average length of mobile phone exposure in this
study was less than three years.
When 20 types of glioma were considered
separately, however, an association was found
between mobile phone use and one rare type of
glioma, neuroepithelliomatous tumors. It is
possible with multiple comparisons of the same
sample that this association occurred by chance.
Moreover, the risk did not increase with how often
the mobile phone was used, or the length of the
calls. In fact, the risk actually decreased with
cumulative hours of mobile phone use. Most
cancer causing agents increase risk with increased
exposure. An ongoing study of brain cancers by
the National Cancer Institute is expected to bear
on the accuracy and repeatability of these results.
2.Researchers conducted a large battery of
laboratory tests to assess the effects of exposure to
mobile phone RF on genetic material. These
included tests for several kinds of abnormalities,
including mutations, chromosomal aberrations,
DNA strand breaks, and structural changes in the
genetic material of blood cells called lymphocytes.
None of the tests showed any effect of the RF
except for the micronucleus assay, which detects
structural effects on the genetic material. The cells
in this assay showed changes after exposure to
simulated cell phone radiation, but only after 24
hours of exposure. It is possible that exposing the
test cells to radiation for this long resulted in
heating. Since this assay is known to be sensitive to
heating, heat alone could have caused the
abnormalities to occur. The data already in the
literature on the response of the micronucleus
