The National Toxicology Program (NTP) concluded there is “clear evidence” that male rats exposed to high levels of RF radiation like that used in cell phones developed cancerous heart tumors, according to a report released on November 1st 2018.[i]

There was also “some evidence” of tumors in the brain and adrenal gland of exposed male rats.

The $30 million NTP studies took more than 10 years to complete and are the most comprehensive assessment, to date, of health effects in animals exposed to RF radiation emitted by cell phones.

Although animal studies can’t perfectly replicate human cell phone use, the 2011 INTERPHONE study also found that the heavy cell phone users were more likely to develop glioma[ii] — the same type of brain cancer the NTP study found in the male rats.

Ronald Melnick, the NTP senior toxicologist who designed the studies, believes the FDA should issue guidance based on the results of the research. “I would think it would be irresponsible to not put out indications to the public,” Melnick says. “Maintain a distance from this device from your children. Don’t sleep with your phone near your head. Use wired headsets. This would be something that the agencies could do right now.”
