Guide To The Causes Of Swollen Lymph Nodes

The lymphatic system is the part of the body that circulates lymphatic fluid. The lymph nodes act as the filtration system for this part of the body. They also store white blood cells, which are part of the immune system, and kill invading pathogens. When individuals have a tumor or an infection, the lymph nodes swell. When abnormal or diseased cells, bacteria, and viruses pass through the lymphatic system, the lymph nodes stop them from circulating to other parts of the body. If the body is fighting an illness or infection, the lymph nodes catch debris.

Swollen lymph node treatment varies based on the condition causing it.
