Neurosurgeons from the U.S. found that patients with a form of brain cancer in their lifetime were twice as likely to have dental X-rays than those who have such tumors were found.

A team of researchers from Yale University under the guidance of Professor Elizabeth Klaus has studied the data in 1443 patients with meningioma aged 20 to 79 years, starting in 2006. As a control group were 1350 healthy people.

The researchers found that patients with meningioma were a form of x-ray of the teeth twice as often as the control group. The survey which took place at least once a year, patients in the 1.4 - 1.9 times more frequently suffered from the disease.

An even greater risk of developing cancer were patients who at least once a year, did an X-ray of your mouth. They have encountered the disease three times more likely if the first such study done to them 10 years, the risk of developing cancer increased 4.9 times.

According to current recommendations for dentists accepted in the United States, X-rays of the teeth should be performed every 1-2 years to children, young people - in 1.5-3 years, adults - once in 2-3 years. According to Professor Claus, "the modern radiological equipment a person receives less radiation dose compared to what it was before. However, we recommend that physicians and patients more accurately relate to the appointment of such studies and make them only when really necessary."

The research is published in the issue of the scientific journal Cancer, released April 10.

Recall that in May last year, scientists from the World Health Organization said that cell phones can cause brain cancer in humans.
