Description:
Stage IV colorectal cancer is divided into stages IVA, IVB, and IVC. In stage IVA, cancer has spread to one area or organ that is not near the colon and/or rectum, such as the liver, lung, ovary, or a distant lymph node. In stage IVB, cancer has spread to more than one area or organ that is not near the colon and/or rectum, such as the liver, lung, ovary, or a distant lymph node. In stage IVC, cancer has spread to the tissue that lines the wall of the abdomen and may have spread to other areas or organs.
