Such results were obtained by scientists from Oxford University (UK) and the International Agency for Research on Cancer (IARC), whose article was published in the Journal of the National Cancer Institute.
Since, when talking on a mobile phone, a person holds it near the head, the radio waves emitted by the device penetrate a few centimeters into the brain, and the highest impact in this case are the temporal and parietal lobes of the brain. This raises concerns that mobile phone users may be at increased risk for brain cancer. In recent years, there has been a surge in concerns about the proliferation of 5G networks. However, studies show conflicting results in this regard.
To clarify this question, the authors of the new study analyzed data on more than 776,000 women born in Britain between 1935 and 1950. In 2001, these women were interviewed about the use of mobile phones. The survey was then repeated in 2011. Over 14 years of follow-up, more than 3,200 cases of brain cancer have been reported among the participants.
Analysis of the collected information showed that those who regularly used a mobile phone, and those who have never used this device, have about the same level of risk of developing a malignant brain tumor.
And this also applies to cancer affecting the temporal and parietal lobes.
No significant difference was found in the risk of developing various specific types of brain cancer: gliomas, meningiomas, auditory nerve neuromas, pituitary cancer and eye cancer. However, those who spoke on the phone every day, those who used it for 20 minutes a week, and those who used the device regularly for more than ten years were less likely to develop any of these cancers.
In addition, mobile phone users have had the same incidence of tumors in the right and left hemispheres of the brain, despite the fact that people tend to hold the phone more often in the right ear than in the left.
All this allowed researchers to conclude that the use of mobile phones in normal conditions does not increase the risk of brain cancer. At the same time, scientists say, it remains unclear whether this conclusion is true for those people who use the phone much more than the typical participants in the study. Among them, only 18% spoke on the phone for more than half an hour a week.
Be that as it may, the authors of the study recommend that those who are accustomed to talking a lot on the phone, use a speakerphone more often to reduce the level of radiation exposure to the brain.
