What Is the Cause of Thyroid Cancer?

Experts do not know the exact cause of thyroid cancer but they know that people who have been exposed to high doses of radiation – whether from medical treatment or from the environment – were more likely to develop thyroid cancer. Dental imaging from one period to another does not increase the risk of thyroid cancer, but previous radiotherapy in the head, neck or chest (especially during childhood) may increase the risk of thyroid cancer. Radiology has been used since the 20th to 50s to treat problems such as acne and bloated almonds, but this method is no longer used to treat non-cancerous conditions.
