Scientific Experts Urge the FCC to Establish Science-Based Exposure Limits to Address Wireless Health Risks
WASHINGTON, DC / ACCESS Newswire / April 29, 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.
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.
Given this high level of certainty, government policymakers worldwide should immediately move to revise their RF radiation exposure limits to protect public health and the environment.
Statements by Experts of the International Commission on the Biological Effects of Electromagnetic Fields
"The evidence is now clear - cell phone radiation can cause cancer in animals in concordance with the tumor types identified in human studies of mobile phone users. As animal studies are essential for predicting cancer risk in humans, governments should develop science-based safety standards to protect human health. The conclusion of the study commissioned by the WHO shows that the long-standing assumption current government limits are based on - that cell phone RF radiation can only cause harm through tissue heating - is wrong" stated Ron Melnick, PhD, Chair of the ICBE-EMF and former senior toxicologist and Director of Special Programs at the National Toxicology Program and the National Institute of Environmental Health Sciences (NIEHS).
"The preponderance of the research published since 1996 finds adverse biologic and health effects from long-term exposure to low levels of modulated or pulsed wireless RF radiation. Given the widespread global usage of wireless among users of all ages, even a very small increase in the incidence of disease will have broad implications for public health," stated said Joel Moskowitz, PhD, Director of the Center for Family and Community Health at the School of Public Health, University of California, Berkeley, also an ICBE-EMF member.
"To protect public health and the environment, exposure to cell phone and wireless radiation must be significantly reduced," said Elizabeth Kelley, Managing Director of ICBE-EMF. She referenced the EMF Scientist Appeal now signed by 267 scientists from 45 nations. "Hundreds of scientists worldwide agree that current exposure limits are outdated and do not adequately protect against health risks."
ICBE-EMF emphasizes that governments must act immediately to strengthen regulatory limits on wireless radiation to protect public health. Wildlife exposures must be mitigated. Current exposure standards, based on outdated assumptions, do not reflect the scientific evidence linking RF radiation to cancer and other health effects.
ICBE-EMF also highlights practical steps the public can take to reduce exposure - such as using speakerphone or wired headsets, keeping devices away from the body, and limiting wireless use among children - but stresses that personal actions are not a substitute for government-enforced safety standards. Stronger, science-based regulations are urgently needed to address the widespread and increasing exposure to wireless radiation.
About the ICBE-EMF
ICBE-EMF is an international consortium of scientists, doctors and researchers with expertise and peer-reviewed publications on the biological and health effects of electromagnetic fields including wireless RF radiation. Wireless devices such as cell phones, cordless phones, Wi-Fi and cell towers emit radiofrequency (RF) radiation.
ICBE-EMF recently published major scientific papers concluding that current government safety limits for wireless radiation are not protective of public health and highlighting engineering solutions that could dramatically reduce radiation emissions from cell phones.
The Commission is committed to upholding the highest standards of scientific research and makes science-based recommendations to ensure the protection of the public and environment. icbe-emf.org
