What causes thyroid cancer?

The cause of thyroid cancer, as with other cancers, is due to damage to cellular DNA. This damage results in uncontrolled growth of abnormal cells, which leads to formation of a cancer. The damage to thyroid cells can be from a number of causes, such as inherited gene mutations or exposure to radiation; however, many causes of thyroid cancers still remain unknown.
