http://www.medpagetoday.com/PublicHealthPolicy/PublicHealth/26776 A work group of the World Health Organization has declared the radiofrequency electromagnetic fields emitted by cell phones to be "possibly carcinogenic to humans."
The declaration was made after a week-long meeting of the International Agency for Research on Cancer (IARC) in Lyon, France, which involved 31 scientists from 14 countries, who decided there was enough evidence linking use of cellphones to an increased risk of glioblastoma.
The declaration puts these energy fields into the IARC's group 2B for carcinogenic agents -- one notch above compounds "not classifiable" as cancer-causing because of inadequate evidence.
Other agents in group 2B include progestins and anti-epileptics such as phenytoin and phenobarbital.
Jonathan Samet, MD, of the University of Southern California and chair of the work group, said the "evidence, while still accumulating, is strong enough to support a conclusion and the 2B classification."
