What Can I Do to Reduce My Risk of Colorectal Cancer?
“I’ve been screened twice. I made everybody I love get screened,” says actress Meryl Streep in this video. “People that are screened early and find cancer and are treated early—they’re alive because of that early detection.”
Overall, the most effective way to reduce your risk of colorectal cancer is to get screened for colorectal cancer routinely, beginning at age 45.
Almost all colorectal cancers begin as precancerous polyps (abnormal growths) in the colon or rectum. Such polyps can be present in the colon for years before invasive cancer develops. They may not cause any symptoms, especially early on. Colorectal cancer screening can find precancerous polyps so they can be removed before they turn into cancer. In this way, colorectal cancer is prevented. Screening can also find colorectal cancer early, when treatment works best.
Research is underway to find out if changes to your diet can reduce your colorectal cancer risk. Medical experts often recommend a diet low in animal fats and high in fruits, vegetables, and whole grains to reduce the risk of other chronic diseases, such as coronary artery disease and diabetes. This diet also may reduce the risk of colorectal cancer.
