The cancer - cell phone connection will never be established or proven, for the same reasons that cancer - abortion connection will never be established proven. We need it therefore we will do everything to deny it. I don't know for certain that there is a connection, I don't know if anyone knows. But I know how this country likes to operate, what we like to admit and what we like to deny. We make things that make us too uncomfortable just not exist. (To be fair, all societies operate this way.)
