Radiofrequencies and cancer: this WHO monograph reshuffles the deck

Radiofrequencies and cancer: this WHO monograph reshuffles the deck
By : Phonegate Team • 29 Apr 2025

For over twenty years, the World Health Organization (WHO) has been publishing monographs assessing the risk between radiofrequencies and cancer. This new monograph, the tenth of eleven planned, marks a notable break: whereas previous monographs concluded that the risk was limited or uncertain, this one points to more robust animal evidence and highlights worrying signals for public health.

In 2011, the IARC classified radiofrequencies as “possibly carcinogenic to humans” (Group 2B), on the basis of an increased risk of glioma in intensive users of cell phones. Since then, most monographs have downplayed the risks, despite the massive increase in worldwide exposure and the proliferation of scientific studies.

Enhanced animal evidence on several tumor types

Monograph 2025 is based on 52 animal studies, including 20 long-term bioassays, and concludes that there is a high level of evidence (“high certainty”) for an increase in certain cancers in male rats exposed to radiofrequencies:

• Cerebral gliomas: significant increase in male rats exposed to high SAR (Specific Absorption Rate) levels (up to 6 W/kg).
• Cardiac schwannomas: increased risk in male rats, with dose-response effects observed in two independent long-term studies.
• Hepatoblastomas and lung tumors: significant increase in male mice exposed to CDMA (3G)-modulated radiofrequencies.
