Early-stage bowel cancer also requires standardized resection of tumor, and the patient’s tumor is relatively early, so the effect after surgery is very good. Generally, the tumor of early stage bowel cancer is small and there is no lymph node metastasis, so regular checkups in the hospital are usually needed after surgical resection, and chemotherapy is generally not needed. For example, if the tumor appears in the right hemicolectomy, radical treatment of right hemicolectomy is usually performed; if the tumor appears in the left hemicolectomy, radical treatment of left hemicolectomy is performed; if the tumor appears in the sigmoid colon, radical treatment of sigmoid colon is performed; of course, at present, many hospitals adopt minimally invasive surgery, that is, radical treatment of colon cancer under laparoscopy.
