What can you do to reduce your risk of colorectal cancer?
Overall, the most effective way to reduce your risk of colorectal cancer is to get screened for colorectal cancer routinely, beginning at age 45.
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.
Researchers are looking at the role of some medicines and supplements in preventing colorectal cancer.
