Bowel cancer is a relatively common malignancy, which includes rectal cancer and colon cancer. Its incidence rate in descending order is rectum, sigmoid colon, cecum, ascending colon, descending colon and transverse colon. The incidence of bowel cancer is related to many factors, including lifestyle, diet, genetics, colorectal adenoma, etc. The treatment of bowel cancer should be early and the early cure rate is higher. Analysis of treatment methods of intestinal cancer 1.Surgical treatment The only radical treatment method of intestinal cancer is to remove the cancer at an early stage. If metastasis of intestinal cancer is found in the investigation, but the diseased bowel curvature can still be free, in principle, the colon cancer should be removed to avoid intestinal obstruction in the future; on the other hand, the cancerous tumor of intestinal cancer often has erosion, blood oozing or secondary infection, so the general condition can be improved after removal. 2.Chemotherapy After radical surgery of intestinal cancer, about 50% of patients with intestinal cancer still have recurrence and metastasis, mainly because the hidden metastases are not detected before surgery or the lesions are not completely removed during surgery. Therefore, this is also a kind of treatment for colon cancer. 3.Cryotherapy Cryotherapy in the treatment of bowel cancer adopts refrigerant liquid nitrogen, and after fully exposing the tumor through anoscope, the cannonball type freezing head of different sizes is selected to contact the tumor tissue, which can effectively kill and destroy the tumor tissue of bowel cancer. It can reduce patient’s pain and avoid making artificial anus, and can achieve satisfactory curative effect with chemotherapy.
