Cell Phone Cancer Probably Just Another Hype

Cell phone-iphile

Cell phones are in the news, as the latest scientific-related worry causer. Our media thrives on such scary stories, whether or not they are factually true or not. I wouldn’t throw out your cellphone just yet…

Basically, the WHO put cell phones into the Group 2B category, meaning they are “possibly carcinogenic to humans”. Aiiiieee! Sounds scary… except that word “possibly”, it turns out, needs to be understood a little more quantitatively.

I poked around some news sites (like CNN and MSNBC), and while they aren’t over-hyping it, in my opinion they aren’t being entirely fair, either. The claims I’ve seen from people linking cell phones to brain cancer make it seem as if the connection is obvious, but the results from the WHO make it clear that’s not the case. There might be a connection, but if there is it’s not terribly clear. I’ll note the studies only appear to cover a time base of ten years; it’s not possible to know what happens after, say 15 or 20 years. Even then, other environmental factors dominate such studies, making teasing out a weak signal very difficult.

You may also wish to note what other things are categorized as Group 2B possible carcinogens, including gasoline, pickled vegetables, and (GASP!) coffee. My opinion here is that while a link between cell phones and brain cancer cannot be ruled out, without a strong correlation and a numerical statement about the odds, it seems very unlikely to me that such a connection is something to worry about. I’m far more worried about the dingus in traffic in front of me gabbing to his friend on his phone and causing an accident than I am about me getting brain cancer from my own.
