Quick answer
What is Thyroid nodules?
Thyroid nodules are lumps that form within the thyroid gland at the front of the neck. They are very common, especially with increasing age, and the great majority are non-cancerous (benign).
- How it is treated: Management depends on the results of assessment.
- Self-care: There are no specific lifestyle measures for thyroid nodules, but attending assessment and any recommended monitoring, and reporting a growing lump, difficulty swallowing or breathing, or symptoms of an over- or underactive thyroid, all support good care.
- When to seek help: See a GP about a lump in the neck, so it can be assessed.
What it is
Thyroid nodules are lumps that form within the thyroid gland at the front of the neck. They are very common, especially with increasing age, and the great majority are non-cancerous (benign). Many cause no symptoms and are found by chance during examination or a scan; some are noticed as a lump in the neck. Occasionally a nodule produces thyroid hormone and causes an overactive thyroid, or a large nodule presses on nearby structures causing swallowing or breathing discomfort. Because a small proportion of nodules can be cancerous, they are assessed to check this, particularly if they have certain features or are growing. Assessment usually includes examination, thyroid blood tests, an ultrasound scan, and sometimes a needle sample (biopsy) from the nodule.
How it is treated
Management depends on the results of assessment. Most nodules are benign and, if they cause no symptoms and thyroid function is normal, they are simply monitored, sometimes with a repeat scan over time. A nodule producing too much thyroid hormone is treated like an overactive thyroid. Large nodules causing pressure symptoms, or nodules found or suspected to be cancerous, may be treated with surgery, and thyroid cancer is managed by a specialist team. A biopsy result guides whether treatment or monitoring is appropriate. The key reassurance is that most thyroid nodules are harmless, but assessment is worthwhile to confirm this and to check thyroid function.

Beyond medication
Lifestyle and self-care
There are no specific lifestyle measures for thyroid nodules, but attending assessment and any recommended monitoring, and reporting a growing lump, difficulty swallowing or breathing, or symptoms of an over- or underactive thyroid, all support good care.
When to get help
When to see a doctor
See a GP about a lump in the neck, so it can be assessed. Seek prompt assessment for a rapidly growing neck lump, difficulty swallowing or breathing, a hoarse voice, or symptoms of an over- or underactive thyroid.

Answers
Thyroid nodules: frequently asked questions
Are thyroid nodules cancer?
The great majority of thyroid nodules are non-cancerous. A small proportion can be cancerous, which is why they are assessed — usually with an ultrasound and sometimes a needle sample — to confirm they are harmless.
Do thyroid nodules need treatment?
Often not. Benign nodules causing no symptoms and with normal thyroid function are usually just monitored. Treatment is considered for nodules that overproduce hormone, cause pressure symptoms, or are cancerous.
