In brief: Colonoscopy

If reason to suspect colon cancer colonoscopy is considered best.
Routine colonoscopy advocated by many M.D. Based upon age.

In brief: Colonoscopy.

While no test is 100% sure, colonoscopy is the most sensitive and specific, and it allows for biopsy and removal of polyps.
But it is also expensive. Other tests include fecal occult blood tests for screening in patients with no symptoms, flexible sigmoidoscopy, and air-contrast barium enema. These tests are not as complete.

In brief: By doing a scope.

Colonoscopy is the only sure way to know.
But unless you have symptoms like bleeding or pain, are over 50, or have a family history, there's probably no need to check. Ask your doctor if you should be checked.
