It may be too early to say for sure. The latency period or time between exposure and recognition of a tumor is around 20 years, sometimes longer. And, cell phone use in the U.S. has been popular for only  around 15 years. Back in 1996, there were 34 million cell phone users. Today there are 9-10 times as many. Keeping that in mind, it is worth taking a more detailed look at the results of Interphone, a multinational study designed to try to  answer this question. The headline from this study was there was little or no evidence to show an association between cell phones and cancer. Though, if you went to the appendix of the study, which interestingly was available only online, you found something unsettling. The data showed people who used a cell phone 10 years or more doubled the risk of developing a glioma, a type of brain tumor. And, across the board – most of the studies that have shown an increased risk are from Scandinavia, a place where cell phones have been popular since the early 1990s. For these reasons, the whole issue of latency could become increasingly important.

Ronald Herberman, director of the University of Pittsburgh Cancer Institute,  sent a memo warning staffers to limit their cell phone use. One of the possible consequences, he says, is  an increased risk of brain cancer. The city of San Francisco is trying to pass an ordinance requiring radiation warning labels on all cell phones.  The European Environmental Agency has said cell phones could be as big a public health risk as smoking, asbestos and leaded gasoline
