Lymph nodes are small, bean-shaped glands present throughout the body.
They are part of the lymph system, which carries the lymph fluid, nutrients, and waste substances between the body tissues and the bloodstream.

The lymph nodes filter lymph fluid as it passes through them, trapping bacteria, viruses, and other foreign substances, which are then destroyed by lymphocytes (special forms of white blood cells).

Rarely, certain cancers such as testicular cancer, lymphoma, or melanoma may produce a swollen lymph node in this region.
The lymph nodes that are above the collarbone (supraclavicular) may become ...
