Cellphone radiation linked to rare tumors in male rats — US study

  • A US study shows that male rats exposed to high levels of cellphone radiation caused tumors around their hearts
  • The same level of RFR exposure was done to both female and male rats but only the male developed tumors
  • However, scientists said that findings could not be “directly extrapolated to humans”

Male rats exposed to very high levels of radiofrequency radiation (RFR) developed tumors in the tissues around their hearts, according to the US government’s National Institutes of Health (NIH) on Friday, February 2, as per a story posted by GMA News.

The RFR is a type of radiation which is commonly emitted by cellphones. From the preliminary report of NIH’s National Toxicology Program (NTP), rats and mice were exposed in the same level of radiation but only resulted in tumors in the tissues surrounding nerves in the heart of male rats.

However, NTP Senior Scientist Dr. John Bucher said in a written statement that findings could not be extrapolated to humans and that present safety limits on cellphone radiation are protective.

“The levels and duration of exposure to RFR were much greater than what people experience with even the highest level of cell phone use, and exposed the rodents’ whole bodies. So, these findings should not be directly extrapolated to human cell phone usage,” Bucher said.

“We note, however, that the tumors we saw in these studies are similar to tumors previously reported in some studies of frequent cell phone users,” he added.

Also, Dr. Otis Brawley, chief medical officer of the American C****r Society, stated that the studies were negative for common tumors.

“These draft reports are bound to create a lot of concern, but in fact they won’t change what I tell people: the evidence for an association between cellphones and c****r is weak, and so far, we have not seen a higher c****r risk in people,” Brawley said in a statement on Twitter.
