Maybe. Probably not. Scientists still aren’t completely sure if cell phones cause brain cancer.
It’s fairly accepted that cell phones don’t cause cancer with short-term use, but since cell phones haven’t been around long enough to be considered “long term,” it’s too early to say for sure.
That said, major studies in recent years indicate that regular cell phone use (at least sixty minutes a day for four or five years) does not lead to a higher incidence of brain cancer, nor is there a higher incidence of cancer along the side of the head where the phone is used the most.
So far, the biggest danger of cell phones seems to be when users insist on driving while using them (see below).
That, and the violence that threatens to flare up when users yak on their cell phones in theaters, meetings, and restaurants.
