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.
Cancer begins when a cell begins dividing uncontrollably. Eventually these cells form a visible mass or tumor. This initial tumor is called the primary tumor. Cells from the primary tumor can break off and lodge elsewhere in the body where they then grow into secondary tumors. This process is called metastasis and a cancer which has spread to other organs is called metastatic.. When cancer spreads to another organ, the type of cancer remains the type of the primary tumor. Thus cancer that started in the colon and spread to the liver is still colon cancer. It is not liver cancer.
