Colon Cancer Screening
You have a moderately increased risk of colon cancer. You should have your first colonoscopy no later than age 40. If your family member was diagnosed before age 50, you should have your first colonoscopy at an age ten years younger than the age of the family member when he or she was diagnosed. Colonoscopy should be repeated every five years.
