ABSTRACT
Consideration of a possible causal relationship between mobile phone use and brain cancer risk leads naturally to the question, “Has the incidence of brain cancer increased since the introduction and explosive growth in use of mobile phones?” There would, of course, be a lag of some extent, albeit unknown, depending on the time course of the pathogenesis of the cancer, and its detection, diagnosis, and documentation in a population-based cancer registry. Nonetheless, the increase in use of mobile phones has been so dramatic, and the prevalence of use in the general population is now so high, that it is implausible that any substantial increase in brain cancer risk would not eventually be reflected in population incidence rates.
