Epidemiology (June, 2010) compared
cell phone usage for more than 5,000
people with brain tumors (glioma and
meningioma) and a similar number of
healthy controls.
Results of this study did NOT show
that cell phones caused brain cancer.
In this study, most people had no
increased risk of brain cancer from
using cell phones. For people with the
heaviest use of cell phones (an
average of more than ½ hour per day,
every day, for over 10 years) the study
suggested a slight increase in brain
cancer. However, the authors
determined that biases and errors
prevented any conclusions being
drawn from this data. Additional
