Safety Guidelines 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 predisposed 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 around three years. 5. What research is needed to decide whether RF exposure from wireless phones poses a health risk? A combination of laboratory studies and epidemiological studies of people actually using wireless phones would provide some of the data that are needed. Lifetime animal exposure studies could be completed in a few years. However, very large numbers of animals would be needed to provide reliable proof of a cancer promoting effect if one exists. Epidemiological studies can provide data that is directly applicable to human populations, but 10 or more years followup may be needed to provide answers about some health effects, such as cancer. This is because the interval between the time of exposure to a cancer-causing agent and the time tumors develop - if they do- may be many, many years. The interpretation of epidemiological studies is hampered by difficulties in measuring actual RF exposure during day-to-day use of wireless phones. Many factors affect this measurement, such as the angle at which the phone is held, or which model of phone is used. 106

disposed to develop cancer in the absence

What research is needed to decide
whether RF exposure from wireless
phones poses a health risk?
A combination of laboratory studies
and epidemiological studies of people
actually using wireless phones would
provide some of the data that are needed.
Lifetime animal exposure studies could
be completed in a few years. However,
very large numbers of animals would
be needed to provide reliable proof of
a cancer promoting effect if one exists.
Epidemiological studies can provide
data that is directly applicable to human
populations, but 10 or more years follow-
up may be needed to provide answers
about some health effects, such as cancer.
This is because the interval between the
time of exposure to a cancer-causing
agent and the time tumors develop - if
they do- may be many, many years. The
interpretation of epidemiological studies
is hampered by difficulties in measuring
actual RF exposure during day-to-day use
of wireless phones. Many factors affect
this measurement, such as the angle at
which the phone is held, or which model of
phone is used.
