Scientists have found a strong link between specific genes and certain cancers such as breast, ovarian, and colorectal cancer. Kenneth Offit, Chief of the Clinical Genetics Service at Memorial Sloan Kettering Cancer Center, talks about the complex interplay between genetics and cancer, who should be tested, and what people can do if they discover they have a higher risk for cancer. Dr. Offit also explains how information about the genetic makeup of a tumor may lead to the development of more-targeted therapies for cancer, and can help doctors select the most-effective treatments available.
