“…Second, de Vocht and Röösli claimed that we failed to notice "that both the INTERPHONErelated studies and miscellaneous studies are largely in agreement and do not point to an excess cancer risk from mobile phone use. Evidence of large excess cancer risks are almost exclusively based on the studies by the Hardell group..." [1]. We acknowledge that the current meta-analysis did not perform detailed subgroup meta-analyses by lifetime cellular phone use for each type of tumor.…”

“…We appreciate Frank de Vocht and Martin Röösli's interest [1] in our study and their recognition of the importance of conducting regular, systematic syntheses of the epidemiological evidence regarding the tumor risk from mobile phone (i.e., cellphone) use. They claim we made "peculiar decisions" in our review and meta-analysis of 46 case-control studies [2], and they tried to downplay the tumor risk from cellphone use by arguing that studies conducted by the Hardell group overestimated the risk compared to other studies.…”

Reply to Brzozek et al. Comment on “Choi et al. Cellular Phone Use and Risk of Tumors: Systematic Review and Meta-Analysis. Int. J. Environ. Res. Public Health 2020, 17, 8079”

“…The Brzozek et al letter is the second letter to the editor regarding our current study. Ken Karipidis [ 1 ] and Martin Röösli [ 4 ], the senior authors of these two letters, are two of the 14 commissioners on the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Their interest in our paper is not likely coincidental, because the major finding from both of our review studies was that heavier, long-term cell phone use was associated with significantly increased tumor risk [ 2 , 3 ].…”

“…Since all but one of the concerns in the Brzozek letter were raised in the letter by de Vocht and Röösli [ 4 ], to avoid redundancy, we request that readers see our response to de Vocht and Röösli which addresses these other concerns [ 5 ]. Hence, in our reply below, we simply address Brzozek et al’s unique concern about our paper.…”
