Thyroid nodules: which doctor should I see?
Thyroid nodules are common and in most cases benign. They are often found by chance on an ultrasound or as a lump at the base of the neck. Here you will learn what may be behind them, when it is urgent and which specialist to see.
Book a specialistWhen it is urgent
- You find it hard to breathe.
- Your breathing makes a wheezing or other noise.
- You cannot swallow even your saliva.
With these signs, seek emergency help — call 112 or go to the nearest emergency department.
Call 112What it may mean
- Benign nodules or cysts — the most common finding.
- Autoimmune inflammation of the thyroid (Hashimoto’s) — sometimes with tiredness, weight gain and dry skin.
- Lack of iodine — less common today.
- A nodule that makes hormones — palpitations, sweating and weight loss.
- Rarely, a malignant change — which is why a nodule is monitored and, when needed, tested.

How to prepare for the visit

Frequently asked questions
Are nodules dangerous?
Most are not. Book a visit without delay if the lump grows, is hard and does not move, or you have hoarseness or difficulty swallowing that does not pass. After an ultrasound and tests the endocrinologist judges whether monitoring or a needle biopsy is needed.
Which tests will I need?
Usually a thyroid hormone test and an ultrasound.
How often should they be checked?
It depends on the type of nodule. The doctor will tell you when to come back.
