X-rays of the teeth increase the risk of brain tumors in two or even three times as the researchers found. It's enough to make these pictures more than once a year.
Who has not encountered such a seemingly typical situation. Before starting treatment with a dentist you do X-ray . But it turns out not entirely successful, and do again, and then again and again. A week later, the picture is repeated at the end of treatment do another. The doctor assures you that no danger of these microscopic doses of radiation are not for you.
However, researchers at Yale School of Medicine and medical centers in the United States Brigham and Women's Hospital in Boston found that people who have more than once a year pass through X-rays teeth often subsequently developed meningioma - one of the varieties brain tumors . Fortunately, this non-aggressive form of cancer that grows very slowly. But meningioma can also be fatal, as it causes a pressure on the brain.
Researchers drew attention to two types of X-ray images - bite and panoramic. It turned out that people who passed through the panoramic x-ray more than once a year, brain tumor It developed in 2, 7-3 times more likely than those who did not make shots. The probability of cancer increases with age.
And among those who made frequent pictures with bite X-rays, the risk of developing meningioma grew by 40-90%. We note that earlier scientists have proven - 10 X-rays of the teeth increase the risk of thyroid cancer five times.
