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.
ICBE-EMF highlights that in 2011, the World Health Organization’s International Agency for Research on Cancer (IARC) classified radiofrequency radiation (RF-EMF) as a Group 2B “possible” human carcinogen, noting limited animal evidence. Since then, major animal studies — including those by the U.S. National Toxicology Program and the Ramazzini Institute — have found that RF radiation exposure causes cancer in rats.
The new WHO-funded review, concluding there is “high certainty” animal evidence of cancer causation, reinforces calls for IARC to urgently reevaluate the cancer classification of RF radiation.
A study funded by the World Health Organization, concluded 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...
