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 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 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 phones 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.
