Symptoms of thyroid cancer
The most common symptom of thyroid cancer is a painless lump in the neck that gradually gets bigger. Most thyroid lumps are benign (non-cancerous).
In most people, thyroid cancer develops very slowly. The most common symptom of papillary or follicular thyroid cancer is a painless lump in the neck that gradually gets bigger. Most thyroid lumps are benign (non-cancerous).
Other symptoms include:
- a hoarse voice, for no obvious reason, that doesn’t go away after a few weeks
- difficulty swallowing – a thyroid tumour pressing on the gullet (oesophagus) can cause this
- difficulty breathing – a thyroid tumour pressing on the windpipe (trachea) can cause this
- pain in the front of the neck.
You should see your doctor as soon as possible if you notice:
- a lump in your neck, whether it is painful or not
- any of the other symptoms above.
These symptoms can be caused by conditions other than cancer.
