Lymph Node Biopsy
Alternate Names : Biopsy - Lymph Nodes
Definition
Lymph node biopsy is a test in which a sample of lymph tissue is removed for study.
The lymphatic system is made up of lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell, produce more white blood cells, and attempt to trap the organisms that are causing the infection. The lymph nodes also try to trap cancer cells.
In this test, a lymph node or a piece of a lymph node is removed for examination under a microscope.

Why is the Test Performed?
The test is used to help determine the cause of lymph node enlargement (swollen glands). It can also determine whether tumors in the lymph node are cancerous or noncancerous.
