A multicenter case-control study in Iran reported that self-reported prolonged mobile phone use was associated with higher odds of confirmed and suspected breast cancer status. The authors emphasize that the findings do not imply causation and note limitations including self-reported exposure and potential residual confounding. They call for larger prospective studies with objective exposure assessment.
The International Collaborative Animal Study of Mobile Phone Radiofrequency Radiation Carcinogenicity and Genotoxicity: The Japanese Study
This PubMed-listed animal study reports results from the Japanese arm of an international Japan–Korea collaboration evaluating whether long-term mobile-phone-like RF-EMF exposure causes cancer or genetic damage in rats. Male Sprague Dawley rats were exposed to 900 MHz CDMA-modulated RF-EMF at a whole-body SAR of 4 W/kg for nearly 18.5 hours/day over two years, alongside OECD/GLP genotoxicity and carcinogenicity testing. The authors report no statistically significant increases in neoplastic or non-neoplastic lesions in major organs and no evidence of DNA or chromosomal damage, concluding the findings do not support reproducible carcinogenic or genotoxic effects under these conditions.

Sensitivity analyses (including MR-Egger and heterogeneity/asymmetry tests) were reported as suggesting the LAAS finding was robust.
Bacterial Adaptation to Radiofrequency Electromagnetic Fields Based on Experiences from Ionizing Radiation
This 2025 review summarizes historical and modern literature on how bacteria may adapt to radiofrequency electromagnetic fields from common sources such as mobile phones and Wi-Fi. It argues that RF-EMF exposure can influence bacterial survival mechanisms and could potentially compromise therapeutic interventions by promoting increased resistance. The authors frame these possibilities as a public health concern and call for continued research and precaution.
Associations between Individual and Geospatial Characteristics and Power of 4G Signals Received by Mobile Phones
This exposure assessment study analyzed smartphone-logged 4G LTE RSSI and GPS data from adults in France to identify determinants of downlink signal strength. RSSI varied with geospatial factors (distance to antennas, antenna density, urbanicity) and time of day, and was also influenced by technical smartphone parameters. The study reports an estimated electric field strength derived from RSSI, but notes high uncertainty in this conversion.
Numerical Analysis of Human Head Exposure to Electromagnetic Radiation Due to 5G Mobile Phones
This conference paper uses numerical simulations to evaluate near-field exposure and thermal effects in a detailed human head model from a realistic 5G mobile phone operating at 26 GHz. The preliminary modeling suggests moderate, localized temperature increases in superficial tissues. The authors emphasize the need for higher-resolution models, refined tissue segmentation, longer exposure durations, and varied phone placements to better characterize potential impacts.
Assessment of Electromagnetic Exposure to a Child and a Pregnant Woman Inside an Elevator in Mobile Frequencies
This study uses anatomically detailed computational models of a five-year-old girl, a pregnant woman in the third trimester, and a fetus to simulate mobile phone RF exposure inside an elevator cabin. Simulations at 1000 MHz and 1800 MHz across 48 configurations evaluated SAR10g, whole-body SAR, and maximum temperature. The abstract reports that configuration (positioning and phone orientation) can substantially change absorption and temperature metrics and calls for broader scenario testing to inform safety guidance for vulnerable populations.
Greater prevalence of symptoms associated with higher exposures to mobile phone base stations in a hilly, densely populated city in Mizoram, India
This cross-sectional study compared 183 higher-exposed residents with 126 matched reference residents and assessed symptoms via questionnaire alongside in-home RF-EMF power density measurements from mobile phone base stations. Higher exposure (including proximity within 50 m and power densities of 5–8 mW/m2) was reported to be associated with increased symptom prevalence across mood-energy, cognitive-sensory, inflammatory, and anatomical categories. The authors conclude that current public exposure limits may be inadequate for long-term, non-thermal biological impacts and call for precautionary policy updates.
Trends in Malignant and Benign Brain Tumor Incidence and Mobile Phone Use in the U.S. (2000-2021): A SEER-Based Study
This SEER-based ecological study examined U.S. trends (2000–2021) in malignant and benign brain tumor incidence and compared them with national mobile phone subscription trends. Malignant brain tumor incidence in adolescents and adults declined slightly, while benign brain tumor incidence increased over time; temporal lobe tumors and benign acoustic neuromas showed little change. The authors interpret these patterns as not supporting an association between mobile phone use and increased brain cancer risk, while recommending continued surveillance given rising benign tumor incidence and potential latency.
