FAP stands for Familial Adenomatous Polyposis. Individuals with FAP have an increased chance of developing cancer. People with FAP develop multiple polyps (small growths) in their bowel. The polyps usually begin to appear in adolescence, but the age at which they develop can be variable. The polyps themselves are not dangerous, but if they are left untreated one or more will turn into cancer. The condition affects both men and women.
