Comments on analysis of mobile phone use among young patients with brain tumors in Japan

Commentary: Geographic Variations in the Incidence of Glioblastoma and Prognostic Factors Predictive of Overall Survival in US Adults from 2004–2013

“…Over the past decade, my colleagues and I have studied the health effects of cellular phones and their base stations. We have also shown that some of the papers claiming no link between mobile phone use and cancer have methodological errors and/or shortcomings (Mortazavi et al, 2017a , b , 2018 ; Mortazavi, 2018 ). For example, in one of the papers reviewed by our research group, a 400% difference in brain tumors was masked by poor statistical analysis!…”

Comment on ‘Cell phone use and ill health: is there a definite relationship?’

“…3,6,[15][16][17][18][19] Regarding cancer, we have recently addressed the limitations and shortcomings of some of the studies claiming lack of association between exposure to radiofrequency radiation and cancer. 2,[20][21][22] Interestingly, in one of the papers reviewed by our research group, a 400% difference in brain tumours was ignored due to poor statistical analysis. 22 We have shown that current controversy, at least to some extent, can be due to the large variations in the magnitude of exposure to electromagnetic fields in different studies.…”

“…2,[20][21][22] Interestingly, in one of the papers reviewed by our research group, a 400% difference in brain tumours was ignored due to poor statistical analysis. 22 We have shown that current controversy, at least to some extent, can be due to the large variations in the magnitude of exposure to electromagnetic fields in different studies. In this light, we showed that in a similar pattern with ionising radiation, the dose-response relationship for carcinogenesis of non-ionising electromagnetic fields is nonlinear and J-shaped.…”

Response to the comments on “Analysis of Mobile Phone Use Among Young Patients with Brain Tumors in Japan”

“…We are writing in response to comments by Mortazavi [] on our article, “Analysis of Mobile Phone Use Among Young Patients with Brain Tumors in Japan,” which was published in Bioelectromagnetics [Sato et al, ].…”
