A colonoscopy can be a dreaded procedure, but it can save your life. During a colonoscopy, the patient is sedated, and a camera is used to search the colon for abnormalities.
Even if you have misgivings, doctors recommend most people get a colonoscopy by the time they're 50. Those with a family history of colon cancer should start screening even earlier.
Sara Ballard is 61. She's getting a colonoscopy, just to be safe.
"My family has a history of cancer, so I just want to be aware. My sister had polyps. I went with her and knew it was time for me to get one too," explains Ballard.
