Colon cancer is often subject to complications. The surgery does not guarantee that the cancer will not return. If the disease is untreated or if treatment does not work, the cancer can spread to the lymph nodes, then to the liver or lungs to form metastases. However, when chemotherapy and surgery are associated with a healthy lifestyle and anti cancer diet, your chance of survival is very high. If the cancer was detected at an early stage, you can be completely cured.
