Is the cancer in your family inherited? Some families experience large amounts of cancer and whether it is environmental, every day living habits, or genetics are all factors that should be looked into. Genetic testing, usually performed with a blood sample, may provide information about you and an increased risk for cancer because of family genetics. For instance, nearly everyone born with familial adenomatous polyposis (the genetic predisposition to colon cancer) develops the disease by age 40 if preventive surgery isn't done. Knowing this early can aid in prevention and early detection. Talk with your doctor about genetic counseling. A Genetic Counselor provides individuals and families with information on the nature, inheritance, and implications of genetic disorders to help them make informed medical and personal decisions. Genetic counselors often work in clinics with oncologists or gastroenterologists and focus on cancer risk.
