Recent research has put to rest concerns about mobile phones and their potential link to brain cancer. A comprehensive review by the World Health Organization (WHO) has found no evidence supporting the notion that mobile phone use increases the risk of brain cancer. This conclusion is drawn from a wide analysis of global studies and offers reassurance to millions of mobile phone users worldwide.
Extensive Review of Global Studies
The WHO's extensive review, published in Environment International, is based on an examination of 63 studies conducted from 1994 to 2022. This research incorporated the expertise of 11 professionals from ten different countries, including specialists from Australia’s radiation protection authority. The studies reviewed covered a broad spectrum of research concerning the potential health impacts of radiofrequency radiation emitted by mobile phones and other devices like televisions and baby monitors.

No Increased Risk Identified
The review's findings are clear: there is no substantial evidence linking mobile phone usage to an increased risk of brain cancer. This conclusion remains consistent even for individuals who frequently engage in lengthy phone conversations or have been using mobile phones for extended periods, including over a decade. Mark Elwood, a co-author of the study and professor of cancer epidemiology at the University of Auckland, emphasized that none of the examined cancer types, including brain cancers in both adults and children, showed any significant association with mobile phone use.

Broader Scope of Analysis
The study’s scope extended beyond just brain cancer, encompassing other types of cancer such as those affecting the pituitary gland, salivary glands, and even leukaemia. It also assessed potential risks associated with mobile phone base stations, transmitters, and exposure in various work environments. This comprehensive approach ensures that the findings are robust and cover multiple facets of radiofrequency exposure.
Reassurance from Researchers
The research team, including Sarah Loughran and Ken Karipidis, communicated their findings in The Conversation, noting that the results are reassuring. They highlighted that mobile phones emit radio waves at levels well below established safety limits, and current data indicates that these levels do not adversely affect human health. This supports the existing national and international safety standards designed to protect users.

Consistency with Previous Research
This review aligns with earlier research, which has consistently found no conclusive evidence linking mobile phone radiation to health issues. The International Agency for Research on Cancer (IARC) has classified mobile phone radiation as "possibly carcinogenic" or Class 2B. This classification reflects the potential for risk but does not confirm a direct link. Given the new data, the IARC's advisory group has suggested that a re-evaluation of this classification may be necessary.
Implications for Future Research
Despite these reassuring findings, the scientific community remains vigilant. The IARC’s classification indicates that while current evidence does not support a definitive link between mobile phone use and cancer, the potential for future discoveries means continued research is important. The latest data might influence future assessments and provide clearer insights into the long-term effects of radiofrequency exposure.
Bottomline
In summary, the latest global study confirms that mobile phones do not increase the risk of brain cancer. This finding is based on a rigorous analysis of numerous studies and provides a strong foundation for public reassurance. While the IARC’s classification suggests a need for ongoing research, the current evidence supports the safety of mobile phone use with respect to cancer risk.
