Screening is important because many colorectal cancers can be prevented through regular screening. Additionally, if cancer is found early, colorectal cancer is highly treatable. Screening options for colon cancer include stool-based tests and an exam called a colonoscopy. It is generally recommended to start having colon cancer screening at age 45, regardless of gender. People at increased risk of colorectal cancer may start earlier, depending on your doctor’s instructions. It is important to talk to your doctor about your risk of colon cancer to determine the best screening plan for you.
