A new study suggests that dental X-rays increase the risk of brain tumors.  Researchers at Yale School of Medicine surveyed a group diagnosed with meningioma - the most common form of brain tumor - and a group without any brain cancer.  The results show the group with brain tumors were more than twice as likely to report ever having dental X-rays.

Experts note that it's likely the association is from past X-rays that had much higher levels of radiation than those used today.
