Familial Adenomatous Polyposis (called “FAP”) is a disease that causes abnormal growths in the large intestine (also called the colon), rectum and other areas. Doctors call these growths “polyps.” They are not cancer, but can turn into cancer.
Most people with FAP have hundreds or thousands of polyps. This means they have a much higher risk of colon cancer than other people. Without treatment, almost all people who have FAP will develop colon cancer. Some people have a milder form of FAP that causes fewer polyps.
