How Might Cell Phone Signals Cause Cancer?

An expert answers questions about what could happen at the cellular level after a report links radiofrequency signals to tumors in rats. The release of a study Friday linking cancer in rats to the type of radiation emitted by cell phones presents some of the strongest implications in more than two decades of research that higher doses of such signals could be linked to tumors in laboratory animals—unsettling news for billions of mobile phone users worldwide. Still missing, however, is a clear understanding of exactly how radiofrequency (RF) radiation used by mobile phones might create cellular-level changes that could lead to cancer.
