that can help reveal further a person’s risk for breast, ovarian or prostate cancer, scientists reported Wednesday, March 27, 2013. It’s the latest mega-collaboration to learn more about the intricate mechanisms that lead to cancer.
