Top Experimental and Epidemiological Studies on Wireless Radiation
Last updated April 27, 2017
Prologue: Epidemiology only proves the past; Experimental/Toxicology Studies indicate future risks/harms
From time to time people ask, “what are the studies I should share with people who state that there is “no evidence?” On this page we have a small sampling of studies that are the evidence.
Cancer and Cancer Promotion:
Yang, M., et al. “Mobile phone use and glioma risk: A systematic review and meta-analysis.” PLoS One, vol. 12, no. 5, 2017.
Meta-analysis found significant positive association between long-term mobile phone use (minimum, 10 years) and glioma. And there was a significant positive association between long-term ipsilateral mobile phone use and the risk of glioma. Long-term mobile phone use was associated with 2.22 times greater odds of low-grade glioma occurrence.
Carlberg, Michael and Lennart Hardell. “Evaluation of Mobile Phone and Cordless Phone Use and Glioma Risk Using the Bradford Hill Viewpoints from 1965 on Association or Causation.” BioMed Research International, vol. 2017, 2017.
When considered vis a vis deductive public health principles, the combined evidence from epidemiology and laboratory studies indicate that meningioma and glioma in the temporal lobe can be considered to be caused by cumulative RF radiation exposure. Experimental findings that RF increases production of reactive oxygen species suggest a potential mechanism.
Prasad, M., et al. “Mobile phone use and risk of brain tumours: a systematic review of association between study quality, source of funding, and research outcomes.” Neurological Sciences, 2017.
Studies with higher quality are more likely to find higher risk of brain tumour, while lower quality studies tend to indicate lower risk/protection
Grell, Kathrine, et al. “The Intracranial Distribution of Gliomas in Relation to Exposure From Mobile Phones: Analyses From the INTERPHONE Study.” American Journal of Epidemiology, vol. 184, no. 11 2016, pp. 818-28.
Similar to earlier results, we found a statistically significant association between the intracranial distribution of gliomas and the self-reported location of the phone. When we accounted for the preferred side of the head not being exclusively used for all mobile phone calls, the results were similar.
Hardell, Lennart and Michael Carlberg. “Mobile phone and cordless phone use and the risk for glioma–Analysis of pooled case-control studies in Sweden, 1997–2003 and 2007–2009.” Pathophysiology, vol. 22, no. 1, 2015, pp. 1-13.
Mobile phone and cordless phone use increased the risk of glioma, with highest risk in the >15–20 years latency group Highest ORs overall were found for ipsilateral mobile or cordless phone use, while the highest risk was found for glioma in the temporal lobe. First use of mobile or cordless phone before the age of 20 gave higher OR for glioma than in later age groups.
Carlberg, Michael and Lennart Hardell. “Decreased survival of glioma patients with astrocytoma grade IV (glioblastoma multiforme) associated with long-term use of mobile and cordless phones.” International Journal of Environmental Research and Public Health, vol. 11, no. 10, 2014, pp. 10790-805.
Elevated HR (decreased survival) for the most malignant glioma type, astrocytoma grade IV, was found for long-term use of mobile and cordless phones. Highest HR was found for cases with first use before the age of 20 years.
Coureau, Gaëlle, et al. “Mobile phone use and brain tumours in the CERENAT case-control study.” Occupational and Environmental Medicine, vol. 71, no. 7, 2014, pp. 514-22.
No association with brain tumours was observed when comparing regular mobile phone users with non-users, however, the positive association was statistically significant in the heaviest users when considering life-long cumulative duration and number of calls for gliomas. Risks were higher for gliomas, temporal tumours, occupational and urban mobile phone use.
Absorbed Exposures to Anatomical Regions of the Brain and Increased Brain Cancer Incidence Rates
Zada, Gabriel, et al. “Incidence trends in the anatomic location of primary malignant brain tumors in the United States: 1992–2006.” World Neurosurgery, vol. 77, no. 3, 2012, pp. 518-24.
Data from 3 major cancer registries demonstrate increased incidences of glioblastoma multiforme in the frontal lobe, temporal lobe, and cerebellum, despite decreased incidences in other brain regions. Although this may represent an effect of diagnostic bias, the incidence of both large and small tumors increased in these regions.
Cardis, Elisabeth, et al. “Risk of brain tumours in relation to estimated RF dose from mobile phones: results from five Interphone countries.” Occupational and Environmental Medicine, vol. 68, no. 9, 2011, pp. 631-40.
Authors found suggestions of an increased risk of glioma in long-term mobile phone users with high RF exposure and of similar, but apparently much smaller, increases in meningioma risk.
Schwann Cell Cancers
Moon et al. “Association between vestibular schwannomas and mobile phone use.” Tumour Biology, vol. 35, no. 1, 2014, pp. 581-7 .
Acoustic neuromas (vestibular schwannomas) occur more frequently on used ear of mobile phones and tumor volume showed a strong correlation with amount of mobile phone use.
Benson, V.S., et al. “Mobile phone use and risk of brain neoplasms and other cancers: prospective study.” International Journal of Epidemiology, vol. 42, no. 3, 2013, pp. 792-802.
Acoustic neuromas were 2 1/2 times more likely in long term users compared to never users (10+ years: RR = 2.46, 95% CI = 1.07-5.64, P = 0.03), with the risk increasing with duration of use (trend among users, P = 0.03).
Hardell, et al. “Pooled analysis of case-control studies on acoustic neuroma diagnosed 1997-2003 and 2007-2009 and use of mobile and cordless phones.” International Journal of Oncology, vol. 43, no. 4, 2013, pp. 1036-44.
This study confirmed previous results demonstrating an association between mobile and cordless phone use and acoustic neuroma.
Hardell, L., M. Carlberg and Mild K. Hansson. “Use of mobile phones and cordless phones is associated with increased risk for glioma and acoustic neuroma.” Pathophysiology, vol. 20, no. 2, 2012, pp. 85-110.
Regarding acoustic neuroma, ipsilateral mobile phone use in the latency group ≥10 years gave OR=1.81, 95% CI=0.73-4.45. For ipsilateral cumulative use ≥1640 h OR=2.55, 95% CI=1.50-4.40 was obtained. Also use of cordless phones increased the risk for glioma and acoustic neuroma in the Hardell group studies.
Interphone Study Group. “Acoustic neuroma risk in relation to mobile telephone use: results of the INTERPHONE international case-control study.” Cancer Epidemiology, vol. 35, no. 5, 2011, pp. 453-64.
In general, ORs were not greater in subjects who reported usual phone use on the same side of the head as their tumour than in those who reported it on the opposite side, but it was greater in those in the 10th decile of cumulative hours of use.
Hardell et al. “Mobile phones, cordless phones and the risk for brain tumours.” International Journal of Oncology, vol. 35, no. 1, 2009, pp. 5-17.
For acoustic neuroma, the highest OR was found for ipsilateral use and >10 year latency, for mobile phone OR=3.0, 95% CI=1.4-6.2 and cordless phone OR=2.3, 95% CI=0.6-8.8.
Schoemaker et al. “Mobile phone use and risk of acoustic neuroma: results of the Interphone case-control study in five North European countries.” British Journal of Cancer, vol. 93, no. 7, 2005, pp. 842-8.
Risk of a tumour on the same side of the head as reported phone use was raised for use for 10 years or longer (OR = 1.8, 95% CI: 1.1-3.1). The study suggests that there is no substantial risk of acoustic neuroma in the first decade after starting mobile phone use. However, an increase in risk after longer term use or after a longer lag period could not be ruled out.
Lonn et al. “Mobile phone use and the risk of acoustic neuroma.” Epidemiology, vol.15, no. 6, 2004, pp. 653-9
The overall odds ratio for acoustic neuroma associated with regular mobile phone use was 1.0 (95% confidence interval = 0.6-1.5). Ten years after the start of mobile phone use the estimates relative risk increased to 1.9 (0.9-4.1); when restricting to tumors on the same side of the head as the phone was normally used, the relative risk was 3.9 (1.6-9.5).
Lim et al. “Trends in Thyroid Cancer Incidence and Mortality in the United States, 1974-2013.” JAMA, vol. 317, no. 13, 2017, pp. 1338-48.
Among patients in the United States diagnosed with thyroid cancer from 1974-2013, the overall incidence of thyroid cancer increased 3% annually, with increases in the incidence rate and thyroid cancer mortality rate for advanced-stage papillary thyroid cancer. These findings are consistent with a true increase in the occurrence of thyroid cancer in the United States.
Carlberg, Michael, et al. “Increasing incidence of thyroid cancer in the Nordic countries with main focus on Swedish data.” BMC Cancer, vol. 16, no. 426, 2016.
The main finding of this register based study was an increasing incidence of thyroid cancer in Sweden during the whole study period 1970–2013 in both women and men, although not statistically significant in men. In both genders the incidence increased during the more recent study period, from 2001 in women and from 2005 in men.
Parotid Gland Cancers
Sadetzki, Siegal, et al. “Cellular Phone Use and Risk of Benign and Malignant Parotid Gland Tumors–A Nationwide Case-Control Study.” American Journal of Epidemiology, vol. 167, no. 4, 2007, pp. 457-67.
Our results suggest a relation between long-term and heavy cellular phone use and parotid gland tumors. This association was seen in analyses restricted to regular users, analyses of laterality of phone use, and analyses of area of main use.
Cancer and Cancer Promotion – Epidemiology
Momoli, F., et al. “Probabilistic multiple-bias modelling applied to the Canadian data from the INTERPHONE study of mobile phone use and risk of glioma, meningioma, acoustic neuroma, and parotid gland tumors.” American Journal of Epidemiology, 2017.
Since the 13-nation Interphone study was published in 2010, several methods papers have been published that reanalyze the data to correct for biases in the original paper. The authors of this study found that the risk estimate for glioma among the highest quartile of cell phone users increased after adjustment. Risk estimates for other types of head tumors did not change.

