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 studies have
been published since December 2000.
Between them, the studies investigated
any possible association between the
use of wireless 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.
