Abstract:
There is good evidence from faecal occult blood testing trials that detection and removal of non-advanced colorectal neoplasms can achieve a reduction in colorectal cancer mortality. Both colonoscopy and barium enema have potential advantages and disadvantages if implemented for population screening. The relative merits of each are discussed.
