It does not matter if the lymph node hyperplasia is caused by inflammation, but it is more troublesome if the lymph node hyperplasia is caused by specific infection or tumor. 1. Inflammation: Lymph node hyperplasia is a common clinical manifestation, mostly caused by inflammation, such as pharyngitis, which leads to lymphatic hyperplasia or lymph node enlargement in the throat, with the control or dissipation of inflammation, the hyperplasia or enlarged lymph nodes will generally return to normal. Chronic lymphadenitis is often mild and can be cured with prolonged anti-infection treatment. 2. Specific infections: Specific infections such as Mycobacterium tuberculosis can also lead to localized lymph node hyperplasia and enlargement, which are more serious. These cases are more serious and require regular use of anti-tuberculosis drugs such as isoniazid and rifampicin for several months before the enlarged lymph nodes slowly recover. These drugs should be taken under the guidance of a doctor. 3. Tumor: When lymphoma, lymphoblastic leukemia or other malignant tumors with lymphatic metastasis, resulting in lymph node hyperplasia, then the condition is serious, need timely and effective active treatment, and can be life-threatening.
