    So stop worrying about all the things that contribute so little to the risk that a 350,000 person study can't identify a link. Enjoy your life, and avoid the things with a strong correlation to cancer, like tobacco, excessive UV exposure, high levels of radioactivity, etc.

    • The supposed cancer risk with cell phones is that a microwave radiation source close to your skin will increase the temperature in some cells which increases the cancer risk. However, this temperature increase is very localized and only temporary. If there is a risk, it will be way below 10^ -5 and hard to quantify, since it is somehow a problem to find people that don't expose themselves to other cancer risks, like walking in the sun, eating a byte of junk food, or not getting enough sleep or being stresse

Also, the transmit power of cell phones it 0.6W or less (usually much less except when you're at the fringe of reception). The power and frequencies are so small that they will probably never be able to establish a correlation, even if there is some small risk. The studies that have been done are sufficient to eliminate it as a real concern, even though we'll never be able to pro

        • The microwave frequency that heats water is 2.45GHz,

          No, it's not. That frequency is used for microwave ovens because it is the Industrial, Scientific and Medical (ISM) band, and hence you don't need a FCC license every time you turn your microwave on.

          Water heating isn't terribly sensitive about what frequency. It's not a resonance-- it would heat equally well at 2.25 or 2.55 GHz. The oscillating electric field adds energy to the water molecule dipoles.

          • Thanks for that correction. I had missed that.

            Still, the power levels are so low, maximum is 1% of a modern microwave oven, and radiated in all directions so that amount actually reaching human tissue doesn't produce enough heat to even feel it, certainly not enough that blood circulation can't remove any excess heat. Therefore, damage from heating is extremely unlikely. And since it's non-ionizing, there is no other known mechanism by which it can cause harm (cancer or other).
