Colon Cancer is a disease afflicting humans and is a malignant tumor, which arises from the inner wall of the large intestine (colon), or the rectum (which is the end of the colon). It is also referred to as colorectal cancer. In the United States, it is the third leading cause of cancer in males, and fourth in females.
The human colon is a tube shaped muscular organ which is about four feet in length, extending from the small bowel to the anus. It has three main functions, which are digest and absorb nutrients from the food, to concentrate fecal material by absorbing fluids, and store fecal material and control its evacuation.
