• Colorectal cancer typically develops from precancerous polyps or abnormal growths. Screening tests can find precancerous polyps, so that doctors can remove them before they become cancerous.
• The earlier the cancer is caught, the more effective treatment can be, resulting in much higher survival rates.  
• The U.S. Preventive Services Task Force notes that adults ages 45 to 75 need to be screened for colorectal cancer. Adults between the ages of 76 and 85 should talk to their doctor about screening options. 

People at an increased risk1 of getting colorectal cancer should talk to their doctor about when to begin screening, which test is right for them, and how often to get tested.
