The most run-of-the-mill colon cancer stall sort is adenocarcinoma which accounts for 95% of cases.
DIAGNOSIS
The evolution of polyps of the colon mostly precedes the maturing of colon cancer by five or more years. The American Gastroenterologial Confederation revised its screening guidelines in 2003 to underwrite that people with two or more first-degree relatives with colorectal cancer or a first-degree relative with colon or rectal cancer ahead age 60 should bear a screening colonoscopy outset at length of existence 40 or onset 10 years last to the age of the earlier colon cancer diagnosis in their kind (whichever is earliest). Those with a first-degree contingent on diagnosed with colon cancer after age 60 or two second-degree affiliated with colon or rectal cancer should upon screening at age 40 with a given of the methods listed first of all, such as annual sigmoidoscopy.

FORECAST
Projection depends on the originate of the infection and the inclusive health of the patient. If diagnosed untimely, first the tumor has spread from the bowel, these treatments are acutely able, with helter-skelter 90% of patients jumping five years after diagnosis. If the colon cancer does not come endorse (recur) within 5 years, it is considered cured. Projection is insufficient in patients with liver and lung metastases.
