What should you know about lumps under chin and neck?

Under the chin, a lump may involve a lymph node, salivary gland, skin or soft tissue. Elsewhere in the neck, the thyroid and deeper lymph nodes can also be involved. Dental infection, throat infection, skin inflammation and cysts are possible causes. Persistent masses can also occur with Head and Neck Cancer, Lymphoma or Thyroid Cancer. The location and feel provide clues, but they cannot confirm the diagnosis.

Your clinician may ask about recent infections, dental pain, smoking or tobacco exposure, voice change, swallowing, ear symptoms and how the lump has changed. They may examine your mouth, throat, neck and thyroid, then arrange imaging or a needle sample if the findings require it.

Book an assessment if the lump remains, grows, becomes hard or fixed, or returns repeatedly. Do not squeeze it or start leftover antibiotics. Write down when you noticed it, any recent dental or throat illness, and symptoms such as fever or night sweats. Bring medication details to the appointment. Cancer of Unknown Primary may be considered only after investigations identify cancer without locating its starting point.

Use urgent services for trouble breathing or swallowing, rapidly expanding swelling, drooling, severe dehydration, facial weakness, confusion or uncontrolled bleeding. Arrange prompt medical review for persistent hoarseness, coughing blood, an ulcer in the mouth or skin, or unexplained drenching sweats. These symptoms require examination and do not prove that the lump is cancer.

Ask whether the lump seems to be a lymph node, salivary gland, thyroid or skin lesion. Ask which test is most suitable, whether a dental or throat source should be checked, how results will be explained, and when to return. If the thyroid is involved, ask whether Thyroid Removal Surgery is relevant.
