development used
animals that had been
genetically engineered
or treated with cancer-
causing chemicals so
as to be pre-disposed
to develop cancer in the
absence of RF exposure.
Other studies exposed
the animals to RF for
up to 22 hours per day.
These conditions are not
similar to the conditions
under which people
use wireless phones,
so we do not know with
certainty what the results
of such studies mean
for human health. Three
large epidemiology stud-
ies have been published
since December 2000.
Between them, the
studies investigated any
possible association
between the use of wire-
less phones and primary
brain cancer, glioma,
meningioma, or acoustic
neuroma, tumors of
the brain or salivary
gland, leukemia, or other
cancers. None of the
studies demonstrated
the existence of any
harmful health effects
from wireless phone RF
exposures. However,
none of the studies can
answer questions about
long-term exposures,
since the average period
of phone use in these
studies was around three
years.
