stage IV colorectal cancer


(...KOH-loh-REK-tul KAN-ser)
Stage IV colorectal cancer is divided into stage IVA and stage IVB. In stage IVA, cancer may have spread through the colon and/or rectal wall and may have spread to nearby organs or lymph nodes. Cancer has spread to one organ that is not near the colon and/or rectum, such as the liver, lung, or ovary, or to a distant lymph node. In stage IVB, cancer may have spread through the colon and/or rectal wall and may have spread to nearby organs or lymph nodes. Cancer has spread to more than one organ that is not near the colon and/or rectum or into the lining of the abdominal wall.
