Used to examine the colon and rectum for signs of disease such as polyps, bleeding, ulcers, inflammation, or tumors. It is often recommended for patients with unexplained gastrointestinal symptoms or a family history of colorectal cancer.

A non-invasive alternative that uses CT scans to produce images of the colon and rectum. While it does not require sedation, it cannot perform biopsies or remove polyps during the procedure.
Performed routinely to detect colorectal cancer early in asymptomatic individuals, usually starting at age 45–50. This preventive approach can help remove precancerous polyps before they develop into cancer.
Used for patients with a history of polyps, colon cancer, or inflammatory bowel disease. It is a follow-up procedure done at intervals to monitor for recurrence or progression.
