colonoscopy

Colonoscopy is a medical procedure that is used to examine the colon (large intestine) and rectum for any abnormalities or signs of disease. The procedure involves inserting a long, flexible, and narrow tube called a colonoscope through the rectum into the colon and using a camera and light to view the inside of the colon. The colonoscope also allows the doctor to take tissue samples (biopsies) or remove polyps, which are small growths that can develop into cancer over time. Colonoscopy is an important screening tool for detecting colorectal cancer and is recommended for adults starting at age 50 or earlier if there are risk factors or symptoms. The procedure typically takes about 30-60 minutes and is done under sedation to minimize discomfort
