Though the results of their $24M cellphone cancer study were inconclusive, the World Health Organization has added cellphones to their "carcinogenic hazard" list today. Also on the list: lead, chloroform, and engine exhaust.

Here's how one neurologist explains the hypothetical effect of cellphone radiation:

What microwave radiation does in most simplistic terms is similar to what happens to food in microwaves, essentially cooking the brain. So in addition to leading to a development of cancer and tumors, there could be a whole host of other effects like cognitive memory function, since the memory temporal lobes are where we hold our cell phones.
