Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case-control study with an additional suspected comparison group

Research PubMed: RF-EMF health Feb 2, 2026

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

Research PubMed: RF-EMF health Jan 13, 2026

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.

U.S. policy on wireless technologies and public health protection: regulatory gaps and proposed reforms

Policy PubMed: RF-EMF health Jan 5, 2026

This PubMed-listed paper argues that the U.S. regulatory framework for radiofrequency radiation (RFR) from wireless technologies is outdated, lacks adequate oversight and enforcement, and has not been meaningfully updated since 1996. It contends that FCC exposure limits focus on short-term, high-intensity effects and do not address long-term, low-intensity exposures, with insufficient safeguards for children, pregnancy, and other vulnerable groups. The authors also discuss alleged regulatory capture, gaps in monitoring and compliance, and propose reforms including independent research, updated safety limits, and stronger pre- and post-market surveillance.

This international collaborative animal study (Japanese arm) evaluated carcinogenicity and genotoxicity in male Sprague Dawley rats exposed long-term to 900 MHz CDMA-modulated RF-EMFs at 4 W/kg whole-body SAR. The abstract reports no statistically significant increases in neoplastic or non-neoplastic lesions in major organs and no evidence of genotoxicity on comet or micronucleus testing. The authors conclude the findings provide strong evidence of no reproducible carcinogenic or genotoxic effects under the studied conditions.

The effects of acute and chronic exposure of 3G UMTS 2100 MHz radiofrequency radiation on rat mismatch negativity

Research RF Safe Research Library Jan 1, 2026

This rat study examined acute (1-week) and chronic (10-week) exposure to 2100 MHz radiofrequency radiation (3G UMTS-like) and assessed auditory mismatch negativity (MMN) alongside biochemical and histological brain measures. The abstract reports that acute exposure was associated with reduced MMN-related electrophysiological parameters and changes in GluR2 and GFAP with observed brain ultrastructural alterations. Chronic exposure showed opposite protein trends and enhanced MMN parameters versus chronic controls, and lipid peroxidation was not significantly different.

Mitigating Heat-Induced Sperm Damage and Testicular Tissue Abnormalities: The Protective Role of Radiofrequency Radiation from Wi-Fi Routers in Rodent Models

Research PubMed: RF-EMF health Dec 11, 2025

A rodent experimental study on PubMed reports that 2.45 GHz Wi‑Fi radiofrequency exposure may reduce heat stress–related damage in male rat testes and sperm parameters. The authors describe this as the first study examining a potentially protective effect of RF‑EMF against heat-induced testicular abnormalities, suggesting an adaptive response mechanism. They emphasize that further research is needed to clarify mechanisms and implications.

Policy & governance: why the failure is structural (S4 MITO spin + “Clean Ether Act”)

Policy RF Safe Nov 25, 2025

This RF Safe article argues that the main barrier to addressing radiofrequency radiation (RFR) and other non-native EMFs is structural policy and governance failure rather than a lack of scientific evidence. It cites the 2021 D.C. Circuit decision in Environmental Health Trust et al. v. FCC as criticism of the FCC’s rationale for keeping 1996 RF exposure limits, and it points to the Radiation Control for Health and Safety Act of 1968 as a mandate for HHS to run a research-backed radiation control program. The piece also references the U.S. National Toxicology Program’s animal findings and frames the lack of further NTP RF studies as a policy shortcoming, while promoting an “S4 MITO spin” mechanistic framework and a proposed “Clean Ether Act.”

S4 MITO spin framework – talking points

Independent Voices RF Safe Nov 25, 2025

RF Safe presents “S4 MITO spin” as a proposed mechanistic framework arguing that peer-reviewed evidence can be unified to explain reported biological effects from radiofrequency radiation (RFR) and other non-native EMFs. The post highlights animal studies (notably NTP and Ramazzini) as showing carcinogenic “signals” and emphasizes non-linear dose–response patterns, asserting relevance to regulatory exposure limits. It frames the model as empirically grounded and testable, while acknowledging it is not a complete theory of all EMF effects.

