Tumours of the Lymph Nodes

A lymph node is a small (usually <1cm) oval organ of the immune system. Lymph nodes are scattered widely throughout the body and are linked by lymphatic vessels. Lymph nodes contain immune cells and act as filters of foreign particles.

Lymph nodes enlarged in a spectrum of conditions ranging from a trivial throat infection to a life-threatening cancer. The degree of cancer spread to the lymph nodes used for cancer staging, which guides treatment and is used to prognosticate.
