More muddy water on cell phone use, kids' brain cancer risk – The ...

A new study touts findings that kids who use cell phones are at no greater risk of brain cancer than non-users. But before you heave a sigh of relief and allow your kids unrestricted cell phone use, take a harder look at what the study, published in the Journal of the National Cancer Institute, does and does not reveal. Using data from a multi-center study - called CEFALO - of children and teens who have brain tumors, the study by Swiss researchers concludes that "regular users of mobile phones were not statistically significantly more likely to have been diagnosed with brain tumors compared to <a href="http://www.mybape.com/bape2009shoes-c-1.html"><strong>bape apes shoes</strong></a> nonusers." The study also concludes that kids who started to use mobile phones at least five years ago were not at higher risk for brain cancer compared with kids who had never regularly used mobile phones. This study surveyed 352 kids with brain tumors between 2004 and 2008, who the researchers concluded were "regular cell phone users." The kids lived in Denmark, Sweden, Norway and Switzerland. The catch? The researchers' definition of a "regular user" was one mobile phone call a week for at least six months. The researchers did not look at exposure time using call duration. Defining a "regular cell phone user" as once a week for at least six months is very low. According to a Pew Research Center study released in 2010, U.S. "teens typically make or receive five calls a day. White teens typically make or receive four calls a day, or around 120 calls a month, while black teens exchange seven calls a day or about 210 calls a month and Hispanic teens typically make and receive five calls a day or about 150 calls a month." So they didn't find an increase between the "regular user" <a href="http://www.mybape.com/bapecartoonshoes-c-9.html"><strong>kids bape shoes</strong></a> group and the control group. But based on their definition of a regular user, it’s unlikely that they would. Also because, as noted by the National Cancer Institute, "The interval between exposure to a carcinogen and the clinical onset of a tumor may be many years or decades.” That means if a 13-year-old starts using a cell phone on <a href="http://www.mybape.com/bapeclassicshoes-c-11.html"><strong>discount bape</strong></a> a daily basis in 2011, it will be years or decades before any damaging evidence is seen. Very few people believe talking on the phone once a week for six months will cause brain cancer. But for teens who are using their cell phones in a more typical fashion – at least five times per day- the answer is less clear. “This new JNCI report represents an astonishing, disturbing and unwarranted conclusion,” according to Devra Davis, president of Environmental Health Trust, who also served as an adviser to the U.S. Department of Health and Human Services. She adds “interestingly, the researchers advocate, as we do, taking simple precautions including the use of a headset and speakerphone. But to conclude—as an editorial written by industry-associated scientists accompanying the article does—that that children face no risks from cell phones, does <a href="http://##############.thelambda.sk/displayimage.php?pos=-26"><strong>GHD IV Styler set you will find the legendary ghd IV styler ...</strong></a> a profound disservice to the public.” At the end of the study, the authors point out the study’s limitations. Interestingly, the authors note, "There might also be an inherent limitation regarding the level of exposure in our study." The researchers acknowledge that cell phone use is common in adolescents and that the common rate of use has increased since the study period. The study authors say that since mobile phone usage among children and adolescents has increased over the years, they encourage a careful watch of the trend in the years ahead. They concede that additional retrospective studies based on memory (like their study) will not add clarification to the issue.
