A former Ramazzini Institute scientific director describes animal RF cancer findings, compares them with …

I was Scientific Director and Scientific Advisor of the Ramazzini Institute in Bologna until 2023, now retired. From 1981 to 2001, I worked closely with Professor Cesare Maltoni, an internationally renowned oncologist; then I was Scientific Director of the same Institute. I am expert in the study of agents that can determine cancers and other environmental pathologies; among them ionizing radiation, low frequency electromagnetic fields (ELFEMF) and radio frequency electromagnetic fields (RF-EMF). I paid particular attention to the issue of the risks related to simultaneous exposure even to small doses of chemicals or physical agents, alone or associated to multiple exposures, especially during embryonic and foetal life, as well as in childhood. I am the principal investigator of the RF-EMF large study performed by the Ramazzini Institute since 2006 up to the publication of data. We published the results of the carcinogenicity study in 2018 (Falcioni et al, 2018)1, when the US NIEHS/NTP technical report on RF-EMF (NTP, 2018)2 was also published. And, surprisingly, using the same experimental model, we obtained the same results: a statistically significant increase in heart schwannomas and an increase in brain gliomas (statistically significant in the NTP study). We studied very low SAR (Specific Absorption Rate) levels, simulating human exposures to radio base station antennas, the NTP studied SAR much higher, and in this case the exposure responses were higher. The two studies were evaluated in the systematic review commissioned by WHO (Mavissen et al, 2025)3 , which concludes.: “The findings of this systematic review indicate that there is evidence that RF EMF exposure increases the incidence of cancer in experimental animals with the CoE being strongest for malignant heart schwannomas and gliomas.” Based on the experimental results cited, and due to the enormous diffusion of radio frequency technologies, I am strongly and scientifically convinced that in assessing risks to the human population, policy makers must at least adopt a principle of caution by lowering exposure to limits compatible with the health of thI was Scientific Director and Scientific Advisor of the Ramazzini Institute in Bologna until 2023, now retired.
