The cause of colorectal cancer is not understood and appears to involve interactions between inherited susceptibility and environmental factors. Environmental factors play an important role and can increase the risk of colon cancer. The symptoms of colorectal cancer are similar to that of many other bowel disorders, but early colon cancer is asymptomatic. The risk of developing colorectal cancer rises sharply after the age of 40 years. A person under 40 years with positive family history should be investigated. It is appropriate to perform one or all the following in the order to make a firm diagnosis.
