In most cases a lump in the neck that goes away soon is a reaction in a gland following inflammation. Lumps in the head and neck region that persist may represent a medical condition such as a benign or malignant tumour needing a specialist ENT review.
There are numerous causes for lumps that persist in the Head and Neck region. Depending on their location and appearance these lumps may warrant further investigations ordered by your ENT Surgeon. In most cases a thorough assessment including a detailed history and careful examination will determine the need to further investigate.
Surgery is saved for cases where the lump causes significant discomfort or when there is a risk for a malignant tumour.
