DIAGNOSIS
The evolution of polyps of the colon large precedes the maturing of colon cancer past five or more years.

Those with a first-degree subordinate to diagnosed with colon cancer after stage 60 or two second-degree correspondent with colon or rectal cancer should enter on screening at time eon 40 with identical of the methods listed above, such as annual sigmoidoscopy.
