Link Between Abortion and Breast Cancer
Reported December 23, 2005
(Ivanhoe Newswire) -- In the most recent issue of
the Journal of American Physicians and Surgeons, Joel Brind, Ph.D., of
Baruch College in New York, discusses the link between abortion and breast
The argument over whether there is a link dates back to 1996 when Brind and
colleagues conducted their first analysis of 21 studies and concluded a link
exists between induced abortion and breast cancer. The National Cancer
Institute called the results of the report inconclusive and/or inconsistent.
Seven years later the National Cancer Institute announced the findings of
their own study, which indicated no link between induced abortion and breast
cancer. This re-analysis was published in The Lancet in 2004.
Now, Brind has taken up the argument again and performed a meta-analysis of
the data from 10 studies reported between 1996 and 2005. Again, he concludes
there is a link between the two.
In his report, Brind points to reporting bias and misclassification as two
of the points that make these previous studies flawed. For example, he says
there exists a cohort effect that is the result of comparing two different
populations. According to Brind, one study only compared a younger group
that experienced most of the abortions with an older group that developed
most of the breast cancers.
Additionally, he says short time spans between the abortions and the
incidence of breast cancer make these conclusions incorrect.
"It is only reasonable to conclude, from all extant evidence, that induces
abortion is indeed a risk factor for breast cancer, despite the strong and
pervasive bias in recent literature in the direction of viewing abortion as
safe for women," Brind says.
Brind also says, "It is deplorable that in an era in which women's rights
appear so prominently on the political and public health landscape, women
should be denied the right to know about the breast cancer risk-increasing
effect of such a common matter of choice as induced abortion."
