Abstract

Cancer occurrences in laboratory rats from exposure to RF and microwave radiation Lin JC. Cancer Occurrences in Laboratory Rats from Exposure to RF and Microwave Radiation. IEEE Journal of Electromagnetics, RF and Microwaves in Medicine and Biology. Aug 2, 2017. PP:99. Health effects of radio frequency (RF) and microwave radiation have been a subject of scientific inquiry and public interest of late because of widespread global usage of mobile communication devices by billions of people everywhere. A minute increase in health risks such as cancer from RF radiation might lead to significant consequences for health of the general public. A recent U.S. government announcement of discovery of rare cancers in rats exposed to RF radiation is an important occurrence. Note that any new or single report should not be viewed in isolation. The U.S. government project was organized to confront the weaknesses of prior laboratory rodent studies on the potential of RF exposure to impact human health such as cancer in controlled environments. Indeed, several published reports on animal cancer investigations involving prolonged exposures to RF radiation are contentious and perplexing. The discrepancies have presented ambiguity in assessing public health threats from RF exposure. It is the objective of this review to provide a critical and analytical synopsis and assessment on current progress in cancers in rats exposed, lifelong, to RF and microwave radiation. Its focus is on laboratory studies involving cancer production and promotion, and survival of experimental rats. Of special interest is carcinogenesis in the head-cancer development in the head. The question of whether RF exposure from wireless and mobile devices and systems poses a health risk would likely remain equivocal and controversial for some time to come. ieeexplore.ieee.org

Main findings

This review provides a critical synopsis of laboratory rat studies involving lifelong/prolonged RF and microwave exposures and cancer outcomes. It notes a recent U.S. government announcement of rare cancers in RF-exposed rats and states that published animal cancer reports are contentious with discrepancies, leaving assessment of public health threats from RF exposure ambiguous and equivocal.

Outcomes measured

carcinogenesis
head cancer development
cancer production and promotion
survival

Limitations

Described as a review; no specific exposure parameters (e.g., frequency, SAR) or sample sizes are provided in the abstract.
The abstract emphasizes discrepancies and ambiguity across studies, without reporting quantitative results.
