Other factors that further the gamble of developing colon tumors are: mature down 40, the attendance of other diseases of the digestive tract, order history and ulcerative colitis.
Development of colon cancer at an at age, or at multiple sites, or recurrent colon cancer, suggests a genetically transmitted variety of the condition as opposed to the uneven form. There also is a slight increased hazard after colon carcinoma in the discrete who smokes.
The most run-of-the-mill colon cancer stall kidney is adenocarcinoma which accounts by reason of 95% of cases.
DIAGNOSIS
The development of polyps of the colon mostly precedes the development of colon cancer past five or more years. The American Gastroenterologial Confederation revised its screening guidelines in 2003 to recommend that people with two or more first-degree relatives with colorectal cancer or a first-degree reliant on with colon or rectal cancer previous ripen 60 should have a screening colonoscopy outset at seniority 40 or beginning 10 years last to the grow older of the earlier colon cancer diagnosis in their progeny (whichever is earliest). Those with a first-degree comparable diagnosed with colon cancer after time 60 or two second-degree affiliated with colon or rectal cancer should arise screening at time eon 40 with a given of the methods listed more than, such as annual sigmoidoscopy.

PREDICTION
Prognostication depends on the originate of the disease and the entire fettle of the patient. If diagnosed early, before the tumor has spread from the bowel, these treatments are acutely useful, with nearby 90% of patients among the living five years after diagnosis. If the colon cancer does not come underwrite (happen) within 5 years, it is considered cured. Projection is defective in patients with liver and lung metastases.
