“Game-Changing” Study Links Cellphone Radiation to Cancer An increased incidence of brain and heart tumors was seen in rats. Mother Jones, MAY 27, 2016 It’s the moment we’ve all been dreading. Initial findings from a massive federal study, released on Thursday, suggest that radio-frequency (RF) radiation, the type emitted by cellphones, can cause cancer.
The findings from a $25 million study, conducted over two and a half years by the National Toxicology Program (NTP), showed that male rats exposed to two types of RF radiation were significantly more likely than unexposed rats to develop a type of brain cancer called a glioma, and also had a higher chance of developing the rare, malignant form of tumor known as a schwannoma of the heart. The effect was not seen in females.
he radiation level the rats received was “not very different” from what humans are exposed to when they use cellphones, said Chris Portier, a former associate director of the NTP who commissioned the study.
As the intensity of the radiation increased, so did the incidence of cancer in the rats. (The highest radiation level was five to seven times as strong as what humans typically receive while using a phone.) Although ionizing radiation, which includes gamma rays and X-rays, is widely accepted as a carcinogen, the wireless industry has long noted that there is no known mechanism by which RF radiation causes cancer. The researchers wrote that the results “appear to support” the conclusion that RF radiation may indeed be carcinogenic.
The findings should be a wake-up call for the scientific establishment, according to Portier, who 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 added. “Their reputation is stellar. So if they are telling us this was positive in this study, that’s a concern.”…….
The NTP first decided to investigate the carcinogenicity of cellphone radiation in 2001, partly in response to epidemiological studies showing a correlation between gliomas and cellphone use. Some of the studies even showed that the cancers were ipsilateral—meaning they tended to appear on the same side of the head where users held their phones. But other epidemiological studies haven’t found links between cancer and cellphones…….
Only the test results for rats have been released so far. Female rats didn’t experience significantly higher than normal cancer rates. However, among male rats that received the highest radiation exposures, 2 percent to 3 percent contracted gliomas and 6 percent to 7 percent percent developed schwannoma tumors in their hearts, depending on the type of radiation used. None of the male rats in the control groups developed those cancers……..
The authors of the NTP study did not say how their results might translate into cancer risk for humans. But “given the extremely large number of people who use wireless communication devices,” they wrote, “even a very small increase in the incidence of disease resulting from exposure to RFR resulting from those devices could have broad implications for public health.”……http://www.motherjones.com/environment/2016/05/federal-study-links-cell-phone-radiation-cancer
