(NaturalNews) A report issued by the International Electromagnetic Field Collaborative and endorsed by 43 scientists from 13 countries has reviewed the evidence linking cell phone use to brain tumors, and refuting the methodology of a forthcoming industry-funded study expected to give the phones a clean bill of health."I fear we will see a tsunami of brain tumors, although it is too early to see that now since the tumors have a 30-year latency," study author Lloyd Morgan said. "I pray I'm wrong, but brace yourself."Among the research cited in the study was a recent study by a Swedish team of scientists that found a 420 percent higher risk of brain cancer among people who had started using cellular or cordless phones as teenagers. Older analog phones, which are now mostly off the market, had been found to increase cancer risk by 700 percent.Because children are especially vulnerable to radiation, the report recommends that parents not allow their children under the age of 18 to use mobile phones except in emergencies, or to sleep with cellular phones under their pillows. It recommends using corded land lines whenever possible, and using cellular phones mostly as answering machines, turning them on only to check messages and return calls. Use of cell phones inside buildings or in cars increases cancer risk, as it increases the radiation a phone must emit to function. Use of text messages and non-wireless headsets can reduce cancer risk. The report also advises against carrying cell phones against the body, even in pockets."Some countries are already banning cell phones over health concerns, with France saying children in elementary schools can only use them for texting," Morgan said.The report also sets out 11 flaws in the forthcoming Interphone study, a study on cell phones and health being prepared by the wireless industry in 13 different countries. These flaws include the exclusion of non-cellular cordless phones (which also emit radiation), children and young adults (the most vulnerable demographics) from the study, the exclusion of certain types of tumors, and the exclusion of participants who died or were too sick to answer questions.Sources for this story include: www.pcworld.com