White Paper: Non-Thermal Radiofrequency Radiation from Wireless Technology: Established Biological Harm, Regulatory Capture, and a Path Forward with Biologically Compatible Alternatives

Independent Voices RF Safe Nov 21, 2025

RF Safe published a white paper by John Coates arguing that current wireless (RF) exposure limits focus on thermal heating while ignoring “non-thermal” biological effects reported in many studies. The piece cites animal studies (U.S. National Toxicology Program and Ramazzini Institute) and links RF exposure to outcomes such as rare tumors and declining sperm counts, and it alleges regulatory capture. It promotes Li‑Fi and other “biologically compatible” connectivity as a proposed path forward.

The Single Mechanism That Explains Everything

Independent Voices RF Safe Nov 21, 2025

RF Safe argues that a single biological mechanism explains a wide range of alleged harms from real-world radiofrequency radiation, emphasizing pulsed/modulated signals. The post claims these pulses affect voltage-gated ion channels (via the S4 voltage sensor), disrupting calcium signaling and leading to health effects. It also alleges industry “cover-up” and criticizes RF exposure limits as unchanged since 1996, while referencing animal findings and a personal anecdote.

RFR can drive autoimmunity through the S4 voltage sensor 

Independent Voices RF Safe Nov 4, 2025

RF Safe argues that radiofrequency radiation (especially pulsed or modulated signals with low-frequency components) can alter local membrane potentials at nanometer scales where voltage-gated ion channel S4 sensors operate. It claims these shifts could change ion channel gating in immune cells, altering calcium and proton signaling, increasing oxidative stress, and promoting innate immune activation that may contribute to autoimmune-like inflammation. The piece presents a mechanistic causal chain and highlights heart and nerve tissue as potentially more susceptible due to high ion-channel density and mitochondrial content, but does not present new study data in the provided text.

U.S. policy on wireless technologies and public health protection: regulatory gaps and proposed reforms

Research RF Safe Research Library Jan 1, 2025

This policy-focused paper contends that U.S. oversight of radiofrequency radiation from wireless technologies is outdated and insufficient, with exposure limits and testing approaches not aligned with modern long-term, chronic exposure scenarios. It emphasizes gaps in protections for children, pregnancy, vulnerable populations, workers, and wildlife, and describes limited monitoring, research, and enforcement capacity. The author proposes reforms to improve independent research, science-based limits, surveillance, and regulatory transparency.

Research RF Safe Research Library Jan 1, 2025

This animal study examined whether paternal exposure to 4.9 GHz (5G) radiofrequency radiation affects male offspring in C57BL/6 mice. It reports increased anxiety-like behavior and reduced sperm quality in adult F1 males from exposed fathers, alongside reported LRGUK hypermethylation and reduced LRGUK expression in testes. The abstract reports no significant effects on depression-like behavior, learning/memory, or fertility across F1–F2 generations.

Development and Testing of a Novel Whole-body Exposure System for Investigative Studies of Radiofrequency Radiation in Rodents (NIEHS)

Research RF Safe Research Library Jan 1, 2025

This NIEHS report describes the development and testing of a flexible whole-body radiofrequency radiation exposure system for rats and mice using updated signals relevant to wireless technologies. In 5-day studies with CDMA- and GSM-modulated signals, no visible behavioral responses were observed and comet assays reported no DNA damage in multiple tissues. The report notes technical challenges, particularly difficulty obtaining reliable body temperature measurements during exposure, and positions the system as a prototype for future mechanistic toxicology studies.

Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case-control study with an additional suspected comparison group

Research RF Safe Research Library Jan 1, 2025

This multicenter case-control study in Iran (n=226) examined associations between mobile phone use and breast cancer outcomes in women. Reporting more than 60 minutes/day of phone conversations was associated with higher odds of confirmed invasive breast cancer and of being classified as a suspected case versus <10 minutes/day. The authors emphasize that the results do not establish causation and may be influenced by self-reported exposure and residual confounding, warranting cautious interpretation.

