studies that contradict each other


  • Follow-up of 800,000 women over 10 in UK shows no increase in brain tumor risk associated with mobile phone use
  • Follow-up of 800,000 women over 10 in UK 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 existed at a daily use of 17 minutes for 10 years
  • The International Agency for Research on Cancer considers the connection between mobile phones and brain tumors possible

This is a study that will no doubt get people talking. Because it deals with a controversial topic, namely the potential danger of cell phone waves, and above all because it presents conclusions that are not in line with other work on the same topic. According to the Journal of the National Cancer Institute (JNCI), which publishes research carried out by Oxford academics, the use of a mobile phone could not cause a brain tumor.

20 minutes of use per week

According to this study, which involved almost 800,000 women born between 1935 and 1950 and asked about their health data and their habits regarding mobile phone use for the first time in 2001 and the second time in 2011, the risk of developing a brain tumor. compared to people who never use a mobile phone would be “statistically insignificant”. This over a period of 10 years and for users who talk at least 20 minutes a week.

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

Other less reassuring studies

“The use of these phones in moderate conditions does not increase the risk of brain tumor”, replies Kirstin Pirtie today, co-author of the JNCI study. A certainty that will not necessarily be shared. Nor by the associations that are currently concerned about the possible health consequences of the spread of the 5G network. And even less by other scientists, such as those academics from Berkeley in California who highlighted in July 2021 that the risk of developing tumors increased by 60% for those who use their phone 17 minutes a day. Admittedly, this duration of use is much longer than that adopted by the Oxford researchers’ study, but this increase in risk appears to be significant!

To reach this much more worrying result, the Berkeley researchers explained that interference between mobile phone signals and cellular mechanisms caused the creation of “stress proteins” capable of causing DNA damage, conclusions based on the analysis of more than 40 studies carried out in different countries such as the USA, Great Britain, Sweden, Japan or New Zealand.
