Anses Confirms No Causal Link Between Mobile Phone Radiation and Cancer

The French National Agency for Food, Environmental and Occupational Health Safety (Anses) released a comprehensive report on November 26, 2025, concluding there is no causal relationship between mobile phone radiofrequency exposure and cancer. This assessment is based on an extensive evaluation of over 250 studies, including biological mechanisms, animal experiments, and human epidemiological data. Despite widespread public concern following the International Agency for Research on Cancer’s 2011 classification of radiofrequencies as a "possible carcinogen," Anses found the accumulated scientific evidence does not support a cancer link, even with high exposure levels.

Olivier Merckel, head of Anses' Physical Agents and New Technologies Unit, highlighted the significance of this finding given that more than 98% of people over 12 years old in France use mobile phones, which emit radiation close to the brain. While some experimental studies showed temporary cellular changes, large-scale human studies failed to demonstrate any cancer risk. Anses noted limited evidence from animal studies but recommended continued precaution, especially for children, who might be more vulnerable.

The agency advised users to minimize exposure by making calls in good reception conditions and using hands-free devices. Merckel emphasized the importance of ongoing vigilance and monitoring of radiofrequency exposure in the population to ensure public health safety remains safeguarded.
