Individuals at increased risk of developing colorectal cancer include those with a personal or family history of advanced adenomas or colorectal cancer, a personal history of inflammatory bowel disease, or genetic polyposis syndromes. In general, these persons should undergo more frequent or earlier testing than individuals at average risk. Individuals who have a first-degree relative with colorectal cancer or advanced adenoma diagnosed before 60 years of age or two first-degree relatives diagnosed at any age should be advised to start screening colonoscopy at 40 years of age or 10 years younger than the earliest diagnosis in their family, whichever comes first. In individuals with ulcerative colitis or Crohn disease with colonic involvement, colonoscopy should begin eight to 10 years after the onset of symptoms and be repeated every one to three years. Individuals who have a first-degree relative with hereditary nonpolyposis colorectal cancer should begin colonoscopy at 25 years of age and repeat colonoscopy every one to two years. In persons with a family history of adenomatous polyposis syndromes, screening should begin at 10 years of age or in a person's mid-20s, depending on the syndrome; repeat colonoscopy is typically required every one to two years. Screening colonoscopy should begin at eight years of age in individuals with Peutz-Jeghers syndrome. If results are normal, colonoscopy can be repeated at 18 years of age and then every three years. Persons with sessile serrated adenomatous polyposis should begin annual colonoscopy as soon as the diagnosis is established.
