A wide range of colon conditions that cause symptoms can be diagnosed with colonoscopy.
A colonoscopy is also important for people without symptoms. Colorectal polyps are more common with age. These growths can sometimes become cancerous. You can’t feel polyps or early-stage colorectal cancer, which is why screening is so important. Removing polyps significantly lowers cancer risk.
During a colonoscopy, an endoscopist uses a colonoscope (a long, flexible tube with a camera attached) to examine the colon and rectum for polyps, cancer, and other conditions. Your doctor uses the colonoscope to biopsy tissue and remove polyps.
A colonoscopy is an outpatient procedure so you don’t need to stay overnight. You are sedated during the procedure, so you don’t experience discomfort or pain. Because of the sedation, someone needs to drive you home and be with you during recovery.
