A major scientific review commissioned by the World Health Organization (WHO) has found no evidence that mobile phone use causes brain cancer, according to a report released Wednesday. The findings could have significant implications for billions of users worldwide and for the telecommunications industry, which has long faced scrutiny over potential health risks from radiofrequency electromagnetic fields.
The WHO commissioned 13 systematic reviews in 2019 to assess whether electromagnetic waves, such as those emitted by mobile phones, have any adverse health effects. The reviews, conducted by teams of independent experts, analyzed decades of research on the topic. The results, published in the journal Environment International, concluded that there is no association between mobile phone use and brain cancer, even for heavy users.
This conclusion contradicts earlier classifications by some health agencies that labeled radiofrequency fields as “possibly carcinogenic.” The new analysis draws on a larger body of evidence and more rigorous methodology, providing greater certainty. “The findings are reassuring for the public,” said Dr. Ken Karipidis, a lead author of the review, in a statement. “They show that despite the massive increase in mobile phone use, there has been no corresponding rise in brain cancer rates.”
The study is particularly timely given the ongoing rollout of 5G networks, which have sparked renewed fears about radiation. The review included studies on various types of radiofrequency exposure, including from 5G, and found no new risks. Industry groups welcomed the results, with the Global System for Mobile Communications Association calling it “a robust scientific assessment that should help alleviate unfounded concerns.”
While the study may reduce public anxiety, experts caution that research must continue as technology evolves. Meanwhile, companies like CNS Pharmaceuticals Inc. (NASDAQ: CNSP) are focused on developing treatments for brain cancer, underscoring that the disease remains a critical health challenge. The WHO’s findings shift the focus back to prevention and treatment, rather than mobile phone risk.
For consumers, the news means that current safety guidelines for mobile phone radiation levels are likely adequate. However, users who remain concerned can still take simple steps, such as using hands-free devices or limiting call duration. The full review is available on the WHO website.
