What should you know about a localized swelling, mass or lump in the neck?

A neck lump may involve skin, muscle, a salivary gland, the thyroid, or a lymph node. Recent infection can make lymph nodes enlarge and become tender. A persistent, firm, fixed, or growing mass may need more detailed evaluation. A neck lump is a possible presentation of head and neck cancer, lymphoma, thyroid cancer, or cancer of unknown primary, but the lump alone cannot identify the cause.

A clinician may examine your mouth, throat, ears, thyroid and neck, then decide whether imaging, blood tests, or a sample from the lump is appropriate. The location, texture, duration and associated symptoms help guide that decision.

Arrange an appointment if the lump does not settle, returns, or changes. Note when it appeared, whether it is painful, and whether it changes during illness. Tell the clinician about hoarseness, swallowing difficulty, ear pain, night sweats, fever, weight change, or a history of smoking or previous cancer. Do not squeeze or repeatedly massage the area.

Assessment may include an ultrasound or another scan, followed by a needle sample when the findings call for it. Treatment depends on the cause; thyroid-related disease may sometimes lead to discussion of thyroid removal surgery.

Seek urgent medical help if swelling makes breathing or swallowing difficult, your voice changes suddenly, or the area becomes rapidly larger with severe pain or fever. Emergency care is also appropriate for choking, bluish lips, or sudden weakness. These warning signs require prompt attention regardless of whether the lump is new or longstanding.

Ask what structures could be causing the lump, whether its position or texture changes the evaluation, and which symptoms should prompt faster review. You can also ask whether imaging or sampling is needed and when you should expect the next update.
