The axillary lymph nodes become smaller in review may be improving, and should be reviewed regularly. It may also be caused by lymphatic tuberculosis and malignant tumor. 1. If it is caused by infection, after controlling the infection through drugs such as cefradine, levofloxacin, ciprofloxacin, etc., the lymph nodes will have clear boundaries and become smaller in size. It is important to have regular checkups and actively cooperate with the treatment to ensure that the body is cured. 2. If it is caused by lymphatic tuberculosis or malignant tumor, and the lymph node boundary is not clear during examination, it may be the deterioration and fusion of lymph nodes, resulting in gradual shrinkage of lymph nodes. Lymphatic tuberculosis can be treated with drugs such as isoniazid, rifampicin and pyrazinamide. Malignant tumors, on the other hand, can be treated by performing radical resection surgery. Therefore, patients with axillary lymph nodes that have become smaller on review should have the cause of the disease clarified as soon as possible and be treated after diagnosis.
