I recently wrote a post about the lack of any evidence that cell phones cause cancer. Not too surprisingly, a lot of alarmist comments followed, many of which actually proved one of my points that the threat is exaggerated: at the very best studies show a very tenuous link between cell phones and health issues, yet people are claiming the relationship is obvious. Clearly, that's not the case.
I'll admit my title, "Repeat after me: cell phones don't cause brain cancer", was overzealous. It's very difficult to prove that with 100% accuracy. As a skeptic I have to admit that there is some slim chance of a causational relationship, even though study after study show there isn't.
So it was interesting to me to see Michael Shermer write a post about this for the Skepticblog: Cell phones and cancer. It's a well-written and clear article with references, links, and quotations from doctors showing that, despite the claims by many people, there is very little or no reason to think cell phone radiation causes brain damage.
Of course, if you're using one to text while driving, brain damage is far more likely in the form of sudden catastrophic deceleration. So that's a good time to avoid cell phones. But in ordinary use, I'm not worried, and I'll continue to use mine. Especially if I finally do start playing Angry Birds.
