When findings from the
largest study of the
possible link between
cell phone use and brain cancer
were released in May, media reports
on its conclusions varied
widely. “Heavy Mobile Users
Risk Cancer,” read one headline.
“No Proof of Mobile Cancer
Risk,” proclaimed another.
Which, if either, was true? It’s
no small question, considering
that 91% of Americans have cell
phones, and the number of users
worldwide will reach 5 billion
this year.
