Familial adenomatous polyposis (FAP) is a rare inherited condition.Less than 1 - 2% of all bowel cancers in the general population are due to FAP. The most common indication of FAP is the development of 100s to 1000s of polyps in the large bowel (intestine).
Polyps are small mushroom-like growths with stalks that vary in size from a tiny pinhead to 2 cm or more. A colectomy is recommended in most cases by the age of 20. Research shows about 90% of bowel cancer can be cured if picked up at the earliest stage.
