The National Toxicology Program (NTP) animal study started in 1999 released summary of their findings this week. Cell Phones cause brain cancer. 50 Hz, the power line frequency used in Europe, causes heart tumors.
The cell phone "radiofrequency radiation (RFR)" study is led by the NTP, headquartered at the National Institute of Environmental Health Sciences. The NTP has posted their report of the study’s findings: Report of Partial findings from the National Toxicology Program Carcinogenesis Studies of Cell Phone Radiofrequency Radiation in Hsd: Sprague Dawley® SD rats (Whole Body Exposure). Note the comments about the study. Some are insightful for future studies most are just the usual fear mongering.
Length report http://microwavenews.com/news-center/ntp-cancer-results that can be summed up this way:
"Importantly, the exposed rats were found to have higher rates of two types of cancers: glioma, a tumor of the glial cells in the brain, and malignant schwannoma of the heart, a very rare tumor. None of the unexposed control rats developed either type of tumor."

Cell Phone Convenience or 21st Century Plague?
Compiled by Dr. Nick Begich and the late James Roderick.
If you are at all interested in this stuff a book you MUST read is The Body Electric by the late Dr Robert Becker (Not Bob Beck).
There also lots of scam devices out there that sell you something to reduce cell phone radiation then show before and after thermal graphs. I want to see a thermal graphs of an empty cell phone case held to the head. I expect it will give the same thermal graph.
If such a device worked there will be a noticeable decrees in battery life. If the 'radiation' is reduced the cell tower would get a weaker signal and the range would be less. The transmit power level of a cell phone is controlled dynamically which is why when it places with poor cell phone reception the battery drains faster due to the phone using a higher transmit power. If such a device worked it will drain the battery faster even with no connection to the battery.
A simple way to reduce exposure is use wired ear buds. They still don't bring the risk to zero. Bluetooth Handsfree headsets are not improvement. Bluetooh operates at 2.6 GHz. The same frequency as your microwave oven and WiFi. I'm not putting a tiny microwave oven next to my head...
