Whether bowel cancer can be cured or not is related to many factors, not only involving the biological characteristics of tumor, but also whether it can be completely cured is inseparable from early diagnosis and staging, treatment methods and other factors. Generally speaking, if bowel cancer is detected early, there is no local spread or distant metastasis, and the lesion is confined to the local area, timely surgery can be performed under colonoscopy, and the 5-year survival rate of patients who can reach the standard of complete colonoscopic resection is as high as 95%. A portion of those who cannot be resected colonoscopically can be surgically resected, and according to the stage and type, with chemotherapy after surgery, there is also a chance of complete cure. 2.After treatment, we should also be prepared to prevent recurrence. Regular monitoring of colon cancer recurrence, such as colonoscopy, abdominal ultrasound and CT, as well as some blood monitoring indexes, can detect the recurrence area at an early stage and carry out relevant treatment, so that long-term survival can be achieved. 3.If intestinal cancer is found late, with heavy local infiltration, extensive metastasis, or intestinal obstruction at the time of consultation, or complications such as intestinal bleeding, perforation, septic peritonitis, etc., surgical treatment can no longer be removed, and only maintenance treatment or symptomatic treatment can be carried out, which is more difficult to cure. 4. In recent years, with the progress of medical research, new drugs for advanced tumors have been introduced, so that some of the colon cancer patients who had no chance of long-term survival in the past have the possibility to be cured. If treated timely in early stage, colon cancer may still be cured, the key is early diagnosis and early treatment.
