To assess the condition of the colon and rectum, colonoscopy procedures are essential diagnostic instruments. The gastroenterologist can see the colon’s lining and identify anomalies like polyps, inflammation, or malignant growths by inserting a flexible tube to which a camera is attached during the surgery. Inflammatory bowel disease and colorectal cancer are two diseases that require colonoscopies to screen for and diagnose. The technique usually has little side effects and is very beneficial for early identification and prevention, even though it may cause some mild discomfort.
