What is thyroid cancer?

Thyroid cancer is when abnormal cells in the thyroid gland start to divide and grow in an uncontrolled way. 

Symptoms of thyroid cancer

The symptoms of thyroid cancer include a lump in your neck, a hoarse voice, a sore throat or difficulty in swallowing. 

Risks and causes of thyroid cancer

Some factors might increase your risk of developing thyroid cancer. This doesn’t mean that you will definitely develop thyroid cancer if you have any of them.

Getting diagnosed

Your GP will ask about your symptoms. They'll decide whether to refer you for tests or to a specialist. 

Stages and types

There are different types of thyroid cancer. The stage of a cancer tells you its size and whether it has spread. It helps your doctor decide which treatment you need. 

Treatment

Your treatment depends on the type of thyroid cancer, how big it is and whether it's spread anywhere else in your body.
