Researchers have found that no matter which way they punched the numbers, having a cell phone tower nearby while pregnant doesn’t appear to increase the number of childhood cancers. The team from Imperial College in London tracked down all cases of childhood cancer in Britain from 1999 to 2001. They matched 1,397 of the sick children with healthy children of the same age, gender and demographics. The ones whose mothers lived near the towers were no more likely to have been sick. In fact, in the case of brain cancer, living near a cell phone tower was correlated with a reduced risk.
