Early stage colon cancer has a greater hope of cure. Early stage colon cancer patients prefer open surgery or laparoscopic surgery for resection, if the resection is clean, it can achieve the purpose of radical cure, and the five-year survival rate of patients can be as high as 80%, and most patients can obtain clinical cure. If close monitoring and follow-up are done after surgery, or appropriate adjuvant treatment is given, the chance of cure will be even higher. Colon cancer is one of the common gastrointestinal malignancies. Early colon cancer refers to colon cancer in situ, that is, cancer cells are confined to the mucosal layer of the colon and do not break through the basement membrane, or the cancer breaks through the basement membrane but does not break through the intestinal wall, while there is no regional lymph node metastasis. Unfortunately, most of the early stage colon cancer has no obvious symptoms, which is hard to attract patients’ attention, and by the time they visit the doctor because of discomfort, it has already developed to middle and late stage, and the chance of cure is very small.
