What does colonoscopy treat?

Short answer
Colonoscopy mainly examines the bowel; it can remove some polyps and take biopsies, but it does not treat every bowel cancer.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.
At a glance
- Main role
- Examine the lining of the large bowel
- May happen during the test
- Biopsy, polyp removal, or local bleeding control
What happens during colonoscopy
A flexible camera passes through the back passage to inspect the lining of the rectum and colon. The clinician may remove a small polyp, stop a local source of bleeding, or take a biopsy for laboratory examination. Colonoscopy can identify changes linked with Bowel Cancer, Bowel Polyps, Familial Adenomatous Polyposis, or Lynch Syndrome, but a finding may need other treatment or surgery.
Preparing for the test
Follow the bowel-preparation instructions so the lining can be seen clearly, including advice about food, fluids, and regular medicines. Arrange transport and support if sedation is planned. Tell the endoscopy team about blood-thinning medicines, allergies, pregnancy possibility, and previous reactions to sedation.
When to seek care
After colonoscopy, seek urgent advice for severe or worsening abdominal pain, persistent vomiting, fever, fainting, heavy rectal bleeding, or a swollen abdomen. Small amounts of bleeding can occur after a polyp is removed, but follow the specific instructions from your endoscopy team.
Questions for your doctor
Ask why colonoscopy is recommended, whether a biopsy or polyp removal may happen, how to manage medicines before the test, and when results will be discussed. Ask what other treatment would be considered if a suspicious area is found.
Questions people ask
Does colonoscopy remove bowel cancer?
It may sample a suspicious area, but many bowel cancers require treatment beyond the procedure, such as surgery or other oncology care.
Can polyps be removed during colonoscopy?
Often, suitable polyps can be removed during the procedure and sent for examination.
