Lymph Node Biopsy
(Biopsy, Lymph Node)
by Patricia Griffin Kellicker, BSN
Lymph nodes are found throughout the body. They are part of the body’s immune system. These nodes help fight infection by producing special white blood cells. They also work by trapping bacteria, viruses, and cancer cells. Normally, lymph nodes cannot be felt unless they are swollen.
