content: There is, but the problem is that the increase has been happening for over 100 years, now. With a continuous increase, which started before cell phones, it's hard to tell if the increased use of mobile technology is contributing to the (recent) increased numbers of cancer incidents, or not. This (recent) increase could be the natural increase that was happening before phones, or it could be accelerated due to ubiquitous technology.  This is a big devisive factor, and the point at which this study dropped the ball. The rats had a natural cancer rate, but even that didn't present itself in the control group. So the metasticized glial cells in the Testing group can't be defined as a result of the radio frequencies, or not.  The only thing you can lók at and wonder about, experimentally, is about the male-vs-female testing groups... But that doesn't even give you anything worthwhile. Apparently, some of the tested males had gliomas, which COULD have been a control issu  3000  e as we stated before (these rats have a 1-2% chance of getting it, regardless)... But it says NONE of the tested females showed any tumorous glial cells. This is interesting, but without proper research, it doesn't say much of anything.
