Lymphadenopathy

Lymph node enlargement refers to lymph nodes in the submandibular, axillary, groin, etc., which are enlarged by bacteria and toxins when they are inflamed and can be clearly touched by hand, often accompanied by pain. The causes are many. When an infection occurs in a part of the body and the bacteria pass through the lymph nodes with the lymph fluid, it can cause the swelling and pain of the lymph node group accordingly. When the body suffers from a malignant tumor, it often metastasizes along the lymphatic vessels and stays in the lymph nodes to divide and proliferate, which causes the lymph nodes to swell.
