Who’s Afraid of Mobile Phone Cancer By Brian Simpson

     Animal models in drug and vaccine testing are used to confirm drug effectiveness, but not conclusively until human studies are done. But, if bad effects are seen, then this is grounds for caution. Not so, apparently, for mobile phones. I am sure that most young people, who are virtually a part of their mobile phones, are more concerned about their phone getting cancer than them. Nevertheless, a recent study found that there was “clear evidence” of malignant tumours in the hearts, brains and adrenal glands of male rats.

     One science site says that human users should not be unduly concerned:

“The rodents were exposed to cellphone radiation — known as radio-frequency radiation — at greater levels, and for much longer periods, than what people experience, the researchers said. "The exposures used in the studies cannot be compared directly to the exposure that humans experience when using a cellphone," John Bucher, a senior scientist with the U.S. National Toxicology Program (NTP) and co-author of the study, said in a statement. Bucher added that the mice were also exposed to radiation across their whole bodies, which is not what happens in people, who instead receive only local exposure to the specific area where they hold the phone.

Still, the researchers said their findings question the long-held assumption that the radio-frequency radiation used by cellphones poses no health.”

     This study cost $ 30 million and took 10 years to complete, and at the end of the day, well, it is inconclusive. No doubt, any study would be found to be problematic by the establishment, for can one really think that any profitable bit of technology could be rejected because it harmed people? No, commerce must always come first.
