For years, we've heard of a possible link between cell phone use and cancer. The evidence is clear: cell phones do cause brain cancer," said Dr. Devras Davis, president, Environmental Health Trust. Dr. Davis says the young brain absorbs twice as much radiation as an adult. Doctors and scientists from across the country took on the issue during a pediatric conference [in] Baltimore. Panelists also found a connection between exposure to cell phone radiation and other health issues. "There's a correlation between cell phone use in pregnancy and behavioral problems in their children," said Dr. Hugh Taylor, Yale School of Medicine. "These devices are ... straining our family relationships because the average mom or dad will check their phones 60 to 110 times a day," said Dr. Catherine Steiner-Adair, clinical psychologist. The infant brain - even while in the womb - is especially vulnerable. Holding your phone even a few inches away can lower the risk. They recommend using headsets, and when you're not on your phone, to keep it as far away from you as possible. "So we're getting like a triple, quadruple whammy between the biological effect, the psychological effects and the brain waves effects," said Dr. Martha Herbert, pediatric neurologist. Effects may not be completely avoidable in a high-tech world. Some researchers say the U.S. is lagging behind other countries when it comes to radiation research and prevention.
