Abstract

Overview

The letter by Mortazavi et al. critiques an earlier editorial which discussed the relationship between cell phone use and brain tumors, emphasizing the limitations in current cohort studies and highlighting the need for caution due to the proven formation of free radicals after RF-EMF exposure.

Findings

• Confirmation of free radical formation after RF-EMF exposure, suggesting potential health risks despite limited cohort data.
• Discussion of meta-analysis results indicating a possible increased risk of low-grade gliomas associated with long-term mobile phone use.

Conclusion

The authors argue for a more cautious interpretation of studies denying RF-EMF dangers, proposing that all available evidence, including the nonlinear J-shaped dose-response relationship similar to that seen with ionizing radiation, supports potential cancer risks from radiofrequency electromagnetic fields.
