What are the symptoms?

Thyroid cancer usually develops slowly, without many obvious symptoms. However, some people experience one or more of the following:

  • a painless lump in the neck (the lump may grow gradually)
  • trouble swallowing
  • difficulty breathing
  • changes to the voice, e.g. hoarseness
  • swollen lymph glands (lymph nodes) in the neck (the lymph nodes may slowly grow in size over months or years).

Although a painless lump in the neck is a typical sign of thyroid cancer, thyroid lumps (nodules) are common and turn out to be benign in 90% of adults.

Having an underactive or overactive thyroid (hypothyroidism or hyperthyroidism) is not typically a sign of thyroid cancer.

Which health professionals will I see?

Your general practitioner (GP) will arrange the first tests to assess your symptoms. If these tests do not rule out cancer, you will usually be referred to a specialist, such as an endocrinologist or endocrine surgeon. The specialist will arrange further tests.

If thyroid cancer is diagnosed, the specialist will consider treatment options. Often these will be discussed with other health professionals at a multidisciplinary team (MDT) meeting. During and after treatment, you will see a range of health professionals who specialise in different aspects of your care.
