In short
The usual sign of thyroid cancer is a painless lump in the front of the neck. A hoarse voice that does not settle, or trouble swallowing, also needs a GP visit. About 4,500 people are diagnosed in the UK each year.
The thyroid sits at the base of the neck. Lumps here are common. Ultrasound and a needle test are how doctors tell a cyst from a cancer.
Which neck changes should you report?
A lump you can see or feel in the front of the neck is the main reason people are referred. Pain is not required.
- A painless lump in the front of the neck that is growing
- A hoarse voice that does not get better
- Difficulty swallowing or breathing
- A neck swelling that lasts more than a few weeks
Are most thyroid lumps cancer?
No. Many are benign nodules or cysts. The reason to check is that the lumps that are cancer are highly treatable when found.
Does thyroid cancer run in families?
Most cases are not inherited. A few rare types are linked to family syndromes. Mention any family history of thyroid cancer or endocrine tumours to a GP.
What are the key takeaways?
- A new or growing front-of-neck lump should be checked.
- Most thyroid lumps are not cancer.
- Common types have excellent long-term survival.
Care like this is out of reach for millions
The diagnosis, screening and treatment described here are routine in the UK. In Pakistan, Indonesia and Malaysia, poverty puts them out of reach — so a treatable cancer too often becomes a fatal one. World Aid Network funds treatment through locally-licensed oncologists for patients who cannot pay.
Frequently asked questions
Can a GP tell if a neck lump is cancer?
Not by feel alone. Ultrasound and, if needed, a needle sample are the next steps.
Does a normal blood test rule out thyroid cancer?
No. Thyroid hormone blood tests can be normal. Imaging is what looks at a lump.
Do you fund thyroid surgery overseas?
When a partner hospital recommends it for a patient who cannot pay, within cancer programme capacity.