(National Toxicology Program Video Presentation that includes genotoxicity results June 2016)
Exposures to cell phone equivalent RFR began for rats in-utero and during adolescence for mice, continuing through young adulthood (subchronic) or for 2 years (chronic). Researchers observed increased incidence of gliomas as well as schwannomas in both sexes, as well as significantly more rare, pre-cancerous changes in the glial cells of the brain in both sexes, while not a single one of the unexposed control animals developed these same abnormal brain cells. Male rats exposed to all levels of CDMA developed exceptional numbers of damaged, pre-cancerous brain cells (glial hyperplasia). Body weights at birth and throughout lactation in rat pups exposed in utero tended to be lower than controls. Comet assay summaries revealed statistically significant evidence of DNA damage from nonthermal exposure in mice and rats within the frontal cortex (male & female rats, male male), hippocampus (male rats), liver (male rats, female mice), and blood (male rats, female mice). The increased types of tumors found in NTP’s research rats parallel the types of increased tumors found in human long term users of cell phones.
Lerchl, Alexander, et al. “Tumor promotion by exposure to radiofrequency electromagnetic fields below exposure limits for humans.” Biochemical and Biophysical Research Communications, vol. 459, no. 4, 2015, pp. 585-90.
Numbers of tumors of the lungs and livers in exposed animals were significantly higher than in sham-exposed controls. In addition, lymphomas were also found to be significantly elevated by exposure.

