Colon Cancer Stages
At its earliest stage (Stage 0), colon cancer is limited to the inner lining of your colon. As colon cancer progresses, it can grow through your colon and extend to nearby structures. The most advanced stage of colon cancer (Stage IV) indicates cancer has spread to other areas of the body, such as the liver or lungs.
