After looking at some of the commentary and news, I come away with an ambiguous conclusion. There seems to not be enough data yet, but if a teenage cell phone user was tracked from age 13 to 65, that may pose some solid data for this conversation. Some points worth noting:
Incidence of the most common type of brain cancer in the U.S. has dropped 0.4 percent per year between 1987 and 2007. This would be about the very same period that we all started using cell phones. That doesn’t necessarily mean the drop wouldn’t have been steeper had we not used cell phones. And it doesn’t necessarily mean cell phones don’t have a long-term effect that we may see in years to come. It does mean that brain cancer incidence has plummeted just as cell phone use has taken off.
