Cell phone radiation linked to cancer

The study found that 2 to 3 percent of the exposed male rats developed malignant gliomas, a deadly brain cancer. Among the female mice, however, the evidence was unclear as to whether the cancers observed in them are associated with RFR.

In the NTP studies, the report notes, exposure was way more than what happens through average duration of cellphone usage. Yes, cell phone radiation was linked to cancer in a new study, according to BuzzFeed News, but before you freak out, you should know that even the authors of the study are saying it's nothing to worry about.

"In our studies, rats and mice received radio frequency radiation (RFR) across their whole bodies". By contrast, people are mostly exposed in specific local tissues close to where they hold the phone. But he cautioned that the exposure levels and durations were far more significant than what people typically encounter, and thus can not "be compared directly to the exposure that humans experience".

At the exposure's lowest levels, it was equal to the maximum local tissue exposure allowed for mobile phone users, a level that rarely occurs during typical phone use. The highest level was four times higher than the permitted maximum.

"We believe that the link between radio frequency radiation and tumours in male rats is real", Bucher noted.

The finding was the result of a $30 million 10 year study to assess the health effects in animals exposed to RFR with modulations used in 2G and 3G cell phones.

These studies did not investigate the types of RFR used for Wi-Fi or 5G networks.

During testing, the animals were housed in a chamber, with exposure to RFR beginning in the womb for rats and at least five weeks old in mice for up to two years, or the duration of their lives. For the rats, the exposures started before birth and continued until they were about two years old.

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. Most phones still contain antennas that can pick up these frequencies, but rely more heavily on newer generation technology like 4G LTE and 5G, which is being rolled out across the US. "From what we now understand, it likely differs dramatically from what we studied", said Michael Wyde, lead toxicologist on the studies. These studies will focus on developing measurable physical indicators, or biomarkers, of potential effects from RFR. These may include changes in metrics like DNA damage in exposed tissues, which can be detected much sooner than cancer.

"Animal studies like this one contribute to our discussions on this topic, but we must remember the study was not created to test the safety of cellphone use in humans, so we can not draw conclusions about the risks of cellphone use from it", Dr. Jeffrey Shuren, director of the Food and Drug Administration's Center for Devices and Radiological Health, who was not involved with the study, said in a statement.

The lowest exposure level used in the studies was equal to the maximum local tissue exposure now allowed for cell phone users and this power level rarely occurs with typical cell phone use, according to the reports.

Dr. Ronald Melnick designed the exposure systems used in the study before his retirement from the National Institute of Environmental Health Sciences. For more information about NTP and its programs, visit https://ntp.niehs.nih.gov.

Now, the organization is back with more worrying news.
