He says that when you turn 50, you should begin having them. For people who are experiencing bleeding, have a family history of colon cancer or who have polyps, he says to see their doctor prior to the age of 50. 

Dr. Rosenfeld says during a colonoscopy he looks for growths in the colon. He explains the internal lining of colon sheds every 2 to 3 weeks, and if a cell does shed it will continue to replicate and can form a small bump, which can possibly lead to cancer.
