2The Causes of Swollen Lymph Nodes

The swollen lymph node is a sign of a bacterial or viral infection. In rare cases, cancers and immune system disorders can result in swollen lymph nodes as well. Different lymph nodes are responsible for the filtration of the lymph fluid in different parts. Therefore, the swelling sites can help doctors trace the problems, identify the underlying causes, and give specific interventions. For instance, the swollen lymph node in the neck is a common indication of an upper respiratory infection, and sexually transmitted infections or skin infections might trigger swollen lymph nodes in the groin. We have rounded up some possible causes below for your reference. [1]
