A diet low in animal fats and rich in fruits, vegetables, and whole grains may reduce the risk of colorectal cancer.

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.

Some studies suggest that people may reduce their risk of developing colorectal cancer by:

  • Increasing physical activity.
  • Keeping a healthy weight.
  • Eating a diet low in animal fats and high in fruits, vegetables, and whole grains.
  • Limiting alcohol consumption.
  • Avoiding tobacco.
