A colonoscopy is a procedure where a doctor inserts a flexible tube with a camera into your rectum to examine your colon. The colon is inflated with air or CO₂ to get a clear view of the lining. This helps detect polyps, bleeding, inflammation, or early signs of cancer. If anything unusual is found, the doctor can remove tissue for biopsy during the procedure. It’s an important screening tool for colorectal health.Video Credits: Medical Animation Media, Medical Arts, Specialty Surgical Oncology
