Early stage colon cancer is mainly treated by way of surgery, and if metastasis occurs, the symptoms are relieved by palliative surgery and radiotherapy. The radical treatment of early colon cancer is early resection of the mass, which can be treated by colonoscopy with mucosal resection, high-frequency electrocoagulation resection or mucosal dissection. For those who have extensive cancer metastasis and the diseased bowel segment is not resectable, palliative surgeries such as fistula are feasible to alleviate symptoms and improve patients’ quality of life. Systemic intravenous chemotherapy can be carried out after surgery for early stage colon cancer, and the main drugs include 5-fluorouracil and so on. Radiotherapy can also be used to kill tumor cells completely, which is applicable to a few early-stage patients and patients with special cell type sensitivity. If diagnosed with colon cancer, it should be treated timely under doctor’s guidance, and should not use medicine without authorization, so as to avoid delaying the condition. Pay attention to rest on weekdays, reasonably match the diet, and eat more crude fiber food and vegetables.
