Studies that contradict each other

  • Follow-up of 800,000 women over 10 years in UK shows no increased risk of brain tumors associated with mobile phone use
  • Follow-up of 800,000 women over 10 years in UK shows no increased risk of brain tumors associated with mobile phone use
  • Previous studies have shown that the risk of brain tumors associated with cell phones exists for 17 minutes of daily use for 10 years.
  • The International Agency for Research on Cancer considers the link between cell phones and brain tumors possible

It is a study that will undoubtedly be talked about. Because it addresses a controversial subject, the potential danger of mobile phone waves, and above all because it presents conclusions that contradict other works on the same subject. According to the Journal of the National Cancer Institute (JNCI), which publishes research conducted by Oxford academics, cell phone use cannot cause brain tumors.

20 minutes of use per week

According to this study of nearly 800,000 women born between 1935 and 1950 who questioned themselves for the first time in 2001 then in 2011 about their health data and their habits of using the mobile phone, the risk of developing a brain tumor increased. Compared to people who never use a cell phone, this would be “statistically insignificant”. It’s over 10 years and for users who talk at least 20 minutes a week.

This is what, if not contradictory, in no way lessens the impact of the situation on this subject of the International Agency for Research on Cancer (a structure based on the World Health Organization). While British researchers noted in 2011 a 39% increase in brain tumors over the past 20 years, the International Agency for Research on Cancer confirmed that the increasingly common use of mobile phones could be a possible cause. , classifying electromagnetic radiation fields as “likely to be carcinogenic.”

Other studies are less reassuring

“The use of these phones in mild conditions does not increase the risk of brain tumors”, responds today Kirstin Pirtie, co-author of the JNCI study. Certainty will not necessarily be shared. Nor by associations which are currently concerned about the potential health consequences of the deployment of 5G. And even less so by other academics, eg These academics from Berkeley, CA who were in the spotlight in July 2021 The risk of developing tumors increased by 60% for those who used their phones 17 minutes a day. Admittedly, this duration of use is much longer than that used in the study by the Oxford researchers, but this increased risk appears significant!

To arrive at this most disturbing discovery, the Berkeley scientists explained that the interference between cell phone signals and cellular mechanisms caused the formation of “stress proteins” capable of causing DNA damage, conclusions based based on an analysis of more than 40 studies conducted in various countries such as the United States, United Kingdom, Sweden, Japan and New Zealand.
