Expert Report by Former U.S. Government Official Concludes High Probability Radio Frequency Radiation Causes Brain Tumors
Christopher J. Portier, Ph.D., former director of the National Center for Environmental Health at the Centers for Disease Control and Prevention (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR), and a scientific advisor for the World Health Organization (WHO), recently completed an expert report on brain tumor risk from exposure to radio frequency (RF) radiation used in cellphone technology.
After completing a comprehensive review of the scientific literature, Dr. Portier concluded:
“In my opinion, RF exposure probably causes gliomas and neuromas and, given the human, animal and experimental evidence, I assert that, to a reasonable degree of scientific certainty, the probability that RF exposure causes gliomas and neuromas is high.”
In 2011, Dr. Portier was selected to represent the CDC on an expert working group convened by the WHO International Agency for Research on Cancer (IARC) to review the carcinogenicity of RF radiation.
Based upon recommendations of the expert panel, the IARC declared RF radiation “possibly carcinogenic to humans” (Group 2B) and the following year issued a monograph summarizing the evidence. Because the preponderance of the peer-reviewed research published since 2011 supports the need to upgrade this classification, the IARC has prioritized a new review to be conducted by 2024.
Dr. Portier’s 176-page expert report including 443 references was prepared for the plaintiffs in a major product liability lawsuit, Murray et al. v Motorola, Inc. et al., filed in the Superior Court for the District of Columbia against the telecommunications industry. The report appears as Exhibit 3 in a recent filing with the Court.

Dr. Portier’s conclusion is consistent with the results of our recently published meta-analysis of the case-control research on cellular phone use and tumor risk.

We investigated whether cellular phone use was associated with increased risk of tumors using a meta-analysis of case-control studies. PubMed and EMBASE were searched from inception to July 2018. The primary outcome was the risk of tumors by cellular phone use, which was measured by pooling each odds ratio (OR) and its 95% confidence interval (CI). In a meta-analysis of 46 case-control studies, compared with never or rarely having used a cellular phone, regular use was not associated with tumor risk in the random-effects meta-analysis. However, in the subgroup meta-analysis by research group, there was a statistically significant positive association (harmful effect) in the Hardell et al. studies (OR, 1.15—95% CI, 1.00 to 1.33— n = 10), a statistically significant negative association (beneficial effect) in the INTERPHONE-related studies (case-control studies from 13 countries coordinated by the International Agency for Research on Cancer (IARC); (OR, 0.81—95% CI, 0.75 to 0.89—n = 9), and no statistically significant association in other research groups’ studies. Further, cellular phone use with cumulative call time more than 1000 hours statistically significantly increased the risk of tumors. This comprehensive meta-analysis of case-control studies found evidence that linked cellular phone use to increased tumor risk.
