Familial Adenomatous Polyposis

Familial adenomatous polyposis (FAP) is an inherited condition that will lead to colon cancer if untreated. It is marked by abnormal benign growths, or polyps, in the colon (the large intestine) or rectum.

FAP: what you should know

  • One percent or less of colon cancers result from FAP, a genetic condition. If you have a parent, child or sibling with FAP or FAP-related colon cancer, you may be at risk.
  • If you have FAP, you can develop polyps as early as age 13. As you age, you will develop more polyps, ranging from a hundred to possibly thousands.
  • Colon polyps rarely have symptoms until they are advanced, which may be too late. Rectal bleeding, or a change in your bowel habits lasting a week or longer, may be signs of an advanced polyp or colon cancer.
  • Polyps are best detected and sampled or removed  by a test called a colonoscopy, in which doctors insert a long tube to view the colon. If the colonoscopy findings are suspicious for FAP, doctors can confirm the diagnosis of familial adenomatous polyposis through genetic testing.
  • Colon cancer arising from FAP can be prevented by removing the colon before cancer develops.
