Fine Needle Aspiration Cytology of Neck Mass (FNA)

Why Is This Test Done?

Your healthcare provider may recommend this test if you have a persistent lump in your neck that doesn’t go away on its own. It’s often used to investigate causes like thyroid nodules, lymph node enlargement, or other suspicious growths. The test helps guide next steps, such as further imaging or treatment planning.

What Happens During the Procedure?

You’ll lie down comfortably while a healthcare professional uses a fine needle to extract cells from the lump. A local anesthetic may be used to numb the area. The procedure is quick and usually painless. Afterward, you may experience mild soreness or swelling, which typically resolves quickly.

What Does the Test Result Mean?

The results are reviewed by a pathologist, who examines the cells under a microscope. They may report whether the cells look normal or if they suggest abnormalities such as infection, inflammation, or cancer. Results can be qualitative (yes/no) or more detailed, depending on the complexity of the sample.

Common Conditions Evaluated

This test helps diagnose or monitor conditions like thyroid nodules, lymph node enlargement (often due to infections, inflammation, or cancer), salivary gland tumors, or other neck masses. It’s also used to assess suspicious lumps that don’t have obvious causes.
