Familial Adenomatous Polyposis – FAP

Familial adenomatous polyposis (FAP) is a colon cancer predisposition syndrome characterized by the early onset of hundreds to thousands of adenomatous polyps throughout the colon. By age 35, 95% of individuals with FAP have polyps. If left untreated, patients with this syndrome develop colon cancer by age 35-40. APC-associated polyposis conditions are inherited in an autosomal dominant manner.
