Cancer belongs to malignant tumors, and there is no way to cure itself. In this case, further comprehensive anti-tumor treatment may be needed, including some early ones, which can be extended by radical resection, including lymph node dissection and so on. After surgery, local radiotherapy can be used to prevent local recurrence, and systemic intravenous chemotherapy can be used to control distant metastasis. In this case, it is possible to have no recurrence for more than 5 years, which is considered to be a clinical cure. However, this is also achieved through medication and surgery, and it is not possible for the patient to recover without any treatment. Cancer is also a consumptive disease, consuming more than normal, if the nutrition can not keep up, the cancer may also have explosive spread, metastasis, so diet and nutrition are also very important.
