Hello thank you for trusting HCM Dear Colorectal cancer treatment depends on the size, location and how far the cancer has spread. Common treatments include surgery to remove the cancer, chemotherapy and radiation therapy. stage 1: surgery stage 2:Many stage II rectal cancers have grown through the wall of the rectum and might extend into nearby tissues. They have not yet spread to the lymph nodes. chemo+radio+surgery stage 3 :Stage III rectal cancers have spread to nearby lymph nodes but not to other parts of the body. surgery+chemo+radiation Stage 4:rectal cancers have spread to distant organs and tissues such as the liver or lungs. Treatment options for stage IV disease depend to some extent on how widespread the cancer is. dear please consult your surgeon he will investigate depending on stage of disease he will treat you. take care
