Radiofrequency radiation: carcinogenic and other potential risks
Several epidemiological studies reported associations of radiofrequency radiation (RFR) exposures with glioma, acoustic neuroma, and other tumors. Other research did not indicate such associations or reported a reduced cancer risk. Epidemiological research is known to be associated with selection and recall bias. A moderate incidence increase of certain tumors has been out of proportion to the rapid expansion of mobile phones, being explainable by improvements in the diagnostic imaging. In some experiments, RFR was associated with the incidence increase of certain age-related tumors but, at the same time, with a longer survival of exposed animals. Potential thermal and non-thermal effects of RFR are overviewed here. In conclusion, there is neither convincing evidence nor theoretic plausibility of a cause-effect relationship between RFR and cancer. Reliable evidence can be obtained by large-scale animal experiments. To make experiments less expensive, it would suffice to maintain large animal groups in equal conditions and to record the life span.
