The chronic fears that the use of mobile phones may increase the risk brain tumor revived in recent years after their appearance fifth generation (5G) wireless networks. But a big new one British scientific study reassures concluding that cell phone users do not have an increased risk of brain cancer.
Mobile phones are transmitting radio frequency waves which, if absorbed by the body’s tissues, can raise their temperature and cause damage. Because cell phones are usually held close to the head, the emitted waves reach a depth of a few centimeters in the brainsomething that has for years led to concerns about the potential risk of developing brain tumors.
THE International Agency for Research on Cancer (IACR) has characterized radio frequency waves as “potentially carcinogenic”. But most of the research to date that has studied the issue, was retrospective, ie participants reported using their mobile phone after cancer diagnosiswhich can lead to misleading estimates.
THE new prospective study (prospective study) by his epidemiologists University of Oxford and the IACRwhich was published in Journal of the National Cancer Instituteincluded 776,156 women before developing a disease and which were monitored in depth for up to 14 years, to investigate a possible link between cell phone use and appearance of tumors in the brainsuch as glioma (tumor of the nervous system), auditory neuroma (tumor of the nerve that connects the brain to the inner ear), meningioma (tumor of the membrane that surrounds the brain) and pituitary tumor.
During the study 3,268 women (0.42% of the total) showed a brain tumor. But there was no statistically significant difference between those who had never used a cell phone and those who did, which was true for all types of brain cancer.
There was also no increase in the risk of brain cancer in those who used their mobile phones daily and / or for over ten years. Finally, the chance of a tumor appearing was the same on the left and right side of the head, although most cell phone users use it by holding it on the right side.
THE researcher Dr. Kristin Peary of the Cancer Epidemiology Unit of the Oxford Department of Public Health “These results support the growing evidence that cell phone use under normal circumstances does not increase the risk of brain tumors,” he said.
Although the findings are reassuring, according to the researchers, remains unclear whether the risks of using a mobile phone are different for those who use their device very often. In this British study only 18% of people were talking on their cell phones about more than 30 minutes per week. The researchers said that one can reduce one’s exposure to cell phone waves by using “hands-free” or speakers.
THE IARC researcher Joachim Sitz “Mobile technologies are constantly improving, so the latest generations of devices emit significantly less power. However, given the lack of data for very frequent users, a good precautionary approach is to advise on reducing unnecessary exposure to mobile.” “.
