Comments on the US National Toxicology Program technical reports on toxicology and carcinogenesis study in rats exposed to whole-body radiofrequency radiation at 900 MHz and in mice exposed to whole-body radiofrequency radiation at 1,900 MHz

Abstract

Overview

During the use of handheld mobile and cordless phones, the brain is primarily targeted by radiofrequency (RF) radiation. The International Agency for Research on Cancer (IARC) at the World Health Organization (WHO) classified RF radiation in the frequency range of 30 kHz-300 GHz as a 'possible' human carcinogen, Group 2B, in May 2011, based predominantly on human epidemiological studies.

Findings

• An increased risk of developing glioma and acoustic neuroma has been observed in these studies.
• Evidence from animal studies, including those from 1982 and the recent Ramazzini Institute rat study, supports carcinogenic potential in RF radiation.
• The US National Toxicology Program (NTP) studies revealed an increased incidence of glioma in the brain and malignant schwannoma in the heart.

Conclusion

The reviews and comparisons of previous epidemiological studies to the latest NTP findings suggest clear evidence that RF radiation is a human carcinogen, contributing to glioma and vestibular schwannoma (acoustic neuroma). Additionally, there's some evidence of an increased risk of developing thyroid cancer and clear evidence supporting the classification of RF radiation as a multi-site carcinogen.

Based on the IARC Monographs' Preamble, RF radiation should be classified as carcinogenic to humans, Group 1.
