Cell Phones and Brain Cancer
As Dr. Gupta writes, it's too early to tell if cell phone exposure contributes to the incidence of brain cancer. It takes something like 20 years of exposure before a tumor would likely develop.
Still, not having to worry about it myself (I use my cell phone maybe one or two minutes over 3 months) I still think it would be fun to see the expression on many people's faces if science did conclude there is a direct link. I'll be there'd be a lot of you looking like you just found out you had unprotected sex with someone who has AIDS.
