The World Health Organization has made a more or less official decision that cell phones might possibly cause cancer even though researchers have tried for years to prove it without success.
The story has gotten huge coverage worldwide because 5 billion people carry cell phones and it might possibly matter to them.
But let me tell you the story in my own way and then you can evaluate the risk for yourself.
The World Health Organization has a specific list of categories for pigeonholing carcinogens, noncarcinogens, and possible carcinogens.
It has pigeonholed cell phones being held against your ear as a possible carcinogen because one study shows a possible link with glioma, a kind of cancer in your head that is not very common.
The determination has clearly been made with an abundance of caution because numerous other studies, including at least one that tracked tens of thousands of people, found no brain cancer link.
When you read the different categories you'll see the WHO researchers more or less had to put cell phones on this particular list, not because of any fresh concern but for bureaucratic reasons - no other list fits.
The most telling thing about research on cell phone use is this: researchers all over the world are trying to find a link between cell phones and cancer and if there is one it should be obvious by now since cell phone use has exploded worldwide and we've had hundreds of millions of people using cell phones a lot for years.
The response to that by people who are convinced there is a link anyhow is that it must show itself slowly and we'll see an epidemic of brain tumors in 10 or 20 years.
I follow pretty closely any research into health problems tied to electricity, partly because I've spent a lifetime working in broadcasting and years working in close proximity to radio transmitters.
From 1972 to 1975 I worked at a desk that was in the transmitter room - I could lean back and rest my head on the glass window of the transmitter, and the tower was just outside, a couple hundred yards from the building. I always wondered if that caused the pea-shaped bump on the back of my scalp, which I had removed a few years ago (benign, thanks for asking) and which has not grown back.
My mother died of a brain tumor, the existence of which was unknown to us until it began causing facial twitches and stroke symptoms. She died three months to the day after the doctors gave her three months. This is not an impersonal matter for me.
I also know that data can be fiddled. Studies of the health effects of high-tension power lines managed to play down any possible effects by calculating data in a circle around a power source, when any electrician can tell you the effects, if any, would probably be confined to a more narrow area where the polarity was just right.
But apart from a statistically suspicious incidence of childhood leukemia really close to power lines, researchers spent years, decades even, trying to find a connection between power lines and serious disease without ever quite nailing it.
So even though humans are notorious for playing down the risks of anything they deal with on a daily basis, I've got to tell you that I'm starting to wonder if the electrical industry is right in saying cell phones are, because of the very low amounts of current involved, safe to use.
Eric Barnouw, in his three-volume history of U.S. broadcasting "A Tower in Babel," wrote that when radio was new a farmer wrote to complain that one of his cows died and he thought some radio waves had struck it. The farmer wrote the letter in the 1920s. I read the book in the 1970s. I wonder if, a couple decades hence, we'll laugh at our worries about wireless devices, or the studies that told us now that we're too serious.
For now, I feel safe in saying the greatest risk of cell phones is that you'll be t-boned running a red light while distracted by a cell phone call.