Does Electromagnetic Pollution in the ART Laboratory Affect Sperm Quality? A Cross-Sectional Observational Study.
This cross-sectional observational study assessed sperm motility after one hour of in vitro exposure of semen samples to EMFs from different laboratory sources in an IVF setting. It reports a statistically significant reduction in progressive sperm motility after exposure to mobile phones and Wi-Fi repeaters, while other EMF-emitting equipment showed no significant effect. The authors interpret the findings as indicating a potential negative impact of specific RF sources and call for further research, alongside practical mitigation suggestions in IVF laboratories.
Electromagnetic fields from mobile phones: A risk for maintaining energy homeostasis?
This narrative review discusses low-intensity RF-EMF exposure, primarily from mobile phones, with a focus on thermoregulation and energy homeostasis. It reports that many rodent studies at 900 MHz describe cold-like thermoregulatory and behavioral responses and molecular findings suggestive of WAT browning, while BAT transcriptional changes typical of cold exposure were not observed. The authors indicate short-term adaptations may not disrupt homeostasis, but emphasize uncertainty about long-term consequences and call for further research, including at 5G-relevant frequencies.
Impact of mobile phone-emitted non-ionizing electromagnetic radiation on parotid gland function: A comprehensive study
This cross-sectional study of 104 university student volunteers assessed whether mobile phone-emitted non-ionizing electromagnetic radiation is associated with changes in parotid gland-related salivary measures. The authors report higher salivary flow rate and pH with longer mobile phone usage duration, along with side-related differences in albumin, IMA, and IMAR. The paper concludes that consistent exposure to mobile phone NIER and associated heat adversely affects parotid gland function and frames this as a health risk, while calling for further long-term research.
Exploring the impact of environmental factors on male reproductive health through epigenetics
This narrative review discusses how environmental factors may affect male reproductive health through epigenetic mechanisms, including DNA methylation, histone modifications, chromatin remodeling, and non-coding RNA regulation. It reports that electromagnetic radiation, particularly from mobile phones and wireless devices, is linked in the reviewed literature to reduced sperm count and motility, increased oxidative stress, and chromatin damage. The authors conclude there is a substantive connection between EMF exposure and adverse male reproductive outcomes and suggest practical risk-reduction guidance.
Potential Impacts of Radiofrequency Electromagnetic Fields on the Central Nervous System, Brain Neurotransmitter Dynamics and Reproductive System
This review discusses potential impacts of radiofrequency electromagnetic fields from technologies such as Wi‑Fi and mobile phones on the central nervous system, neurotransmitter dynamics, and reproductive health. It describes proposed mechanisms including oxidative stress, thermal effects, altered neurotransmitter activity, ion channel changes, and neuronal apoptosis, while acknowledging conflicting evidence. The authors note that Wi‑Fi RF exposure has not been confirmed to exceed safety guidelines but argue that updated standards and long-term studies are needed, particularly for children/adolescents and in the context of expanding technologies such as 5G.
Impairment of Oogenesis and Folliculogenesis in Neonatal Rats after Maternal Exposure to Mobile Phones
This animal study examined maternal mobile phone exposure during different gestational windows in Wistar rats and assessed ovarian development and hormones in neonatal offspring. Compared with sham (phone off), exposed groups (standby and conversation/standby) were reported to have lower neonatal estrogen and progesterone and reduced primordial follicle/primary oocyte measures, with stronger effects after longer exposure. The study also reports increased primordial follicle apoptosis, particularly in the conversation/standby condition, and notes effects even with first-week gestational exposure.
Effects of Mobile Electromagnetic Exposure on Brain Oscillations and Cortical Excitability: Scoping Review
This scoping review evaluates evidence on mobile phone electromagnetic exposure and its effects on brain oscillations and cortical excitability in healthy individuals. Across 78 EEG studies (and 2 TMS studies), the authors report that exposure may be linked to changes in neural activity, including increased amplitudes in several EEG bands and possible changes in cortical silent period. However, substantial methodological inconsistency across studies limits firm conclusions, and the review highlights limited evidence for 5G/mmWave exposures and argues for precaution and potential guideline revision.
