Colon cancer is one of the few cancers that can be prevented and detected through early diagnostic screenings. Colorectal cancer often begins with the formation of polyps in the colon – these polyps are small, rounded growths that extend from the colon wall and are attached by a narrower “stalk” of tissue. Polyps themselves are harmless, but some may develop into cancer if not removed. Since polyps and early-stage colon cancer are “silent” (producing no symptoms), screening procedures are the only means of detecting and treating them. Colon cancer screening should begin at 50 for most people; however, if you have a family history of colorectal cancer, screenings could start as early as 40. Most screenings involve a colonoscopy, fecal occult blood test (FOBT), flexible sigmoidoscopy or a stool DNA test. Your doctor will discuss what screening is best for you.
