Your cellphone can give you cancer, suggests a $25 million study conducted by the National Toxicology Program (NTP), a branch of the National Institutes of Health.
The study, which exposed more than 2,500 rats for two years to the type of radiation you're exposed to every time you use your cellphone, increased the numbers of two types of deadly tumors — gliomas, a type of cancerous brain tumor, and malignant schwannomas, an extremely rare tumor of the heart.
The rats were exposed to different levels of radiation: The highest was up to seven times the amount human usually receive when using a phone. Rats had a significantly higher risk of developing gliomas and also an increased risk of schwannomas. "There was a significant dose-response relationship," a source told microwavenews.com.
Previous studies have also found links to cancer. A 2015 meta analysis based on a review of 100 studies, found that the low-intensity radiofrequency radiation (RFR) cellphones emit has an effect on living cells and can damage DNA.
RF energy was classified as "possibly carcinogenic" in 2011 by the International Agency for Research on Cancer.
Even so, the FDA said there was no real evidence that cellphones caused cancer. The new study may force them to reconsider their conclusion. The researchers wrote that the results "appear to support" the conclusion that the cancer risk is real.
"Given the widespread global usage of mobile communications among users of all ages, even a very small increase in the incidence of disease resulting from exposure to [radio-frequency radiation] could have broad implications for public health," the study authors wrote, according to a report of partial findings from the study.
The findings should be a wake-up call for the scientific establishment, Chris Portier, former associate director of the NTP, who commissioned the study, told Mother Earth. Portier is now a contributing scientist at the Environmental Defense Fund.
"I think this is a game changer," he said. "We seriously have to look at this issue again in considerable detail."
"The NTP does the best animal bioassays in the word," Portier told Mother Earth. "Their reputation is stellar. So if they are telling us this was positive in this study, that's a concern."
