Survival rates for any cancer are often reported by stage, the extent of spread when the cancer is identified. For colon and rectum cancer, around 39% are diagnosed at the local stage, before the cancer has spread outside the local area. The five-year survival for these patients with localized colon and rectum cancer is around 90%.
When the cancer has spread to the regional lymph nodes near the site of origin, the five-year survival rate is about 71%. When the cancer has metastasized to distant sites in the body (stage IV cancer), the five-year survival rate lowers to about 14%.
