Mobile Phone Industry Fights to Keep You Ignorant of the Risks. I am not normally a person who posts scare stories about this cancer risk or that one. However, there is now enough scientific evidence that cell phone radiation, in enough quantity, can cause cancer, that we all need to figure out how we use cell phones. With the widespread availability of bluetooth connections for use, it is obvious to me that it is foolhardy to talk on your phone by placing it next to your ear. There is clearly risk here. Of course, there are many environmental risks that we face every day that are unavoidable. It is part of living in a modern society. We are certainly living longer because of technology, and there are certainly risks worth taking. However, let's be smart about this stuff. At least we can try to minimize the risk. Rule Number 1 for me? Get that phone away from your head.
