Cellphones, Increased Cancer Risk Linked in Rats

Cellphones, Increased Cancer Risk Linked in Rats

The findings are unlikely to satisfy many people.

Now, it says it will echo the NTP's previous advice to the public, back in February when the preliminary results were revealed. The body parts nearest the antenna can absorb this energy, says the NCI, which has created concerns about increased risks of developing cancer (and particularly brain cancer).

While his agency said the risks to rats don't directly apply to people, the study raises safety questions.

The National Toxicology Program is an inter-agency programme headquartered at the National Institutes of Health.

The results involve radio frequencies long out of routine use, and the Food and Drug Administration disagrees with the conclusions. In general, Bucher said, they advised the NTP to strengthen its confidence in what was found. (The female rats and mice did not show evidence of a link between the radiation and such tumors.) Two panel members, Lydia Andrews-Jones, of Allergan, and Susan Felter, of Procter & Gamble, proposed the risk upgrade.

Unexpectedly, the study also found that, overall, the male rats exposed to the cellphone radiation lived longer than the rats who were not exposed to the radiation.

It's still not clear why either thing might happen.

What did the new study find? And mice were not as strongly affected as rats seemed to be. "From what we now understand, it likely differs dramatically from what we studied", said Wyde.

"Not carrying the phone in your trousers, or your bra or your shirt pocket, and not allowing children to use cellphones, because they're most vulnerable to this radiation; it penetrates deeper into their bodies", says Scarato.


However, those thinking this is about to blow the lid on the mobile phone industry will need to think again, as the researchers stressed that "exposures used in the studies can not be compared directly to the exposure that humans experience when using a cell phone". "In addition, the exposure levels and durations in our studies were greater than what people experience", added Bucher.

According to Dr. Jeffrey Shuren, the U.S. FDA's director for Devices and Radiological Health, such animal studies are important in the discussion, but it was not created to test the safety of cellphones in humans and could therefore not be used to draw conclusions for humans. "These findings should not be applied to human cellphone usage", Dr. Jeffrey Shuren, FDA's chief of radiological health, said Thursday.

He said the data from the study was confusing and contradictory. "That is the absolute most important scientific fact".

"The US IEEE-FCC human safety guidelines for wireless radiation which only protect against thermal heating or burning were scientifically false decades ago". Other animal studies have found less dire effects at lower cell radiation levels, or more extreme effects in small animal studies using high radiation levels.

"I'm calling you from my cellphone", noted the cancer society's Brawley. We believe the existing safety limits for cell phones remain acceptable for protecting the public health'.

People can be exposed to radiofrequency radiation from cellphone towers, the report notes, but it's much more diffuse than what people get from using a cellphone.

As for Bucher, he says he's not a heavy cellphone user himself.

"I have become, based on these studies, a little more aware of my use of cellphones and if I make a short call I have absolutely no hesitation at all in picking up the phone and using it in a traditional manner", he said.
