    What is (are) Colorectal Cancer ?
    ### Response:
    Several types of surgery are available for someone with colorectal cancer. If the cancer is found at a very early stage, the doctor may remove it without cutting through the abdominal wall. Instead, the doctor may put a tube up the rectum into the colon and cut the cancer out.
