Prof. James Giordano, PhD, Vice President for Academic Programs and Director of the Center for Neurotechnology Studies at the Potomac Institute for Policy Studies, is a neuroscientist and neuroethicist. He says a World Health Organization panel's findings that cell phone use may be associated with a higher risk of brain cancer certainly merit attention, although more research is needed to determine the reasons for this correlation. He also says that certain groups of cell phone users, such as children, may be more vulnerable to any possible health hazards than are other users.  Click below to watch Prof. Giordano's video comments on cell phone risks.
