What is colorectal cancer?

Most colorectal cancers start in the cells that line the inside of the colon or the rectum. The colon and rectum make up the large intestine (large bowel). The large intestine is the last part of the digestive system. Organs of the digestive system change food into energy and help pass waste out of the body.

Food is digested in the stomach and the small intestine. As nutrients are removed from food, it changes into a watery mass. The watery mass passes through the small intestine into the colon. The colon absorbs the water and the semi-solid waste continues to travel to the rectum. This waste material is known as feces or stool. The stool is stored in the rectum. When you have a bowel movement, the stool leaves the body through the anus.

Colorectal cancer usually grows slowly and in a predictable way. It is curable when diagnosed at an early stage.
