Serious limitations have been pointed out in nearly all the
studies of power lines and cancer.11,12 These limitations
include unblinded assessment of exposure, difficulty in
making direct measurements of the constantly varying
electromagnetic fields, inconsistencies between the measured
levels and the estimates of exposure based on wiring
configurations, recall bias with respect to exposure, post
hoc definitions of exposure categories, and huge numbers of
comparisons with selective emphasis on those that were
positive.
Both study participation and residential wire-code
categories may be confounded by socioeconomic factors. Often
the number of cases of ALL in the high-exposure categories
has been very small, and controls may not have been truly
comparable. Moreover, all these epidemiologic studies have
been conducted in pursuit of a cause of cancer for which
there is no plausible biologic basis. There is no convincing
evidence that exposure to electromagnetic fields causes
cancer in animals,6 and electromagnetic fields have no
reproducible biologic effects at all, except at strengths
that are far beyond those ever found in people's homes.
In recent years, several commissions and expert panels have
concluded that there is no convincing evidence that
high-voltage power lines are a health hazard or a cause of
cancer.6,13 And the weight of the better epidemiologic
studies, including that by Linet et al., now supports the
same conclusion. It is sad that hundreds of millions of
dollars have gone into studies that never had much promise
of finding a way to prevent the tragedy of cancer in
children. The many inconclusive and inconsistent studies
have generated worry and fear and have given peace of mind
to no one.
The 18 years of research have produced considerable
paranoia, but little insight and no prevention. It is time
to stop wasting our research resources. We should redirect
them to research that will be able to discover the true
biologic causes of the leukemic clones that threaten the
lives of children.
