Dental X-rays: Possible Cause of Meningioma

If you’ve had a meningioma brain tumor, like me, and are wondering why it ever happened to you, maybe we just learned a potential cause: dental X-rays.

According to a study from the Yale School of Medicine, published Tuesday in the American Cancer Society journal Cancer, “people with meningioma were more than twice as likely as people without the brain tumor to have had a bitewing X-ray sometime in their life. For a bitewing X-ray, the patient holds the film in place by biting down on a tab.”

I don’t know about you, but I’ve had a ton of bitewing X-rays in my life.

And, yes, this lends a whole new meaning to the phrase, “bite me.”

The article in The Washington Post went on to report that “Lead author Elizabeth Claus, professor at the Yale School of Public Health and a neurosurgeon at Brigham and Women’s Hospital in Boston, noted that risk factors for meningioma, the most commonly diagnosed form of brain tumor, remain poorly understood, in part because meningioma was only added to brain tumor registries in the United States in 2004.”

An ABC report notes that the level of radiation is less than a tenth of the level that is used today.

Hi there! I will be looking forward to visit your page again and for your other posts as well. Thank you for sharing your thoughts about meningioma. I am glad to stop by your site and know more about meningioma. Keep it up! This is a good read. You have such an interesting and informative page.
Ninety-two percent of meningiomas are benign, with 8% being either atypical or malignant.
Approximately 96% of meningiomas occur within the skull, with the remaining 4% involving the spinal column. Meningiomas are the most common type of primary brain tumor, accounting for 34.4% of all such tumors. A primary brain tumor originates from the brain, spinal cord or associated tissues (called the central nervous system or CNS), while a secondary brain tumor arises from cancerous cells that have spread (metastasized) to the CNS from elsewhere in the body.
