Lymph node enlargement can be a symptom of many different diseases such as infections, drug hypersensitivity, rheumatic diseases and cancers. The underlying cause may be a viral disease that does not require treatment, or a lymph cancer that will require chemotherapy treatment. Therefore, when lymph node enlargement is noticed, the underlying cause should be investigated.
How to Understand the Cause?
In order to investigate the cause of lymph nodes, an appropriate physical examination, laboratory tests, peripheral blood smear examination and imaging methods should be performed according to the patient’s age, disease history, medications, lymph node size, duration, location and accompanying symptoms.
