In this review we discuss alarming epidemiological and experimental data on possible carcinogenic effects of long term exposure
to low intensity microwave (MW) radiation. Recently, a number of reports revealed that under certain conditions the irradiation
by low intensity MW can substantially induce cancer progression in humans and in animal models. The carcinogenic effect of MW irradiation
is typically manifested after long term (up to 10 years and more) exposure. Nevertheless, even a year of operation
of a powerful base transmitting station for mobile communication reportedly resulted in a dramatic increase of cancer incidence
among population living nearby. In addition, model studies in rodents unveiled a significant increase in carcinogenesis after
17-24 months of MW exposure both in tumor-prone and intact animals. To that, such metabolic changes, as overproduction of reactive
oxygen species, 8-hydroxi-2-deoxyguanosine formation, or ornithine decarboxylase activation under exposure to low intensity
MW confirm a stress impact of this factor on living cells. We also address the issue of standards for assessment of biological
effects of irradiation. It is now becoming increasingly evident that assessment of biological effects of non-ionizing radiation based
on physical (thermal) approach used in recommendations of current regulatory bodies, including the International Commission
on Non-Ionizing Radiation Protection (ICNIRP) Guidelines, requires urgent reevaluation. We conclude that recent data strongly
point to the need for re-elaboration of the current safety limits for non-ionizing radiation using recently obtained knowledge. We also
emphasize that the everyday exposure of both occupational and general public to MW radiation should be regulated based on a precautionary
principles which imply maximum restriction of excessive exposure.
Key Words: non-ionizing radiation, radiofrequency, tumor, risk assessment, safety limits, precautionary principle.
