Time to dismiss cell phone-cancer link?

COPENHAGEN, Denmark, April 11 (UPI) -- Two recent studies, including one from Danish scientists released Monday, have found no association between cell phone use and brain tumors.

That is the same conclusion reached by the majority of studies that have looked at the issue. Major public health organizations, such as the World Health Organization, have concluded there is no evidence to suggest an increased risk of cancer from cell phones.

So can the book finally be closed on the issue? Almost, but not quite, says Dr. Christoffer Johansen of the Danish Cancer Society in Copenhagen, Denmark, who led the study released Monday that appears in the April 12 issue of the journal Neurology.

"We cannot rule it out entirely, but we are close," Johansen told UPI.

Stephen Lonn of the Karolinska Institute in Stockholm published a study last month in the American Journal of Epidemiology that found no increased risk in brain tumors among people using a cell phone for 10 years or longer.

But Lonn said long-term users need to be more thoroughly studied. "We need more research for long-term use and research among children before we could make any conclusions," he told UPI.
