Causes, Risk Factors, and Prevention TOPICS

Can thyroid cancer be prevented?

Most people with thyroid cancer have no known risk factors that they can change, so there is no sure way to prevent most cases of this disease.

Radiation exposure, especially in childhood, is a known risk factor for thyroid cancer. Because of this, doctors no longer use radiation treatment for minor diseases. Imaging tests such as x-rays and CT scans also expose children to radiation, but at much lower doses. If there is an increased risk of thyroid cancer from these tests is likely to be small, but to be safe, children should not have these tests unless they are clearly needed..
