Just when we thought we had this whole cellphones do / don't cause cancer bit was behind us, here comes another study to say that they in fact do. The study, which was put together by Finland's Radiation and Nuclear Safety Authority, suggests that people who used cellphones longer than 10 years were 40 percent more likely to develop gliomas (a nervous system tumor) on the side of the head where the cellphone's radiation would enter the head. While we are aware of several studies that go either way on the matter, Microwave News' editor Louis Slesin thinks it is "compelling evidence" because, "We now have two tumor types found among people who use mobiles for more than 10 years shown by two different research groups." Of course, a rebuttal from the Mobile Operators Association said otherwise: "The findings related to tumor location are difficult to interpret." It's hard to really form an opinion considering the amount of data that consistently contradicts itself, but you can decide for yourself when the findings are published in International Journal of Cancer later this year. For now, we will have faith in our mobiles and pray that later on down the line we're not on the wrong end of the impending "I told you so."
