Dental X-Rays Possible Link to Brain Tumors

A new warning this morning about dental X-rays.

A study published in the journal "Cancer" shows a link between frequent X-rays and developing a certain brain tumor called meningioma.

Researchers found patients who had bitewing x-rays at least once a year had a 40 to 90 percent greater risk of the tumor.

They say this doesn't mean you should stop going to the dentist, nor does it prove x-rays cause tumors.

They do say annual X-rays put you at greater risk.

American Dental Association guidelines say healthy adults without cavities should get a dental x-ray once every two or three years.

Meningiomas are the most frequently diagnosed brain tumor among adults.
