David Savitz(CNN) The city of Berkeley, California, passed a law that goes into effect next month requiring cell phone stores to inform customers about safety recommendations. The move reopened a decades-old debate about whether mobile phones cause brain tumors.
"There are individual studies and findings that do produce a risk, but on balance the judgment has to be made on the totality (of the evidence)," Savitz said, adding that there is error in even the best and biggest studies.
"We know quite a bit (about the risk) actually and it seems extremely unlikely that there is an effect. We are down to the range that there is no risk or a risk that is almost too small to detect," Savitz said.
