The most comprehensive study on a topic that’s played to our greatest fear for years.

Does the radiation from your cell phone cause cancer?


The Study

  • 10-year study by the National Institutes for Health’s National Toxicology Program.
  • Rodents (rats/mice) were exposed to varying levels of radio frequency radiation (the same radiation used by certain cell phones) for 9 hrs a day for 2 yrs.
  • Lowest radiation exposure was equal to our cell phones; highest was 4x legal amount for humans.


“… clear evidence that male rats exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones developed cancerous heart tumors.”

Researchers say they believe the link between radiation & tumors is “real“, however, they also admit that results are not the same for female rats, or male/female mice.


“In our studies, rats and mice received radio frequency radiation across their whole bodies. By contrast, people are mostly exposed in specific local tissues close to where they hold the phone.”

John Bucher, Ph.D., NTP senior scientist of study explaining one reason why the study can't be applied directly to humans, but also why more research is needed.

“An important lesson that should be learned from the NTP studies is that we can no longer assume that any current or future wireless technology, including 5G, is safe without adequate testing.”

Dr. Ronald Melnick who says the FDA's response to the study is inadequate. The FDA disagrees with conclusion that there is "clear evidence" of a link between radio frequency radiation & tumors. Melnick says rodents weren't exposed to radiation that much higher than humans on cell phones.

Researchers say their results do NOT apply to 4G - 5G networks expected to debut over the next few years. According to one research firm, Americans check their phone on average of every 12 min and look at our phone at least 80 times / day. Tips to reduce your exposure:
