This review argues that EMF exposure is associated in the literature with several adverse central nervous system outcomes, including blood-brain barrier disruption, oxidative stress, neurotransmitter changes, cognitive effects, and neurodevelopmental impacts. It reports that evidence on EMFs and brain tumors is conflicting, while noting WHO’s classification of radiofrequency EMFs as possibly carcinogenic to humans. The authors highlight prenatal and childhood periods as potentially more vulnerable and call for more standardized long-term and mechanistic research to guide public health policy.

This letter critiques the WHO-sponsored systematic review by Karipidis et al. (2024) on RF-EMF exposure and cancer risk. The authors argue the review has serious methodological and interpretative flaws, including issues with study selection and data analysis. They contend that the review’s conclusion of "no clear evidence" may be misleading and should not be used as a basis for health policy or safety guidelines.
