United States: National Toxicology Program Releases Draft Cancer Report

From Abstract of draft report:  "The US National Toxicology Program (NTP) has carried out extensive rodent toxicology and carcinogenesis studies of radiofrequency radiation (RFR) at frequencies and modulations used in the US telecommunications industry. This report presents partial findings from these studies. The occurrences of two tumor types in male Harlan Sprague Dawley rats exposed to RFR, malignant gliomas in the brain and schwannomas of the heart, were considered of particular interest, and are the subject of this report."  [Abstract is below, with access to draft report in full.]

NTP Releases Draft Cancer Report
Microwave News, 27 May 2016

This evening, the NTP released a draft of the report on its two-year cell phone cancer study.Linda Birnbaum, the director of the NIEHS, and John Bucher, the leader of the study, will present the report at a teleconference tomorrow, Friday. They are the director and associate director of the NTP, respectively.

The report that was posted only covers rats. The accompanying study of mice found no effects on cancer.

For a copy of the report, go to bioRxiv.org.

Abstract

The US National Toxicology Program (NTP) has carried out extensive rodent toxicology and carcinogenesis studies of radiofrequency radiation (RFR) at frequencies and modulations used in the US telecommunications industry. This report presents partial findings from these studies. The occurrences of two tumor types in male Harlan Sprague Dawley rats exposed to RFR, malignant gliomas in the brain and schwannomas of the heart, were considered of particular interest, and are the subject of this report. The findings in this report were reviewed by expert peer reviewers selected by the NTP and National Institutes of Health (NIH). These reviews and responses to comments are included as appendices to this report, and revisions to the current document have incorporated and addressed these comments. Supplemental information in the form of 4 additional manuscripts has or will soon be submitted for publication. These manuscripts describe in detail the designs and performance of the RFR exposure system, the dosimetry of RFR exposures in rats and mice, the results to a series of pilot studies establishing the ability of the animals to thermoregulate during RFR exposures, and studies of DNA damage.
