Other ways of screening

Colonoscopy and at-home tests are not the only options. Click on the links to learn more about each of the methods below.

Flexible sigmoidoscopy

This scope procedure looks inside the lower half of the colon but no further. It provides a visual exam, needs no sedation, and requires enemas for prep.

Guaiac fecal occult blood test (FOBT)

This is a non-invasive test that can detect small amounts of blood in stool. It requires abstaining from red meat and certain medications for a few days prior.

Double-contrast barium enema (DCBE)

Using X-rays to detect polyps or other abnormalities in the colon, a DCBE requires a laxative prep and clear diet the day before the sedation-free procedure.

Virtual colonoscopy

This test uses X-rays and computers to take 2- or 3-D images of your colon and rectum. It requires a clear liquid for a few days prior and uses no sedation.

Ask your doctor

Getting screened is important, but so is the method you choose. Talk to your doctor about your family history, personal health history, and your own preferences to find the best screening option for you.
