A UCLA Health answered. Colon cancer can cause a person to feel tired or weak, lose weight, and have general discomfort in their digestive system and bowel movements. In the later stages of colon cancer, the cancer can spread beyond the rectum into other parts of the body. In stage III colon cancer, the lymph nodes that reside nearby are infected. In the final stage of colon cancer, stage IV, the cancer has spread to other organs, such as the liver or lungs.
Stage IV colon cancer commonly spreads to the liver or the lungs. Some patients who have cancer that has spread to a single area are candidates for surgery to remove the metastases. Treatment of the liver: When itâs possible to completely surgically remove all liver metastases, surgery is the preferred treatment.hen the site of metastasis is a single organ (such as the liver), and the cancer is confined to a single defined area within the organ, patients may benefit from local treatment directed at that single metastasis. The majority of patients diagnosed with Stage IV colon cancer have unresectable or widespread disease.
