10 Signs of Colon Cancer

10. Urge to Defecate

An urge to have a bowel movement that isn't relieved by using the bathroom could be a sign of colon cancer. This is different from constipation, in which bowel movements are infrequent or difficult to pass. With an increased urge to defecate, there may be a bowel movement, but the urge to go remains. This symptom is more commonly seen in patients who have cancer in the distant colon or the rectum. It is caused by increased pressure exerted on the bowel by cancer. If you are feeling an urge to empty your bowels, but this sensation does not go away after using the bathroom, it could be a sign of colon cancer.
