Regarding cell phones, tumors, and headsets

Cell phones and Bluetooth headsets both use radio frequency to transmit data. Given that cell phone use has been linked to tumors, using a wired headset would be the absolute safest bet. However, using a Bluetooth headset is already many times safer than not using a headset at all because of the difference in transmission power.
According to Wikipedia, the maximum transmission power of GSM cell phones is 1 or 2 watts, depending on frequency. The maximum transmission power of a Bluetooth headset is 2.5 milliwatts. That’s a 400x decrease. So please, don’t think a Bluetooth headset is “no good either.”
