Needle biopsyĪ needle biopsy removes a small sample of cells from your lymph node. There are three ways to perform a lymph node biopsy. Once the doctor removes the node or sample, they send it to a pathologist in a lab, who examines the lymph node or tissue sample under a microscope. With a lymph node biopsy, your doctor may remove the entire lymph node, or take a tissue sample from the swollen lymph node. It’s typically an outpatient procedure, which means you don’t have to stay overnight at the facility. This test will help your doctor look for signs of a chronic infection, an immune disorder, or cancer.Ī lymph node biopsy can take place at a hospital, in your doctor’s office, or in other medical facilities. If your lymph nodes remain swollen or grow even larger, your doctor may order a lymph node biopsy. However, to rule out other problems, your doctor may monitor and check your swollen lymph nodes. Swollen lymph nodes that result from minor infections or insect bites typically don’t require medical care. Your doctor may find swollen or enlarged lymph nodes during a routine examination. Swollen lymph nodes can appear as a lump beneath your skin. A lymph node may swell in response to an infection somewhere in your body. Lymph nodes are part of your immune system, and they help your body recognize and fight off infections.

They’re found close to internal organs such as your stomach, intestines, and lungs, and are most commonly noted in the armpits, the groin, and the neck. Lymph nodes are small, oval-shaped organs located in different parts of your body. A lymph node biopsy is a test that checks for disease in your lymph nodes.
