What should you know about a lump near your neck and collarbone?

A lump in this area may be a skin cyst, an inflamed tissue area, or an enlarged lymph node. Lymph nodes can react to infections in the chest, throat, skin, or arm. A lump near the neck and collarbone is a presentation of lymphoma, head and neck cancer, thyroid cancer, or cancer of unknown primary in some people; location alone cannot establish the cause.

Note which side it is on, whether it is tender or fixed, and whether it changes in size. Record recent infections, dental problems, skin wounds, cough, chest symptoms, fever, night sweats, or unexplained weight loss. Do not press or puncture the area.

Arrange a prompt appointment for a lump above or below the collarbone, especially if it remains or enlarges. A clinician may examine the neck, chest, breast or arm regions, mouth, throat, and thyroid. Depending on the findings, imaging or a needle sample may be recommended. Bring your symptom timeline and details of any recent infection or injury.

Seek urgent help for difficulty breathing or swallowing, rapidly increasing swelling, severe pain, or fever with spreading redness. Arrange prompt review for a firm or fixed lump, persistent cough or hoarseness, unexplained weight loss, drenching night sweats, or swelling in more than one area.

Ask which tissue may be causing the lump, whether its collarbone location changes the assessment, and which test is most useful. Ask how results will be explained, when follow-up should occur, and which symptoms should lead you to seek earlier care.
