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.
This is why some treatment approaches are designed to attract the tumorâs blood supply so it will starve. Not all cancers spread, but any cancer can spread to any other part of the body. When it does take hold in an organ, it can grow in a disorderly fashion and interfere with the normal function of that organ. When cancer does spread, it more commonly metastasizes to vital organs such as the lungs, liver, bone, and brain. It may take months or even years for a microscopic metastasis to grow large enough to be seen on x-ray images or to cause symptoms.
