[en] The debate over the suspected link between Extremely Low Frequency (ELF) magnetic fields and cancer is entering its second decade, but the end is not in sight. The epidemiological evidence is now somewhat stronger, mainly due to the Savitz study of residential exposure and childhood cancer, but far from overwhelming. The results of in-vitro studies are fragmentary, sometimes contradictory and, overall, confusing. Well designed animal studies are virtually non-existent. A plausible biological model has not yet been established. Although scant, the present body of knowledge is very complex encompassing several disciplines and this workshop brought together researchers of vastly different backgrounds. The nine papers presented deal with an overview of ELF and cancer; the biochemistry of processes implicated in ELF carcinogenesis; possible mechanisms of cancer promotion; the status of in-vitro ELF cellular interactions; epidemiological studies, both occupational and residential, and the use of wire coding configurations as indicators of magnetic field exposures in such studies. Discussion follows each paper. Refs., figs., tabs
