Abortion
and breast cancer
By Ellie Lee

An article in the Mail on Sunday (13/8/00) endorsed
the claim that there may be a link between abortion and breast
cancer.
BPAS have responded to the
article as follows:
Women contemplating having
abortions may be concerned about reports that 'abortion
could lead to breast cancer'. The Mail on Sunday ran this
as a headline on its front page misreporting comments that
were given by the Royal College of Obstetricians and Gynaecologists
and BPAS. The Mail claimed that the RCOG were to advise
doctors that women should be told that abortion may increase
their risk of breast cancer. The RCOG have issued no such
advice. The advice that the Daily Mail refers to is that
already published in the evidence based guideline. The RCOG
guideline states that the evidence on breast cancer risk
is inconclusive. However, it also clearly states that when
the studies that are least susceptible to bias are examined
'the evidence suggests that induced abortion does not increase
a woman's risk of breast cancer in later life'.
A further comment on this
issue will be posted on the BPAS site shortly. The site
can be found at www.BPAS.org
The actual finding of the
RCOG Clinical Effectiveness Support Unit, published in the
RCOG Evidence-based Guideline on the Care of Women Requesting
Abortion, differs substantially from the view attributed
to the RCOG in the Mail on Sunday. As the BPAs comment notes,
it states that that available evidence on an association
between induced abortion and breast cancer is currently
inconclusive.
In addition, the Guideline
notes that the validity of the evidence gathered from studies
which compare incidence of breast cancer in women who have
and who have not had an abortion may be questionable because
of the reluctance of women studied to reveal whether they
had an abortion. Studies based on national registers are
less prone to inaccuracy because they do not rely on subject
recall. Such studies have not shown any significant association
between abortion and breast cancer. The Guideline therefore
states that when only those studies least susceptible to
bias are included, the evidence suggests that induced abortion
does not increase a woman's risk of breast cancer. The Guideline
can be obtained from the RCOG bookshop@rcog.org.uk
