There are 3 parts to stage III 3A 3B and 3C. Stage IIIB has a 5-year survival rate of about 56-60%. As the stage gets higher the survival rate gets lower. Which stage 3 a colon cancer falls is determined by a combination of the depth of invasion and the number of lymph nodes involved. This tells us statically how likely the disease will progress. Colon cancer is a stage IV when cancer has spread to a distant site. It is most often the liver, but it does not have to be. The survival rate is so much lower because once cancer has spread to a distant site we know cancer cells are circulating in the body and it is nearly impossible to stop them.
