New study warns of brain tumors by mobile much telephony

Bordeaux (France) – Is increased mobile phone radiation associated with an increased risk of brain tumors? Despite numerous studies, this question is controversial to this day, as there are different results. The results of a recent study by French scientists now joins the list of reminders and shows that it’s a question of how much you make a phone call. According to the conclusion, there is a connection between high-telephony and brain tumors.

As the researchers Gaelle Coureau and Ghislaine Bouvier of the Université Bordeaux Segalen currently report in the journal “Occupational and Environmental Medicine” (DOI: 10.1136 / oemed-2013-101754), they examined 253 cases of glioma patients and 194 meningioma patients between 2004 and 2006, as well as a control group of 892 representative normal persons.

According to the study, a statistically verifiable correlation with the development of brain tumors of both species and extreme high-frequency telephony is indeed emerging . According to the researchers, the vulnerable risk group includes people who have been on the phone for more than 900 hours, made more than 18,000 calls, or spent more than fifteen hours per month over five years. The risk of this group of people with a brain tumor The scientists estimate that they are two to threefold compared to the members of the control group. The risk also increases with professional groups who make frequent calls in the urban environment. The study also found a connection between the position of the mobile device held at the temple area and the tumors that were formed.

Thus, the French study confirms previous studies, mainly from Scandinavian countries, which suggest a link between brain tumors and the use of mobile phones – especially in the case of frequent callers.

At the same time, however, the French researchers also agree with the earlier findings that “normal” use of mobile devices does not pose a generally increased risk. It also remains to be examined whether the radiation emanating from the terminal equipment, which has always been reduced with the further development since 2006, is accompanied by a correspondingly decreasing risk.

In principle, even authors of studies that have not yet found an increased risk due to “mobile phone radiation” recommend reducing their use as much as possible and, if possible, also reducing the radiation exposure by using headsets.
