I don't see what the RF debate has got to do with this?
Unless the RF causes heating there is no scientific edvidence to indicate that it can cause tissue damage. The only thing that makes RF any more dangerous than infrared radiation is that it's more penetrating and rases the temperature of the internal organs and not just the skin.
To cause cancer the DNA of cells has to become corrupted, there are two main ways of doing this: chemicals can react with the DNA and corrupt it or ionising radiation can knock out electrons in the DNA causing reactions which damage the DNA. RF radiation is too lower energy to cause any chemical reactions, therefore is chemically inert.
The only way RF can damage cells is by heating them, most of the body can withstand fairly large changes in temperature and a large amount of RF energy would need to be absorbed to cause any damage. The only sensiitive areas of the body are the brain an genitals which are more easilly affected by small changes in temperature.
I think the problem is that most people don't understand the effects of RF radiation on the body and they fear the unkonwn.
EDIT:
I think I can see your point you're talking about safety.
Well there is evidence that repeated electric shocks can damage nerve cells but I can't find it on Wikipedia even though I've read it before.
