Colonoscopy
A colonoscopy is a routine procedure and screening where a doctor examines the inside of the colon and rectum for signs of colon cancer, polyps and more.

A colonoscopy is a safe, routine procedure that can reduce your risk of colon cancer by 60-90%. It also lets your doctor evaluate conditions like bleeding, chronic diarrhea and anemia. At Sutter, our providers work together to prioritize your needs for the most thorough, comfortable screening possible. During the procedure, your doctor will use an endoscope, a flexible tube with a video camera, to examine the inside of your large intestine and rectum. This allows your doctor to detect and remove precancerous and cancerous polyps, close wounds, inject medications and place stents.
