Perfecting and Personalizing Risk Assessment with Dr. Katherine Nathanson

While breast cancer is not typically caused by inherited factors, as many as 10-15 percent of people diagnosed with breast cancer carry a known genetic mutation. The most well-known mutations are in the BRCA1 and BRCA2 genes. But these only account for 5-10 percent of inherited breast cancers, so what about the many other gene mutations that increase a person’s risk of breast cancer? Also, what does this mean not only for genetic testing—but also how we should consider results? More significantly, what effect might this have on the personalization of risk? We talk with BCRF investigator and cancer geneticist Dr. Katherine Nathanson to answer these questions.
