Video: Introduction to Genetics and Cancer

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.
