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.
How cancer grows and spreads. Cancer is the growth of abnormal cells in the body. These extra cells grow together and form masses, called tumors. In colorectal cancer, these growths usually start as polyps in the large intestine (colon or rectum).If colon polyps aren't found and removed, they may turn into cancer.Cancers in the colon or rectum usually grow very slowly. It takes most of them years to become large enough to cause symptoms.If the cancer is allowed to grow, over time it will invade and destroy nearby tissues and then spread farther. Colorectal cancer spreads first to nearby lymph nodes.n colorectal cancer, these growths usually start as polyps in the large intestine (colon or rectum).
