Regular use of mobile phones does not cause brain cancer. This is confirmed by a study carried out on 770,000 women and published in the “Journal of the National Cancer Institute”.
As a result of these data, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO), which had previously declared the use of mobile phones as ‘possibly carcinogenic’, now concludes that, for the user means of mobile phones, these devices are safe.
And what about mobile addicts? The report also concludes that there is no evidence that people who talk on the phone for about 7 to 10 hours a week or more are at increased risk.
Although, they acknowledge, the possibility cannot be ruled out.
For a person in normal use, says lead researcher Joachim Schuezfrom the IARC, “we have strong and convincing evidence that mobile phone use does not cause problems, while for the smaller group of people with very heavy use, we would give some advice.”
The important study builds on earlier research. «The longer you watch people, the more robust the data becomes. Each new study is a piece of the puzzle», he says.
Schüz advises mobile addicts that, while there is no evidence to suggest they are at increased risk, to apply the precautionary principle and use the speakerphone or headphones where possible to minimize contact the device has with their head.
The researchers used data from the Million Women Study – a large, ongoing research project that has recruited one in four UK women born between 1935 and 1950.
About 776,000 participants completed questionnaires about their mobile phone use in 2001, and about half of them were asked again in 2011.
The study followed the participants for an average of 14 years.
“The results support accumulating evidence that normal mobile phone use does not increase the risk of brain tumours,” said Kirstin Pirie of the University of Oxford Department of Population Health.
Since mobile phones are placed close to the head, the radiofrequency waves they emit penetrate several centimeters into the brain, with the temporal and parietal lobes being the most exposed. This has raised concerns that mobile users may be at increased risk of developing brain tumors.
The IARC had classified radio frequency waves as “possibly carcinogenic», and fears were reignited more recently with the launch of 5G technologies.
But this new study debunks these theories.
