Clinical information

When healthcare professionals speak of a neck mass, they refer to lumps or swelling in the neck. These lumps and swellings can appear anywhere on the neck and vary in shape and size.

Some neck masses are benign, meaning, even if they are considered an abnormal finding they're not a cause for concern and may disappear in time, but some are malignant and a healthcare provider should perform a physical exam, take a medical history, and order diagnostic imaging to assess.

Any number of things could cause neck masses. Some masses are congenital and can be removed immediately to prevent potential infections. Some are caused by the following:

Cysts
Thyroid nodules
Enlarged lymph nodes
Sarcoidosis
Neck trauma/injuries
Salivary gland tumors
Bacterial infections
Cancer

Commonly asked questions

The most basic way to prevent neck masses is by practicing good hygiene, but prevention isn’t guaranteed, given that neck masses can form because of an underlying condition. Getting regular check-ups should determine the cause, and preventive measures and treatment (depending on the cause) can prevent masses from becoming larger and problematic.

Yes. Even if some neck masses are benign, a person should see a doctor when they notice a mass that remains even after two or three weeks. If it becomes painful and/or starts growing rapidly, that’s a cause for concern.

They will conduct physical examinations, imaging tests, and biopsies to confirm the cause and determine if the masses are benign or malignant.
