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.
Interaction between the tumor cell and potential host organ plays a key role; just as not all tumor cells are capable of metastasizing, not all organs can sustain one. A cancer that spreads to another part of the body is still considered the original type of cancerâcolon cancer that spreads to the liver is still colon cancer, for example, and is usually treated with drugs used for colon cancer. Many patients have evidence at initial diagnosis that tumor cells have spread beyond the primary site, Steeg says.
