Researchers find link between cell phones and cancer

The news and stories that matter, delivered weekday mornings.

Senior scientist Dr John Bucher at the National Toxicology Programme in Durham, North Carolina said: "The exposures used in the studies can not be compared directly to the exposure that humans experience when using a cell phone". The findings are unlikely to satisfy many people.

The NTP study proved wireless radiation can cause cancer and it can damage our DNA which can lead to a host of serious diseases. It found there is evidence that bathing rats in certain types of cellphone radiation for their entire lives might raise the risk of certain cancers in some of the rats.

But the Food and Drug Administration (FDA) insists that the danger does not apply to humans.

While the FDA says that the smart and cell phones we spend hours with every day pass its muster, some experts warn the FCC should take pause before the auction day in light of the NTP's final report. In general, Bucher said, they advised the NTP to strengthen its confidence in what was found. In February, the NTP said there was some evidence this happened but now says the evidence is clear.

For female rats and mice of both sexes the evidence was less clear as to whether cancers observed were associated with signal exposure. This will help guide scientists in targeting their future research.

Rat studies often find cancer links that never show up in people. And mice were not as strongly affected as rats seemed to be.

The lowest exposure level used for the study was equal to the maximum local tissue exposure now allowed for cellphone users, the report states.

And since 1999, it has been a concern to the National Institutes of Health (NIH), too, prompting the agency to dedicate $30 million to the NTP to study the link.

The rats were exposed to radiation at a frequency of 900 megahertz, the frequency used in the second generation of mobile phones that prevailed in the 90s when the study was first conceived. By contrast, people are mostly exposed in specific local tissues close to where they hold the phone.

The lowest level of radiation was equivalent to the maximum level that cellphones are allowed to emit in the U.S. But the researchers noted that a typical cellphone user rarely ever reaches this level. "Of course, people who are concerned about the risk can always choose to use a headset or similar device when using a mobile phone, so that any possible risk - however small or unlikely - can be completely avoided".

But the FDA has already taken issue with the findings.

"As scientists, we welcome new studies", Shuren said.

To see if radiation itself - not heat from cell phones - could cause cancer, they exposed male and female rats and mice to full-body RFR at levels far higher than we experience from our phones.

Some scientists have warned that 5G - which uses milimeter waves, rather than the microwaves that were the basis of previous generations - may in fact be more unsafe, but its far too soon to tell for sure.

Overall, "the totality of the available scientific evidence continues to not support adverse health effects in humans caused by exposures at or under the current radio-frequency energy exposure limits", Shuren said. We believe the existing safety limits for cell phones remain acceptable for protecting the public health'.

"We note NTP's own assessment that today's report can not be extrapolated to human cell phone usage, and the Food and Drug Administration's concurrence that "these findings should not be applied to human cell phone usage" and that 'the existing safety limits for cell phones remain acceptable for protecting the public health.' These conclusions are consistent with official federal brain tumor statistics showing that since the introduction of cellphones in the mid-1980s, the rate of brain tumors in the United States has decreased".

As for Bucher, he says he's not a heavy cellphone user himself. There is debate regarding the potential hazards of cellphone use because of radiation, but there is still no conclusive evidence of cellphone radiation harm among humans.
