Evidence still fuzzy on cell phones, cancer

(CNN) -- In the year since a U.S. cancer researcher's warning drew wide attention, more evidence is emerging that long-term cell phone use is associated with cancer, but there's still not a definitive explanation or proof of cause and effect.

Last summer, Dr. Ronald Herberman, then director of the University of Pittsburgh Cancer Institute, issued a warning to about 3,000 faculty and staff, listing steps to avoid harmful electromagnetic radiation from cell phones. This included keeping the phone away from the body as much as possible and not allowing children to use cell phones except in emergencies.

"Since I put out that precautionary advisory in July of last year, I believe there is more indication for concern, particularly among children," he recently said.

I wonder whether the risk is mitigated by using either Blue Tooth headset or a hard wire ear piece.
