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 Radio Frequency (RF) energy 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 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.