In a study examining the association between prenatal cell phone use and hyperactivity in children, researchers found that mice exposed in-utero were hyperactive and had impaired memory, and in addition, recordings of excitatory postsynaptic currents revealed that these behavioral changes were due to altered neuronal developmental programming.
Kim, Ju Hwan, et al. “Long-term exposure to 835 MHz RF-EMF induces hyperactivity, autophagy and demyelination in the cortical neurons of mice.” Scientific Reports, vol. 7, 2017.
The neuronal effects of 835 MHz RF-EMF on the cerebral cortex of the mouse brain at 4.0 W/kg for 5 hours/day for 12 weeks included induction of autophaygy genes, production of proteins, accumulation of autolysosome, demyelination in cortical neurons and hyperactivity-like behavior.
Breast Cancer Case Series Report
West JG, Kapoor NS, Liao S, Chen JW, Bailey L, Nagourney RA. (2013). Multifocal Breast Cancer in Young Women with Prolonged Contact between Their Breasts and Their Cellular Phones. Case Reports in Medicine. Volume 2013, Article ID 354682.

De Iuliis, Geoffry N., et al. “Mobile phone radiation induces reactive oxygen species production and DNA damage in human spermatozoa in vitro.” PloS one, vol. 4, no. 7, 2009.
RF-EMR in both the power density and frequency range of mobile phones (1.8 GHz covering a SAR range from 0.4 to 27.5 W/kg) were shown to enhance mitochondrial reactive oxygen species generation, decrease the motility and vitality, stimulating DNA base adduct formation and ultimately cause DNA fragmentation within the human spermatozoa
Atasoy, Halil I., et al. “Immunohistopathologic demonstration of deleterious effects on growing rat testes of radiofrequency waves emitted from conventional Wi-Fi devices.” Journal of Pediatric Urology, vol. 9, no. 2, 2013, pp. 223-9.

The results showed that prenatal EMF exposure caused a decrease in the number of granule cells in the dentate gyrus of the rats (P<0.01), suggesting that prenatal exposure to a 900 MHz EMF affects the development of the dentate gyrus granule cells in the rat hippocampus.
Sonmez, O.F., et al. “Purkinje cell number decreases in the adult female rat cerebellum following exposure to 900 MHz electromagnetic field.” Brain Research, no. 1356, 2010, pp. 95-101.
Results showed that the total number of Purkinje cells in the cerebellum of the EMFG was significantly lower than those of CG (p<0.004) and SG (p<0.002), suggesting that long duration exposure to 900 MHz EMF leads to decreases of Purkinje cell numbers in the female rat cerebellum.
Tang, Jun, et al. “Exposure to 900MHz electromagnetic fields activates the mkp-1/ERK pathway and causes blood-brain barrier damage and cognitive impairment in rats.” Brain Research, no. 1601, 2015, pp. 92-101.

