The short explanation
A swelling at the front of the neck that moves up when you swallow is often the thyroid. An enlarged thyroid is called a goitre, and lumps within it are called nodules. Both are common in women and most nodules are not cancer, but a new neck lump should be examined, usually followed by a blood test and an ultrasound. In parts of India, goitre has historically been linked to iodine deficiency, which iodised salt has reduced a great deal; today many goitres have other causes.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A goitre can occur with an underactive, overactive or normally working thyroid, so a blood test is needed to know which. Ultrasound features decide whether a nodule needs a fine-needle sample. Swollen glands (lymph nodes) from a throat infection feel different and usually settle within a few weeks.
- A family history of thyroid cancer or previous radiation to the neck are worth mentioning.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether your swelling is the thyroid, a gland, or something else, and it cannot tell you whether a nodule is harmless. Those need examination and usually an ultrasound.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this my thyroid, and does it need an ultrasound?
- How is my thyroid working, according to the blood test?
- Does this nodule need a needle sample, and why?
- How will we keep an eye on it?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
- Get emergency care now (call 112 or 108) for difficulty breathing or a neck swelling that is growing quickly with trouble swallowing.
- See a clinician within one to two weeks for any new neck lump, particularly one that is hard, growing, or comes with a hoarse voice lasting more than three weeks.
