The short explanation
A painless swelling at the front of the neck is often an enlarged thyroid, called a goitre, and most goitres are not cancer. It is still worth having it examined, because the cause decides what, if anything, needs to be done. A general physician at a nearby hospital or PHC can examine it first and arrange blood tests and usually an ultrasound of the neck. You may be referred to an endocrinologist or ENT surgeon if needed.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Common causes include iodine deficiency, thyroid inflammation, an overactive or underactive thyroid, and lumps called nodules. Many goitres cause no symptoms and are found by chance.
- Tell the doctor how long the swelling has been there, whether it is growing, and whether you have symptoms such as weight change, a racing heart, tiredness or feeling cold.
- Iodised salt has made iodine-related goitre less common in India, but it still occurs, particularly where diets are limited.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what the swelling is. An examination, blood tests and often an ultrasound are needed, and occasionally a needle sample.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this my thyroid, and what is the likely cause?
- Do I need thyroid blood tests and an ultrasound?
- Does anything about it need a specialist?
- How will we know if it is growing?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 if a neck swelling makes it hard to breathe.
Get help the same day
- Get care the same day if the swelling is suddenly painful, rapidly growing, or makes swallowing difficult.
Book an appointment soon
- See a clinician within days if your voice has become hoarse or the swelling feels hard.
Raise it at a routine appointment
- Book a routine appointment for a painless swelling that has been there for a while.
