Conditions InDepth: Colorectal Cancer
Colorectal cancer is a disease in which cancer cells grow in either the colon or the rectum. The colon and rectum are parts of the body’s digestive system. They remove nutrients from food and store waste until it passes out of the body. The colon and the rectum also absorb water from ingested materials. Normally, the cells in the colon and rectum divide in a regulated manner. If cells keep dividing when new cells are not needed, a mass of tissue called a tumor forms. A tumor can be benign or malignant.
