Does colonoscopy treat familial adenomatous polyposis?

FAP causes numerous polyps to develop in the large bowel and can also affect other parts of the digestive tract. Colonoscopy lets a specialist examine the colon, remove some accessible polyps, and collect tissue for laboratory assessment. When polyps are numerous, large, or difficult to remove safely, repeated polyp removal may not control the bowel burden. In that situation, a colorectal team may discuss an operation that removes affected bowel. Even after surgery, the inherited tendency remains and the rectum or upper digestive tract may need surveillance.

Follow the schedule set by your specialist rather than waiting for symptoms, because polyps may be present without causing discomfort. Ask how the team will track polyp size and number, whether a site needs advanced removal, and what findings would make surgery worth discussing. Genetic counselling can help relatives understand their own assessment options. Read more about [Colonoscopy](/treatments/cancer-screening/colonoscopy/).

Arrange prompt medical review for rectal bleeding, persistent change in bowel habit, new or worsening abdominal pain, unexplained weight loss, or unusual tiredness. Seek urgent help for heavy bleeding, severe pain with vomiting, a swollen abdomen, inability to pass stool or gas, fainting, or sudden weakness. These symptoms can indicate bleeding or bowel obstruction and should not wait for a routine surveillance appointment.

How many polyps were found and removed? Is colonoscopy still controlling the bowel findings? When should surgery be considered? Which stomach, small-bowel, or rectal checks are part of my plan?
