studies that contradict each other


  • A follow-up of 800,000 women in the UK over 10 years shows no increase in brain tumor risk associated with mobile phone use
  • A follow-up of 800,000 women in the UK over 10 years shows no increase in brain tumor risk associated with mobile phone use
  • Previous studies had shown that the risk of brain tumors associated with mobile phones was present for 17 minutes of daily use for 10 years
  • International Agency for Research Against Cancer sees link between mobile phones and brain tumors as possible

This is a study that will undoubtedly make people talk. Because it addresses a controversial topic, that of the potential danger of mobile phone waves, and above all because it presents findings that are not consistent with other works on the same topic. According to the Journal of National Cancer Institute (JNCI), which publishes research conducted by Oxford academics, the use of mobile phones cannot cause brain tumours.

20 minutes of use per week

According to this study, which involved nearly 800,000 women born between 1935 and 1950 and questioned about their health data and their habits in the context of mobile phone use, for the first time in 2001 and for the second time in 2011, the risk of brain tumours. The risk of development would be “statistically insignificant” compared to those who never used a mobile phone. This is for users speaking over a period of 10 years and at least 20 minutes per week.

This is what, if not contradictory, in any case underscores the impact of the situation on the subject of the International Agency for Research on Cancer (a structure that WHO relies on). While British researchers in 2011 observed a 39% increase in brain tumors over the past twenty years, the IARC confirmed that the increasingly common use of mobile phones could be one of the possible causes and called electromagnetic radiation “probably carcinogenic”. classified as. ,

Other less convincing studies

“The use of these phones in moderate conditions does not appear to increase the risk of brain tumors,” JNCI study co-author Kirsten Perty responded today. A certainty that will not necessarily be shared. Nor by associations currently concerned about the potential health consequences of deploying 5G networks. And even less by other scientists, such as academics from Berkeley in California, who uncovered in July 2021 that people who use their telephones for 17 minutes a day have a 60% increased risk of developing tumors. Of course, this duration of use is much longer than that adopted by the Oxford researchers’ study, but this increase in risk appears to be considerable!

To reach this more worrying result, the Berkeley scientists explained that interference between mobile phone signals and cellular mechanisms produced a “stress protein” that is capable of damaging DNA, according to more than 40 studies conducted in various Countries such as the United States, United Kingdom, Sweden, Japan or New Zealand based on the analysis.
