Press Release April 27, 2025
Environment International has published a new systematic review, partially funded by the World Health Organization, concluding that there is high certainty of the evidence linking cell phone radiofrequency (RF) radiation to two types of cancer in animals. In response, leading scientists from the International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) are calling for immediate policy action to protect public health and the environment, warning that further delay could have serious consequences amid the global surge in the use of wireless communication devices.
What the Review Found
A new systematic review of 52 animal studies, “Effects of Radiofrequency Electromagnetic Field Exposure on Cancer in Laboratory Animal Studies” by Mevissen et al. (2025), concluded there is high certainty of the evidence linking RF radiation exposure to two types of tumors: gliomas in the brain and malignant schwannomas in the heart. Notably, the same types of tumors have also been observed in human studies, adding significant confidence that the associations observed in human studies are real.
The review also found moderate certainty of evidence of an increased risk of rare tumors, such as pheochromocytomas in the adrenal glands and hepatoblastomas in the liver. Additionally, some studies indicated a possible association with lymphomas, although the findings were inconsistent.
