RF was classified as a Group 2B Possible Human Carcinogen (IARC/WHO) in 2011. This was based on higher brain tumour rates (glioma and acoustic neuroma – a type of Schwannoma) found in longer term mobile phone users. Since then, the evidence for cancer from RF has elevated.
The US National Toxicology Program (2018) found ‘Clear Evidence’ for heart Schwannoma in animals exposed to RF and ‘some evidence’ of several other cancers including glioma. Compounding this, the Ramazzini Institute found Schwannomas again even though they used lower intensity far-field radiation like that produced by base stations.
Together these multiple forms of evidence elevate the carcinogenic status of RF but IARC have not yet reconvened to reclassify it.
Experts are calling for it now to be a Group 1 Known Human Carcinogen like tobacco, asbestos or x-rays.
