Question: are all lumps in neck cancerous?
Answer: A lump in the neck that lasts more than two weeks should be seen by a physician as soon as possible. Of course, not all lumps are cancer. But a lump(s) in the neck can be the first sign of cancer of the mouth, throat, voice box (larynx), thyroid gland, salivary glands, or of certain lymphomas and blood cancers.
