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.
