Of cancers affecting both men and women, colorectal cancer (cancer of the colon and rectum) is the second leading cancer killer in the United States, but it doesn’t have to be. Screening can find precancerous polyps—abnormal growths in the colon or rectum—so they can be removed before turning into cancer. Screening also helps find colorectal cancer at an early stage, when treatment often leads to a cure. If you are 50 years old or older, get screened now.

  • Learn your family history of cancer and tell your doctor if you think you may have a higher risk.
  • Don’t smoke.
  • Get enough physical activity and limit your alcohol consumption.
  • Talk to your doctor if you have blood in or on your stool (bowel movement); stomach pain, aches, or cramps that don’t go away; or are losing weight and you don’t know why.
