Colonoscopy

There are four basic tests for colon cancer: a stool test (to check for blood); a barium enema (x-ray) test; sigmoidoscopy (inspection of the lower colon); and colonoscopy (inspection of the entire colon). All four can detect cancers in the early stages, when treatment is most beneficial, but colonoscopy is the most accurate.
