Familial Adenomatous Polyposis
Medically reviewed by Drugs.com. Last updated on Jun 2, 2025.
Familial adenomatous polyposis (FAP) is a condition that causes multiple polyps to develop in your digestive system. Polyps are lumps of tissue that are usually benign (not cancer). Adenomatous polyps may turn into colorectal cancer if they are not treated. FAP greatly increases your risk for colon cancer. You also have an increased risk for other types of cancer.

Get screened as directed:
Screening means you are checked for polyps that may be cancer before you have signs or symptoms. Your provider will tell you when screening will start. You may be screened every 1 to 3 years. Timing depends on the number and location of the polyps.
Do not smoke:
Nicotine and other chemicals in cigarettes and cigars can damage blood vessels. This increases your risk for cancer and delays healing after surgery. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine. Ask your healthcare provider for information if you currently smoke and need help quitting.
