Cell Phones Don't Increase Chances of Brain Cancer
mclearn sends in news of "a very large, 30-year study of just about everyone in Scandinavia" that shows no link between mobile phone use and brain tumors. "Even though mobile telephone use soared in the 1990s and afterward, brain tumors did not become any more common during this time, the researchers reported in the Journal of the National Cancer Institute. Some activist groups and a few researchers have raised concerns about a link between mobile phones and several kinds of cancer, including brain tumors, although years of research have failed to establish a connection. ... 'From 1974 to 2003, the incidence rate of glioma (a type of brain tumor) increased by 0.5 per cent per year among men and by 0.2 per cent per year among women,' they wrote. Overall, there was no significant pattern."
Glioma != "brain tumors". There are many other forms of brain tumors which this study does not cover. The story should be "No link between glioma and cell phone usage found."
Are there any levels/frequencies of RF that are known to increase cancer rates?
No, radio waves are non-ionizing.
Or could I live on top of a radio tower and do just fine?
You might get cooked as in a microwave, but no cancer.
Give me Classic Slashdot or give me death!
I'll save you the trouble of trying to rationalize 1 and 2. Just pick 3.
I'm William of Ockham, and I approve of this message.

Cooking = damage. And the damage can increase the odds of cancer.

Quote: "Esophageal cancer numbers rose in regions where people preferred their tea very hot, and dropped where tea was served at a cooler temperature. "
"But unlike booze and cigarettes, Malekzadeh said evidence in his study showed it's not the chemicals in the tea that matters. "
In WWII,
[apocryphal stories were told of]
many shipboard radar operators were permanently sterilized by RF leakage. Don't think of it as radio waves, think of it as radiation.
No!
Think of it as heat.
The tissue burn is almost the same.
No, it's not. Radiation damages you even though you don't feel it and it doesn't burn. Microwaves heat things up, but are not ionizing. In terms of damage, they are a heat source-- they can damage because they heat you up, but they most particularly do not damage the way radiation does.
(by the way, people in the US usually think of the word "radiation" as meaning "ionizing radiation", which microwaves aren't. I'm assuming you meant it this way.)
