Intestinal cancer, including small and large intestine cancer, can be cured if the stage is not too late. Of course, small intestine cancer is more difficult to diagnose, and the early symptoms are not typical, so most of them are found at a later stage, which makes treatment more difficult, but surgery is the main treatment. Small bowel cancer is more often treated by pancreatic and duodenal resection, and small bowel resection. Colorectal cancer includes colon cancer and rectal cancer, which can be diagnosed through colonoscopy and pathological examination. Generally, radical surgery, including lymph node dissection, is followed by adjuvant chemotherapy, at least 4-6 courses, and some adjuvant radiotherapy to control the development of the disease. If there is no recurrence for more than 5 years, it is considered clinically cured, that is, cured, but it is not certain that there will be no recurrence after 5 years, and after 5 years, it should be reviewed once a year, while treatment.
