Colorectal cancer is the third most common cancer and the second leading cause of cancer related deaths in the U.S. However, it is 90% preventable with early screening. Colon cancer screening should start at age 50 and occur every ten years or sooner, based on your risk for colon cancer, until age 75. Other screening options are available, such as annual fecal immunochemical testing. Talk to your doctor about which is best for you, especially if you have a family history of colon cancer as this puts you at higher risk.
