Early intestinal cancer is not a terminal disease, but it can be cured if diagnosed and treated early. At present, the five-year survival rate of rectal cancer has increased from 50% to 70%; The 5-year survival rate of colon cancer increased from 70% to 80%. Surgery is the first choice for treatment. Surgical resection should be done as much as possible after the diagnosis of intestinal cancer. If the lesion has not spread, surgical resection may have a satisfactory result.
