A model for possible effects of electromagnetic fields on the occurrence of cancer

A model has been developed for explaining the possible effects of electromagnetic fields on the occurrence of cancer.´ This model postulates that electromagnetic fields increase the cell division rate and therefore the occurrence of natural or spontaneous cancers, e.g. those produced by radiation or chemicals. The increased cell division rate may occur because the biological system is able to perceive the presence of the electromagnetic field but is probably not able to identify it, at least not at low field strengths. The unidentified stimulus produces a physiological stress that increases the cell division rate. This model is consistent with most observations and can be used to make predictions.
