"While experimental evidence and very limited human studies suggest that we should be cautious, people should realize there are many things we are exposed to every day that also is classified by IARC as possibly carcinogenic," Dr. Peter Shields, chief of Georgetown University Hospital's cancer genetics and epidemiology program in Washington, D.C., told ABC News in May. "The classification used by IARC for cellphones is the lowest of all the carcinogenic classes, and no one should think that cellphones pose the same risk as smoking and asbestos."
Doctors appear to be split on the possibility of risks when it comes to their own cellphone habits. After the International Agency for Research on Cancer announcement in May, ABC News reached out to 92 physicians. Sixty-five of these doctors said they would continue to hold their cellphones up to their ear, but 27 said they would use hands-free devices to minimize their risk.
