Even though we don't know the exact cause of most colorectal cancers, it is possible to prevent many of them. Screening is the main way to prevent colorectal cancer. Screening is the process of looking for cancer or pre-cancer in people who don't have any symptoms of the disease. Screening can prevent colorectal cancer by finding polyps. These can be removed before they have the chance to turn into cancer.
Other things that can help lower your risk are eating a healthy diet, getting exercise, and maintaining a healthy weight.
More information about preventing colorectal cancer can be found in Colorectal Cancer Prevention and Early Detection.
