This case-control study in Mexico City (2017–2022) evaluated residential ELF-MF and device-use proxies for RF exposure in relation to childhood CNS tumor risk. Elevated residential ELF-MF (≥0.4 μT) was associated with approximately doubled odds of CNST, while cell phone use showed no association. Prolonged tablet use, with or without internet connectivity, was reported to be associated with higher CNST risk.
Occupational exposure to extremely low-frequency magnetic fields (ELF-MF) and postmenopausal breast cancer risk
This population-based case-control study in Montréal (2008–2011) evaluated occupational extremely low-frequency magnetic field (ELF-MF) exposure and postmenopausal breast cancer risk using a job-exposure matrix linked to lifetime job histories. Overall, it reports no association between occupational ELF-MF exposure and postmenopausal breast cancer. However, analyses focusing on specific exposure windows (0–10 years before interview or during breast development) reported some positive associations, especially for ER+/PR+ tumours.
The effect of alpha-lipoic acid on liver damage induced by extremely low-frequency electromagnetic fields in a rat model
This rat study assessed whether alpha-lipoic acid (ALA) modifies liver effects from extremely low-frequency magnetic field (ELF-MF) exposure. ELF-MF exposure (2 mT, 4 hours/day for 30 days) was associated with increased liver pathology and higher apoptosis markers (TUNEL, caspase-3) compared with other groups. ALA reduced several histopathological changes and lowered TUNEL/caspase-3, but did not improve fibrosis or biliary proliferation.
Residential exposure to magnetic field due to high-voltage power lines and childhood leukemia risk in mainland France - GEOCAP case-control study
This French GEOCAP registry-based case-control study evaluated childhood acute leukemia risk in relation to residential proximity to high-voltage overhead power lines and modeled ELF magnetic-field exposure. It reports an increased risk for children under 5 living within 50 m of power lines, particularly when restricting to high-quality geocoded addresses. However, modeled ELF-MF exposure >0.3 µT was not associated with increased risk, and the authors suggest proximity may capture other factors and call for further research and precaution.
