Colorectal cancer risk and prevention

Cancers in the colon or rectum usually grow very slowly. In most cases, it takes years for them to grow large enough to cause symptoms. While you may not be able to control all risk factors, you may be able to lower your risk by taking steps to improve your overall health. Talk with your doctor to understand your level of risk and discuss whether you need a screening.

What puts you at risk for colorectal cancer?

A risk factor for colorectal cancer is something that increases your chance of getting this cancer. Having one or more of these risk factors can make it more likely that you will get colorectal cancer. But it doesn't mean that you will definitely get it. And many people who get colorectal cancer don't have any of these risk factors. Risk factors include age, race, lifestyle, your family's medical history and your personal medical history.

Who is at increased risk for colorectal cancer?  

Some people are more likely to get colorectal cancer than others. This includes people who:

  • Already have been diagnosed with colorectal cancer.
  • Have a first-degree relative with a certain type of polyp or colorectal cancer. A first-degree relative is a parent, brother, sister, or child.
  • Have had one or more polyps removed from your colon.
  • Are African American.
  • Have inflammatory bowel disease. This includes ulcerative colitis or Crohn's disease.
  • Have a rare inherited polyp syndrome, such as FAP or Lynch syndrome.

Experts agree that people who have a higher risk for colorectal cancer may need to be tested sooner. Talk to your doctor about when you should be tested. Your doctor may recommend testing earlier or more often.
