The lymphatic system is part of the body’s immune system that fights disease and infections. Lymph nodes are tiny, bean-shaped organs that help destroy infectious germs such as viruses and bacteria.

Lymphadenopathy occurs when lymph nodes in a specific area of the body (such as the head, neck, armpits, groin, abdomen or chest area) or throughout the whole body become enlarged.
