Studies still looking for link between cell phones and brain tumors

City workers make phone calls outside the London Stock Exchange in Paternoster Square in the City of LondonBy Kathryn Doyle NEW YORK (Reuters Health) – The heaviest users of cell phones may be at higher than average risk of being diagnosed with a brain tumor, according to a recent French study. This isn’t the first study to point to a tumor risk with heavy cell phone use, said Dr. L. Dade Lunsford, a distinguished professor of neurosurgery specializing in brain tumor management at the University of Pittsburgh. But these kinds of studies rely on people to recall how much they have used cell phones in the past with no indication of their actual use, said Lunsford, who was not involved in the French research. The new results found no difference between regular cell users and non-users, which suggests that if there is a link, it is only applicable for people who claim to use their cell phone the most, he noted by email.
