When to worry about a neck lump if you have head and neck cancer

Neck Lump is a very common presentation of Head and Neck Cancer. It may reflect an involved lymph node or a growth in the neck, throat, mouth, thyroid, or nearby tissues. Infection and other non-cancer causes can also produce swelling. The location and texture are useful clues, but touch alone cannot identify the cause. A specialist may examine the mouth, throat, ears, and neck, then use imaging or a needle sample to assess the lump. In someone already receiving cancer care, a new or changing lump may represent treatment-related inflammation, infection, recurrence, or another problem.

Contact your cancer team or arrange a medical review for a new, persistent, or growing neck lump. Record when you noticed it, whether it is painful or mobile, and any change in swallowing, speech, hearing, breathing, or mouth symptoms. Avoid squeezing it or delaying review while waiting for it to become painful. Bring your treatment dates, medicine list, and previous scan information. The clinician can decide whether examination, imaging, a scope examination, or tissue sampling is needed.

Seek prompt advice for a lump that enlarges, feels hard or fixed, persists after an infection settles, or comes with hoarseness, one-sided ear pain, mouth bleeding, a non-healing sore, or difficulty swallowing. Get emergency help for breathing difficulty, rapidly worsening swelling, inability to swallow saliva or liquids, coughing blood, or sudden severe weakness. Tell the team about these symptoms clearly so airway and treatment needs can be assessed without delay.