Environmental Exposures Can Enhance Damage from EMFs
Kostoff, Ronald N., and Clifford GY Lau. “Combined biological and health effects of electromagnetic fields and other agents in the published literature.” Technological Forecasting and Social Change vol. 80, no. 7, 2013, no. 1331-49.
The present study examined the scope of the combined effects; i.e., identified effects on biological systems from combined exposure to electromagnetic fields/radiation and at least one other agent, concluding that EMF health impacts increase substantially when EMFs function as co-promoters and thus inclusion of co-promoters is essential for modeling real-world effects.
Byun, Yoon-Hwan, et al. “Mobile phone use, blood lead levels, and attention deficit hyperactivity symptoms in children: a longitudinal study.” PLoS One, vol. 8, no. 3, 2013.
The results suggest that simultaneous exposure to lead and RF from mobile phone use was associated with increased ADHD symptom risk, although possible reverse causality could not be ruled out.
EMF Can Interfere with Cognition

Researchers described frequency-dependent effects of mobile phone microwaves on human lymphocytes from persons reporting hypersensitivity to electromagnetic fields and healthy persons, concluding that microwaves from universal global telecommunications system (UMTS) mobile phones affect chromatin and inhibit formation of DNA double-strand breaks in human lymphocytes from both hypersensitive and healthy persons.
Yakymenko, Igor, et al. “Oxidative mechanisms of biological activity of low-intensity radiofrequency radiation.” Electromagnetic Biology and Medicine, vol. 35, no. 2, 2016, pp. 186-202.
In conclusion, our analysis demonstrates that low-intensity RFR is an expressive oxidative agent for living cells with a high pathogenic potential and that the oxidative stress induced by RFR exposure should be recognized as one of the primary mechanisms of the biological activity of this kind of radiation.

Compared to untreated controls, exposure to MF and formaldehyde causes in males a statistically significant increased incidence of malignant tumors (P ≤ 0.01), thyroid C-cell carcinomas (P ≤ 0.01), and hemolymphoreticular neoplasias (P ≤ 0.05). No statistically significant differences were observed among female groups.
Exposure Assessment Shows Greater Absorption into Younger Smaller Brains
Fernández-Rodríguez, Claudio Enrique, Alvaro Augusto Almeida De Salles, and Devra Lee Davis. “Dosimetric Simulations of Brain Absorption of Mobile Phone Radiation–The Relationship Between psSAR and Age.” IEEE Access vol. 3, 2015, pp. 2425-30.
If the peak spatial SAR (psSAR) is modeled in the entire head, as current testing standards recommend, the results for adults and children are equivalent, however the present study uses anatomically based evaluations which rely on Finite-difference time-domain simulations of different tissues within the brain, which confirm that the psSAR in a child’s brain is higher than in an adult’s brain and thus higher doses are likely to have more severe implications in the young brain.
Gandhi, Om P., et al. “Exposure limits: the underestimation of absorbed cell phone radiation, especially in children.” Electromagnetic Biology and Medicine, vol. 31, no. 1, 2012, pp. 34-51. Includes detailed history of FDA/FCC test standard evolution
Researchers indicate that the existing cell phone certification process is outdated and greatly underestimates the SAR for typical phone users, especially children, and thus call for a new certification process that incorporates different modes of use, head size, tissue properties, and anatomically based models.
Bakker, J. F., et al. “Assessment of Induced SAR in children Exposed to Electromagnetic Plane Waves Between 10 MHz and 5.6 GHz.” Physics in Medicine and Biology, vol. 55, no. 11, 2010, pp. 3115-30.
Researchers found that the basic restriction on the SAR(wb) is occasionally exceeded for children, up to a maximum of 45% in small children. The maximum SAR(10g) values, usually found at body protrusions, remain under the limit for all scenarios studied.
Ferreira, Juliana Borges, and Álvaro Augusto Almeida de Salles. “Specific Absorption Rate (SAR) in the head of Tablet users.” 7th Latin American Workshop On Communications, 2015
The psSAR simulations in heterogeneous models (adult and child) show higher levels in the children model. The possible reasons for the higher SAR estimated in the child head model compared with adult model can be due to different reasons (e.g. thinner skull, higher dielectric parameters, smaller dimensions, etc.).
