X-rays increases the probability of brain cancer

Scientists from Yale University, led by Professor Elizabeth Klaus found that people suffering from brain cancer, during his life did more x-rays of teeth than healthy people.

Only the study involved 1443 volunteer with meningioma, a tumor of the cells of the arachnoid mater. The age of the subjects ranged from 20 to 79 years. For control group, the researchers scored 1350 healthy people.

It turned out that cancer patients had x-rays of the teeth 2 times more often than people in the control group. Interestingly, x-ray of jaws cancer risk was increased in three times.

Scientists do not deny that this method of diagnosis is required in dentistry and to refuse it is impossible, however, x-rays should be applied strictly on the evidence and without exceeding the allowable radiation dose.
