My doctor says I need to get a colonoscopy. What should I expect?

You should expect the procedure to last about 30 minutes and involve sedation. The doctor will insert a scope into your rectum and take biopsies of any abnormal tissue they find. They may also remove polyps, which are small growths in the colon that can become cancerous if left untreated. After the procedure is complete, you will be monitored for an hour or two before being released from the hospital.
