Colon cancer is, as its name suggests, a disease that affects the colon. The colon is a tube shaped organ, located in the abdomen, that starts at the end of the bowel and ends with the anus. It twists and turns a lot, so its length is over 4 feet. The functions of the colon are to digest the food, absorb the nutrient substances from it (proteins and aminoacids), and to create the concentrated fecal material, which is then stored and eliminated from the colon when the time comes. The end of the colon is called rectum. The rectum and the colon together form the large intestine.
