Familial adenomatous polyposis (FAP) is an inherited genetic condition that causes the growth of hundreds to thousands of polyps (abnormal mushroom-shaped growths of tissue) in a patient’s lower intestine (including the colon and rectum). Polyps may be seen in a patient’s upper intestine as well. About one in 30,000 people is affected with FAP. Polyps usually begin to grow in patients at about age 10 to 12. Initially, these polyps do not cause symptoms in most patients. However, they greatly increase the risk of colon cancer, in which cells in the colon divide uncontrollably and develop into tumors. Almost all patients with FAP develop colon cancer by age 40.
