Morphological and cytophysiological changes in selected lines of normal and cancer human cells under the influence of a radio-frequency electromagnetic field. 2021.

Very thorough study and introduction. “The presented study shows that an RF electromagnetic field has a significant influence on cell metabolic activity. The results of the viability analysis of cells exposed to the electromagnetic field unambiguously indicate that normal human fibroblast cells decrease metabolic activity, while the survival of cancer cells (PC-3) increases in relation to an increase in RF-EMF incubation time. On the basis of the obtained results, the hypothesis can be formulate that a high frequency electromagnetic field can have harmful effects on human cells.”

An increased risk of certain tumours with mobile phone use – researchers call for upgrade of RFR from a Group 2b possible human carcinogen to a Group 1 known carcinogenAnthony B. Miller, L. Lloyd Morgan, Iris Udasin and Devra Lee Davis. “Cancer Epidemiology Update, following the 2011 IARC Evaluation of Radiofrequency Electromagnetic Fields (Monograph 102)”  Environmental Research, 2011This review demonstrates  an increased risk of brain, vestibular nerve and salivary gland tumours associated with mobile phone use. The conclusion of the researchers was that, based on the evidence reviewed, IARC’s current categorization of RFR as a possible human carcinogen (Group 2B) should be upgraded to Carcinogenic to Humans (Group 1).
Clear evidence of tumours – malignant schwannomas and gliomas – in the hearts of male rats from near-field RFR (eg mobile phones)National Toxicology Program (NTP) Carcinogenesis Studies of Cell Phone Radiofrequency Radiation, Final Reports 2018The very important findings of the 10 year $30 million NTP studies found that high exposure to RFR used by cell phones was associated with:1) Clear evidence of tumours in the hearts of male rats. The tumours were malignant schwannomas.2) Some evidence of tumours in the brains of male rats. The tumours were malignant gliomas.3) Some evidence of tumours in the adrenal glands of male rats. The tumours were benign, malignant, or complex combined pheochromocytoma. 
The prestigious Ramazzini Institute findings, of tumours in rats exposed to far-field RFR (ie from masts), support the findings of the NTP studyBelpoggi et al. (Ramazzini Institute), “Report of final results regarding brain and heart tumors in Sprague-Dawley rats exposed from prenatal life until natural death to mobile phone radiofrequency field representative of a 1.8 GHz base station environmental emission” 2018“Our findings of cancerous tumours in rats exposed to environmental levels of RF are consistent with and reinforce the results of the US NTP studies on cell phone radiation, as both reported increases in the same types of tumours of the brain and heart in Sprague-Dawley rats. Together, these studies provide sufficient evidence to call for the International Agency for Research on Cancer (IARC) to re-evaluate and re-classify their conclusions regarding the carcinogenic potential of RFR in humans” 
Meningioma and glioma in the temporal lobe can be considered to be caused by cumulative RF exposureCarlberg, Michael and Hardell, Lennart  “Evaluation of Mobile Phone and Cordless Phone Use and Glioma Risk Using the Bradford Hill Viewpoints from 1965 on Association or Causation.”2017When considered vis a vis deductive public health principles, the combined evidence from epidemiology and laboratory studies indicates 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.
Tumours in lungs and liver, and lymphomas, elevated by exposure to RFRLerchl, Alexander, et al. “Tumor promotion by exposure to radiofrequency electromagnetic fields below exposure limits for humans.”  2015Numbers 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.