Radiofrequency radiation-induced gene expression

Research RF Safe Research Library Jan 1, 2025

This review summarizes studies reporting radiofrequency radiation (RFR)-associated changes in gene expression across biological systems. Reported affected genes relate to cellular stress responses, oxidative processes, apoptosis, DNA damage detection/repair, protein repair, and neural function regulation. The authors highlight reported gene expression effects at or below 0.4 W/kg SAR and argue this challenges current guideline assumptions, while noting that not all studies find significant effects.

Male Reproductive and Cellular Damage After Prenatal 3.5 GHz Radiation Exposure: One-Year Postnatal Effects

Research RF Safe Research Library Jan 1, 2025

This animal study examined whether prenatal exposure to 3.5 GHz radiofrequency radiation (2 hours/day) affects male reproductive outcomes later in life. Male rat offspring assessed at 12 months showed multiple adverse testicular and cellular findings in exposed groups versus sham controls, including impaired spermatogenesis markers, increased abnormal sperm morphology, increased DNA damage, and increased apoptosis, with full-gestation exposure generally most pronounced. The authors interpret the results as evidence of persistent reproductive toxicity from prenatal exposure and call for further mechanistic work and precautionary actions.

The WHO-commissioned systematic reviews on health effects of radiofrequency radiation provide no assurance of safety

Research RF Safe Research Library Jan 1, 2025

This paper evaluates and critiques 12 WHO-commissioned systematic reviews and meta-analyses on RF-EMF health effects across outcomes including cancer and reproductive endpoints. It argues that serious methodological flaws and limitations in the WHO reviews prevent them from providing assurance of safety for cell phones and other wireless devices. The authors highlight reported evidence in the animal cancer review (high certainty for heart schwannomas; moderate certainty for brain gliomas) and describe dose-related adverse effects on male fertility and reproductive outcomes, including at exposure levels below current ICNIRP thresholds.

High Radiofrequency Radiation in the Surroundings of 10 Schools in Örebro, Sweden

Research RF Safe Research Library Jan 1, 2025

This exposure assessment measured outdoor RF radiation from 4G/5G base stations near 10 schools in Örebro, Sweden (October 2024). The authors report maximum levels of 10,716–68,452 μW/m² and state these are far above EUROPAEM EMF guideline ranges; two locations also showed higher peak readings with a second meter. The paper frames these findings as indicating a significant health risk, particularly for children and sensitive groups, though no health outcomes were measured in this study.

Effects of 700MHz radiofrequency radiation (5G lower band) on the reproductive parameters of female Wistar rats

Research RF Safe Research Library Jan 1, 2025

This animal study examined short- and long-term 700 MHz (lower-band 5G) radiofrequency exposure in female Wistar rats, comparing control, sham, and exposed groups. It reports no DNA damage and no change in estrous cycle length, but increased ovarian oxidative stress markers in exposed animals. Long-term exposure was associated with ovarian histopathological alterations, while estradiol and progesterone stayed within normal ranges and testosterone increased slightly but significantly.

The effects of radiofrequency radiation on male reproductive health and potential mechanisms (Review)

Research RF Safe Research Library Jan 1, 2025

This narrative review summarizes human and animal research on radiofrequency (RF) radiation exposure (e.g., mobile phones, Wi‑Fi, occupational sources) and male reproductive outcomes. It reports that the literature links RF exposure with reduced sperm quality and increased DNA damage, often alongside oxidative stress and other proposed biological changes. Although inconsistencies are acknowledged, the authors conclude the overall evidence suggests harmful associations and call for standardized, long-term studies and reconsideration of guidelines.

Mitigating Heat-Induced Sperm Damage and Testicular Tissue Abnormalities: The Protective Role of Radiofrequency Radiation from Wi-Fi Routers in Rodent Models

Research RF Safe Research Library Jan 1, 2024

This rodent study examined whether 2.45 GHz Wi‑Fi router RF-EMF exposure could mitigate heat-stress-related reproductive damage in male rats. The combined RF-EMF + heat group reportedly had improved testicular structure measures and sperm quality versus heat-only, while RF-EMF alone was also reported to alter testis and sperm parameters. The authors interpret the findings as potentially consistent with an adaptive response and call for more research on mechanisms and safety.
