Colonoscopy

Colonoscopy

Overview

There are 4 basic tests for colon cancer: a stool test (to check for blood), sigmoidoscopy (inspection of the lower colon), colonoscopy (inspection of the entire colon), and double contrast barium enema. All 4 are effective in catching cancers in the early stages, when treatment is most beneficial.
