The exact cause of thyroid cancer in most people is unknown. Some risk factors can increase your chance of developing it.
Remember an overactive or underactive thyroid does not increase your risk of developing thyroid cancer. If you think you may be at risk, first talk to your family doctor (GP) about your concerns. He or she may advise you to visit a specialist.
