Will cancer warning lead to cell decay?

In a Post Gazette story today, the director of the University of Pittsburgh Cancer Institute and UPMC Cancer Centers is saying cell phones pose a risk to our health.
Dr. Ronald Herberman "believes he is the first U.S. cancer center director to approve the release of such an advisory," according to Joe Fahy's story.
Despite other countries limiting exposure, many in the US, including the American Cancer Society, say cell-phone use hasn't been proven to cause brain cancer, according to the story.
Do warnings like this make you rethink your cell phone usage? Or do you think this is a lot of bunk?
I'm, frankly, a little worried about this. We're bombarding our bodies with so much stuff.
Doesn't sound like a green issue? It is.
A lot of green choices are about our health. We choose organic because we believe it is healthier; we recycle because we don't believe turning our countries into a giant landfill is good for us; and we try to reduce pollution because we know our lungs aren't set up to filter out so many poisons. A lot of eco-friendly choices are actually people-friendly choices. The earth is the only habitat we have. It makes sense that things that are good for the earth are good for us.
This might be one of those things. Cell phones could be linked to brain tumors. Some people also worry about what effect cell towers and "beamed" conversations have one our bodies. (I know they aren't "beamed" per se, but this is an eco message, not a science lesson.) Maybe cutting back would be a good idea.
Herberman suggests limiting conversations, using the hands-free option and keeping kids from using cell phones. (Like lead paint, a little goes a long way in a kid's body, Herberman is saying.)
I have a cell phone, but I only have 300 minutes a month, a small package by today's standards, and I rarely use all 300. I'm going to strive to lower that number or to use the hands-free option when possible.
Let's say it doesn't cause cancer. I'll still be less likely to become that idiot driver that is oblivious to the world because of her cell phone. You're welcome. *grin*
