Your Guide to Colorectal Cancer Screening

Colorectal cancer is one of the most preventable cancers and screening is the most powerful tool we have to detect problems early, when treatment is most effective. Screening has the strongest evidence for reducing deaths from colorectal cancer. With updated national recommendations, now is a perfect time to make sure you’re up to date on your screening plan. 

Why Screening Matters 

Most colorectal cancers begin as small growths called polyps. Screening can detect these polyps before they turn into cancer — or find cancer early, when outcomes are best. Screening tests are now easier and more flexible than ever. 

When Should You Get Screened? 

Adults at average risk should begin screening at age 45. Some people may need to begin earlier, this includes people with a family history of colorectal cancer or certain types of colon polyps, people with hereditary cancer syndromes, and people with Inflammatory Bowel Disease. Talk with your primary care provider to figure out when you should start regular screening based on your personal risk factors. 

Depending on your health, family history, screening method preferences, and the outcome of your initial screening, you will get a recommendation to get screened regularly every 1 to 10 years until age 75. After age 75, screening becomes optional and dependent on your overall health, prior screening history, and personal preferences. 

Screening Options 

You and your provider can choose from several safe and effective tests: 

Colonoscopy 

  • Performed in-clinic at a procedure center or hospital 
  • Recommended every 10 years if normal 
  • Bowel prep required: Yes 
  • Sedation recommended: Yes 
  • Recovery time: 1 day 

Colonoscopy is the gold standard for colorectal cancer screening because it allows for direct, full visualization of the colon and the ability to detect and remove precancerous polyps during a single procedure. The procedure uses a long, flexible tube, about the diameter of a thumb, with a tiny camera to look inside your colon and rectum. 

CT Colonography (a.k.a. Virtual Colonoscopy) 

  • Performed in-clinic at an imaging center or hospital 
  • Recommended every 5 years if normal 
  • Bowel prep required: Yes 
  • Sedation recommended: No 
  • Recovery time: None 
  • A noninvasive test that uses a CT scan to create detailed 3D images of the colon and rectum to look for polyps or signs of cancer. If this test is abnormal, a follow-up colonoscopy will be needed to find and remove the polyps. 

Stool DNA test (e.g. Cologuard) 

  • Performed at home 
  • Recommended every 3 years if normal 
  • Bowel prep required: No 
  • Sedation recommended: No 
  • Recovery time: None 

A non-invasive stool test you can perform by yourself at home. The test checks for hidden blood and DNA changes linked to cancer or polyps. If this test is abnormal, a follow-up colonoscopy will be needed to find and remove the polyps. This test is not recommended for patients who are considered high-risk.
