4. What are the results of the
research done already?
The research done thus far has
produced conflicting results,
and many studies have suffered
from flaws in their research
methods. Animal experiments
investigating the effects of
radiofrequency energy (RF)
exposures characteristic of
wireless phones have yielded
conflicting results that often
cannot be repeated in other
laboratories. A few animal
studies, however, have
suggested that low levels
of RF could accelerate the
development of cancer in
laboratory animals. However,
many of the studies that showed
increased tumor 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 don't 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
