For people with colon cancer, treatment by stage refers to treating the disease based on how far it has progressed. For instance, in the early stages of colon cancer, surgery may be the only treatment required. In later stages of the disease, surgery may be combined with chemotherapy and/or radiation therapy. The following article breaks down colon cancer treatment by stage, from stage 0 through stage IV and recurrent cancer.

• Surgery (see Colon Cancer Surgery)
• Chemotherapy (see Colon Cancer Chemotherapy)
• Radiation therapy (see Radiation Treatment for Colon Cancer).
   

• The stage of the cancer (see Colon Cancer Stages)
• Whether the cancer has recurred (come back)
• The patient's age and general health.
   

• Local excision or simple polypectomy
• Resection/anastomosis (this is done when the cancerous tissue is too large to remove by local excision).
