It is possible to remove the swollen lymph nodes, but the cause of the swollen lymph nodes should be clarified before treatment. If it is a localized swollen lymph node due to inflammatory stimulation or allergy, removing the lymph node alone cannot solve the cause, so the primary disease should be treated, and the swollen lymph nodes will naturally subside when the primary disease is relieved. In addition, swollen lymph nodes can also be seen in the metastasis of malignant tumors. When the swollen lymph nodes are caused by the metastasis of malignant tumors, the swollen lymph nodes should be removed in addition to the resolution of the primary lesion. Prophylactic debridement of the surrounding lymph node sites that may take the lead in metastasis, followed by postoperative radiotherapy and chemotherapy to remove the cancer cells that may be present in the blood. In addition, patients with chronic fever may have abnormally enlarged lymph nodes, and similar patients have been encountered in clinical practice, when lymph node removal followed by biopsy can also be done.
