Can bowel polyps cause bowel cancer?

Removing a polyp interrupts that possible pathway and lets a laboratory examine the tissue for cell changes.

A bowel polyp is a growth on the inner lining of the colon or rectum. Different types behave differently: some have no meaningful potential to become cancer, while adenomatous and certain serrated polyps can acquire further abnormal changes over time.

The pathology report identifies the polyp type and whether dysplasia, meaning abnormal cell development, is present. Its size, number, location, removal completeness and microscopic features help the clinical team plan follow-up. A polyp containing cancer cells may require additional assessment to determine whether removal was complete and whether any further treatment is appropriate.

Have the polyp removed if your endoscopy team recommends it; many can be removed during colonoscopy. Wait for the pathology result rather than judging risk from symptoms, because polyps often cause no noticeable change.

Follow the surveillance plan recorded by your specialist. The timing of another bowel examination depends on the findings from this procedure and your personal and family history. Keep a copy of the colonoscopy and pathology reports, and tell close relatives if your clinician identifies an inherited polyp syndrome or recommends family assessment.

Arrange a medical assessment for blood in the stool, bleeding from the rectum, a persistent change in bowel habit, unexplained weight loss or recurring abdominal discomfort. These symptoms have several possible causes, and an examination can identify what is responsible.

Seek urgent care for heavy or continuing rectal bleeding, black or dark-red stool, severe abdominal pain, fainting, marked dizziness or weakness. After polyp removal, follow the discharge instructions and urgently report worsening pain, fever or substantial bleeding.

Ask what type of polyp was removed, whether it showed dysplasia or cancer, whether the edges were clear, and when your next bowel check should be. Also ask whether the number or pattern of polyps suggests that relatives need advice or testing.
