Types of Cancer :: What is Colon Cancer?

Colon cancer is a disease in which malignant (cancer) cells form in the tissues of the colon.

The colon is part of the body's digestive system . The digestive system removes and processes nutrients (vitamins , minerals , carbohydrates , fats, proteins , and water) from foods and helps pass waste material out of the body. The digestive system is made up of the esophagus , stomach , and the small and large intestines . The first 6 feet of the large intestine are called the large bowel or colon. The last 6 inches are the rectum and the anal canal. The anal canal ends at the anus (the opening of the large intestine to the outside of the body).
