Distant lymph node metastasis can be seen in many kinds of malignant tumors, and appropriate treatment methods should be chosen according to the type of primary tumor and the specific conditions of patients. 1. radiotherapy: radiotherapy is the method of using radiation to treat tumors, a large amount of radiation can destroy the cell chromosomes, causing the cells to be unable to grow normally and controlling the division of cancer cells, which is effective in treating distant lymph node metastasis caused by malignant tumors. 2. Chemotherapy: Chemotherapy refers to the use of chemical drugs to destroy cancer cells, so as to achieve the purpose of treatment. For distant lymph node metastasis caused by malignant tumors, oral or intravenous chemotherapeutic drugs can be used, which are systemic in nature and are the main therapeutic means at present. The adoption of chemotherapy drugs needs to be decided according to the primary tumor. 3. Targeted therapy: Targeted therapy refers to the use of drugs to purposefully target the cancer-causing points for treatment, so as to make the tumor cells die, and try not to affect the normal cells around the tumor. Due to distant lymph node metastasis caused by malignant tumors, targeted therapy can target the primary lesions for targeted treatment. 4. Surgery: For the metastatic lymph nodes with obvious enlargement and compression, surgical resection can be chosen. Since distant lymph node metastasis can be seen in many kinds of malignant tumors, it is recommended that patients seek medical treatment in time and follow the doctor’s instructions.
