what is the survival rate for colon cancer
Stage I cancers have a survival rate of 80-95 percent. Stage II tumors have survival rates ranging from 55 to 80 percent. A stage III colon cancer has about a 40 percent chance of cure and a patient with a stage IV tumor has only a 10 percent chance of a cure. Chemotherapy is used after surgery in many colon cancers which are stage II, III, and IV as it has been shown that it increases the survival rates.
