For swollen lymph nodes due to non-specific infection with bacteria, such as lymphatic tuberculosis, anti-tuberculosis treatment should be administered for the cause, and the swollen lymph nodes may be restored to normal. For lymphoma caused by the hematological system or malignant lymph node metastasis, it is best to find the primary lesion of the disease and to provide systematic radical treatment for the primary tumor, which may change the degree of lymph node enlargement through radiotherapy.
