Abstract

Category: Epidemiology Tags: RF-EMF, cancer risk, police officers, TETRA, epidemiology, mobile radio, occupational health DOI: 10.1002/ijc.70255 URL: onlinelibrary.wiley.com Overview Exposure to radiofrequency electromagnetic fields (RF-EMF) from mobile phones and other wireless devices has been classified as possibly carcinogenic to humans. This study used data from 48,457 police officers and staff enrolled in the Airwave Health Monitoring Study to investigate associations between personal radio use and cancer risk. Study Design & Methods - Used Cox proportional hazard regressions to analyze cancer risk. - Personal radio use and duration were estimated by combining objective call duration data from the Home Office and self-reported data with gradient boosting methods. - Median follow-up: 11 years. Findings - There were 1,502 incident cancer cases, including 146 cancers of the head, neck, and central nervous system (CNS). - No association was found between personal radio use and risk of all cancers (HR = 0.96, 95% CI: 0.79, 1.15) or head/neck/CNS cancers (HR = 0.74, 95% CI: 0.39, 1.38). - Doubling minutes of call duration was not associated with increased hazard for cancers studied. - Results were similar when considering exposure to RF-EMF via mobile phone use and when restricting analyses to police officers only. Additional Observations - No evidence was found for a non-linear association between call duration and cancer risk. - Those with higher call duration (90th percentile) had a non-statistically significant 9% higher risk for all cancers, and 40% higher risk for head/neck/CNS cancers. - No discernible associations between mobile phone use and cancer risk were detected. Conclusion No evidence was found of an association between TETRA use and increased cancer risk among police officers, though the data do not exclude a modestly greater risk with high usage. Wide confidence intervals indicate both increased and decreased risks are possible, and a definite conclusion cannot be reached at this time. Longer follow-up could provide clearer answers. The possible carcinogenicity of RF-EMF remains a concern and warrants ongoing monitoring in occupational settings.

Main findings

In 48,457 participants followed for a median of 11 years (1502 incident cancers; 146 head/neck/CNS cancers), personal radio use was not associated with all cancers (HR=0.96, 95% CI 0.79–1.15) or head/neck/CNS cancers (HR=0.74, 95% CI 0.39–1.38). Doubling minutes of personal radio call duration was not associated with all cancers (HR=1.00, 95% CI 0.96–1.04) or head/neck/CNS cancers (HR=1.09, 95% CI 0.97–1.22); results were reported as similar for mobile phone RF-EMF exposure and in analyses restricted to police officers.

Outcomes measured

Incident cancer (all cancers)
Incident cancers of the head, neck and central nervous system (CNS)

Limitations

Exposure metrics were derived by combining objective call-duration data with self-reported data using gradient boosting methods (potential exposure misclassification).
Frequency band and RF-EMF dose metrics (e.g., SAR) were not reported in the abstract.
Relatively small number of head/neck/CNS cancer cases (n=146) may limit precision.
