    Colon cancer or colorectal cancer is the second most deadly form of cancer in the United States and Colorado, in part because people are often embarrassed to be screened for the disease. Colon cancer rates increase sharply in both men and women after age 50.

    The most common symptom of colon cancer is no symptoms at all, making colonoscopy screenings extremely important in detecting the cancer early when it is most treatable. A colonoscopy is recommended for all people at age 50, or earlier if you have been identified as having an increased risk of colon cancer.
