What should you know about a painless movable lump on the right side of the neck?

A lump that moves slightly under the skin may be a lymph node or a superficial cyst, while pain can occur when nearby tissue is inflamed. These clues are not enough to classify a lump: some harmless lumps are firm, and some serious conditions may not hurt. Head and neck cancer and lymphoma can present with neck swelling, but the lump is not evidence that either diagnosis is present.

A clinician will assess depth, size, borders, texture and movement, then check the throat, mouth, ears, skin and thyroid region. If the origin is not clear, imaging or a sample may be recommended. A cancer of unknown primary is a specialist diagnosis, not a label for an unexplained lump at first presentation.

Record when you noticed the lump and whether it changes after a cold or other illness. Compare its position without repeatedly pressing it, and note hoarseness, swallowing difficulty, ear pain, dental symptoms, fever, night sweats or weight change. Arrange a clinical appointment for a persistent or unexplained lump. Do not puncture it or use home remedies intended to make it disappear.

Seek urgent care for breathing difficulty, inability to swallow, rapidly increasing swelling, severe infection symptoms or sudden facial or neck swelling. Request prompt assessment if the lump becomes fixed, enlarges, is associated with persistent hoarseness or swallowing trouble, or remains after a nearby infection has settled. A lack of pain does not remove the need for follow-up.

Ask whether the mobility suggests a superficial structure, whether the lump needs imaging, and how its size or feel should be monitored. Ask which symptoms would change the urgency and whether an ear, nose and throat or oncology referral is appropriate.
