Experts Find "Clear Evidence" of Cancer from Cell Phone Radiation in National Toxicology Program Study

National Toxicology Program: Peer & public review of cell phone radiation study reports

Experts find "clear evidence" of cancer from cell phone radiation in NTP study
saferemr.com, 28 March 2018

Eleven experts convened by the National Toxicology Program (NTP) over a three day period to review the draft technical reports from the NTP's cell phone radiation studies concluded that there is "clear evidence" that exposure to cell phone radiation caused a rare cancer in the hearts of male rats, and "there is equivocal evidence" for the hearts of female rats.

The expert panel also reported "some evidence" that cell phone radiation exposure caused brain cancer in male and female rats and cancer of the adrenal glands in male rats.

Additionally, "equivocal evidence" of cancer risk was reported in the pituitary, adrenal, and prostate glands and pancreas and liver in male rats and adrenal glands in female rats.

The mice in the study, exposed to a different cell phone radiation frequency than the rats (1800 MHz vs. 900 MHz), displayed less evidence of cancer risk. Equivocal evidence of cancer risk from cell phone radiation was reported for lymphoma in male and female mice. Equivocal evidence was also reported for skin, lung, and liver cancer in male mice.

In seven instances, the expert group upgraded the evaluations of evidence published by NTP staff in the draft technical reports. Thus, the NTP scientists appear to have been overly conservative in their assessment of the hazards of long-term exposure to cell phone radiation.

A table which compares the evaluations of evidence of carcinogenicity prepared by NTP staff with the expert committee's findings is available at:

Definitions

Clear Evidence of Carcinogenic Activity is demonstrated by studies that are interpreted as showing a dose-related (i) increase of malignant neoplasms, (ii) increase of a combination of malignant and benign neoplasms, or (iii) marked increase of benign neoplasms if there is an indication from this or other studies of the ability of such tumors to progress to malignancy.

Some Evidence of Carcinogenic Activity is demonstrated by studies that are interpreted as showing a chemical-related increased incidence of neoplasms (malignant, benign, or combined) in which the strength of the response is less than that required for clear evidence.

Equivocal Evidence of Carcinogenic Activity is demonstrated by studies that are interpreted as showing a marginal increase of neoplasms that may be chemically related.

No Evidence of Carcinogenic Activity is demonstrated by studies that are interpreted as showing no chemical-related increases in malignant or benign neoplasms.

Note: Although the definitions typically are applied to chemical agents, NTP also uses them with physical agents like cell phone radiation.
