Abstract

There is evidence that electromagnetic fields (EMF) play some part in the pathogenesis of prostate cancer, but the pathogenic mechanism remains unknown. The normal prostate gland and both benign and malignant prostate lesions contain abundant calcium/phosphorus crystalloids with various morphologies, which seem to be heterogeneously and diffusely distributed within the gland. We hypothesize that an environmental EMF may result in simultaneous, multidirectional and diffuse compression or expansion of these crystalloids (a piezoelectric effect). This would result in a slight mechanical distortion of the prostate, potentially altering cell behavior and enhancing the expression of specific genes, particularly those involved in suppressing apoptosis. A mathematical model of the cell mechanical effect is presented, and the hypothesis is related to current clinical evidence and to potential validation by critical laboratory tests.

Main findings

The article proposes a hypothesis that environmental electromagnetic fields could induce multidirectional compression/expansion of calcium/phosphorus prostatic crystalloids via a piezoelectric effect, causing slight mechanical distortion that may alter cell behavior and gene expression relevant to apoptosis suppression. A mathematical model is presented and the hypothesis is linked to clinical evidence and potential laboratory validation tests.
