After going to great lengths on their website to remove any fear anyone has over cell phone safety here's the quote that follows which sums up the position of the FDA on this issue: "There is no proof, however, that wireless phones are absolutely safe."
How's that for a vote of confidence? Does that make you want to run out and extend your cell phone contract?
Wouldn't we want to establish proof of safety first, before something is placed on the market? We don't do this with pharmaceuticals or food or anything else. Why are cell phones exempt from proof of safety? Any medical professional will tell you tumors take 10, 15 even 20 years to develop. Cell phones have been on the market since 1983. However, only in the last 5-7 years has this market really exploded. Today's cell phone is a different technology than back in 1983, too. So we won't know for another five, 10 or 15 years if we're all participating in somebody's giant experiment or not.
In the meantime, use your cell phone safely and minimally.
