Question: What is the difference in the stages of colon cancer? my boyfriend has 4th stage colon cancer. They removed some of the colon. they now say both lobes of his liver have cancer spots and they are concerned about a spot on his lung.

Answer: As colon cancer progresses from Stage 0 to Stage IV, the cancer cells grow through the layers of the colon wall and spread to lymph nodes and other organs. Stage 0 (Carcinoma in Situ) In stage 0, abnormal cells are found in the innermost lining of the colon. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. Stage I In stage I, cancer has formed and spread beyond the innermost tissue layer of the colon wall to the middle layers. Stage I colon cancer is sometimes called Dukes A colon cancer. Stage II Stage II colon cancer is divided into stage IIA and stage IIB. Stage IIA: Cancer has spread beyond the middle tissue layers of the colon wall or has spread to nearby tissues around the colon or rectum. Stage IIB: Cancer has spread beyond the colon wall into nearby organs and/or through the peritoneum. Stage II colon cancer is sometimes called Dukes B colon cancer. Stage III Stage III colon cancer is divided into stage IIIA, stage IIIB, and stage IIIC. Stage IIIA: Cancer has spread from the innermost tissue layer of the colon wall to the middle layers and has spread to as many as 3 lymph nodes. Stage IIIB: Cancer has spread to as many as 3 nearby lymph nodes and has spread: beyond the middle tissue layers of the colon wall; or to nearby tissues around the colon or rectum; or beyond the colon wall into nearby organs and/or through the peritoneum. Stage IIIC: Cancer has spread to 4 or more nearby lymph nodes and has spread: to or beyond the middle tissue layers of the colon wall; or to nearby tissues around the colon or rectum; or to nearby organs and/or through the peritoneum. Stage III colon cancer is sometimes called Dukes C colon cancer. Stage IV In stage IV, cancer may have spread to nearby lymph nodes and has spread to other parts of the body, such as the liver or lungs. Stage IV colon cancer is sometimes called Dukes D colon cancer.
