While it's possible that there's a correlation between breast cancer and
abortion (or breast cancer and watching the Power Puff Girls), an actual
link has not been found. And that's fair to say.

If you know anything about cancer epidemiology, or indeed anatomy, you

know that it is totally impossible that abortion won't have some sort of
effect on breast cancer, one way or another.

The consensus is that abortion does not have an effect on abortion.
All the pro-aganda pushed by pro-liars is intentioal deception because
they will do anything, murder, lie, cheat and steal, to obtain control
over women.

Better than that, I'll give you a list of abstracts of studies on the
link between induced abortion and breast cancer, in chronological
order, since Jan 2000 (the Brind study was published in 1996). I used
PubMed, and the search string "Abortion, Induced/adverse effects"[MAJR]
AND "Breast Neoplasms/etiology"[MAJR]

My apologies for the lengthy post, but I have left the abstracts

Lazovich D, Thompson JA, Mink PJ, Sellers TA, Anderson KE. Induced
abortion and breast cancer risk. 1: Epidemiology. 2000 Jan;11(1):76-80

Results from case-control studies suggest that induced abortion may be
associated with a small increase in risk of breast cancer. While risk
estimates from cohort studies have generally not observed such an
association, these studies have had limited information regarding
abortion and possible confounding variables. Therefore, we conducted a
study among a cohort of post-menopausal women from whom detailed
information regarding pregnancy outcomes as well as risk factors for
breast cancer had been collected. The study sample included 37,247 Iowa
Women's Health Study participants, 55-64 years of age at baseline in
1986, who reported no history of breast, or other, cancer (except
non-melanoma skin cancer), and for whom information regarding pregnancy
outcomes (that is, live birth, stillbirth, spontaneous abortion,
ectopic pregnancy or induced abortion) was available. We used linkage
with records of the State Health Registry of Iowa, part of the National
Cancer Institute's Surveillance, Epidemiology, and End Results (SEER)
program, to estimate the incidence of breast cancer among cohort
members through 1995. We calculated age-adjusted relative risks and 95%
confidence intervals using Cox proportional hazards regression. Only
653 women (1.8%) reported an induced abortion. The age-adjusted
relative risk of breast cancer among women with prior induced abortion
compared with those without was 1.1 (95% CI = 0.8-1.6). Relative risks
were higher among women whose age at first abortion was less than 20 or
at least 30 years, for those whose abortion took place after their
first birth or who never gave birth, and for those with early
termination (0-2 months). These estimates varied from 1.3-1.7, but the
confidence intervals around each were wide. Since most women in this
cohort were beyond their reproductive years when abortion became legal
in 1973, the low prevalence of induced abortion argues for a cautious
interpretation.

cancer among parous women: a birth certificate registry study.
Epidemiology. 2000 Mar;11(2):177-80

We wished to assess the relation of induced abortion to the subsequent
incidence of breast cancer among parous women, using a design that
would prevent the possibility of differentially complete reporting of
abortion history by women with breast cancer and controls. Our study
was conducted within a cohort of women who gave birth to a child during
1984-1994 while residing in 13 counties of western Washington. Cases
were women from the cohort diagnosed with breast cancer between 1984
and 1994. From the remaining cohort members, five controls were matched
to each woman with breast cancer by year of index birth (ie, the last
child born before breast cancer diagnosis) and by age at delivery. We
categorized 463 cases and 2,201 controls according to history of
induced abortion as recorded on the index birth certificate. The risk
of breast cancer was not found to be associated with a prior induced
abortion (estimated relative risk (RR) = 0.9, 95% confidence interval
(CI) 0.7-1.2). These results suggest that an induced abortion, if
followed at some later time by pregnancy and childbirth, does not
increase a woman's risk of breast cancer.

Abortion history and breast cancer risk: results from the Shanghai
Breast Cancer Study. Int J Cancer. 2001 Jun 15;92(6):899-905

Studies of the association between induced abortion and breast cancer
risk have been inconsistent, perhaps due to underreporting of
abortions. Induced abortion is a well-accepted family planning
procedure in China, and women who have several induced abortions do not
feel stigmatized. The authors used data from a population-based
case-control study of breast cancer among women age 25-64 conducted
between 1996 and 1998 in urban Shanghai to assess whether a history of
and the number of induced abortions were related to breast cancer risk.
In-person interviews were completed with 1,459 incident breast cancer
cases ascertained through a population-based cancer registry, and 1,556
controls randomly selected from the general population in Shanghai
(with respective response rates of 91% and 90%). After adjusting for
confounding, there was no relation between ever having had an induced
abortion and breast cancer (odds ratio [OR] = 0.9, 95% confidence
interval [CI] 0.7-1.2). Women who had 3 or more induced abortions were
not at increased risk of premenopausal breast cancer (OR = 0.9, 95% CI
0.6-1.4) or postmenopausal breast cancer (OR = 1.3, 95% CI 0.8-2.3).
These results suggest that a history of several induced abortions has
little influence on breast cancer risk in Chinese women. Copyright 2001

The purpose of this Committee Opinion is to provide a review of recent
studies regarding the potential relationship between induced abortion
and subsequent breast cancer and to discuss methodologic challenges in
this field of study. The American College of Obstetricians and
Gynecologists' Committee on Gynecologic Practice concludes that early
studies of the relationship between prior induced abortion and breast
cancer risk have been inconsistent and are difficult to interpret
because of methodologic considerations. More rigorous recent studies
argue against a causal relationship between induced abortion and a
subsequent increase in breast cancer risk.

breast cancer: record-based case-control study. Int J Cancer. 2003 Feb
20;103(5):676-9

It has been suggested that abortions leave the breast epithelium in a
proliferative state with an increased susceptibility to carcinogenesis.
Results from previous studies of induced or spontaneous abortions and
risk of subsequent breast cancer are contradictory, probably due to
methodological considerations. We investigated the relationship between
abortions and subsequent breast cancer risk in a case-control study
using prospectively recorded exposure information. The study population
comprised women recorded in the population-based Swedish Medical Birth
Register between 1973-91. Cases were defined by linkage of the birth
register to the Swedish Cancer Register and controls were randomly
selected from the birth register. From the subjects' antenatal care
records we abstracted prospectively collected information on induced
and spontaneous abortions, as well as a number of potential confounding
factors. Relative risk of breast cancer was estimated by odds ratios
(OR) with 95% confidence intervals (95% CI). A reduced risk of breast
cancer was observed for women with a history of at least 1 compared to
no abortions (adjusted OR = 0.84, 95% CI = 0.72-0.99). The adjusted OR
decreases step-wise with number of abortions to 0.59 (95% CI =
0.34-1.03) for 3 or more compared to no abortions. The patterns are
similar for induced and spontaneous abortions. In conclusion, neither a
history of induced nor spontaneous abortions is associated with an
increased risk of breast cancer. Our data suggest a protective effect
of pregnancies regardless of outcome. Copyright 2002 Wiley-Liss, Inc.

Palmer JR, Wise LA, Adams-Campbell LL, Rosenberg L. A prospective study
of induced abortion and breast cancer in African-American women. Cancer
Causes Control. 2004 Mar;15(2):105-11

OBJECTIVE: There continues to be controversy about whether induced
abortion influences the risk of breast cancer. Because case-control
studies of this relation are subject to recall bias, there is a need
for prospective data. Further, there has been little study of abortion
and breast cancer in African-American women. We assessed the relation
of abortion to risk of breast cancer in a prospective follow-up study
of African-American women. METHODS: Black Women's Health Study
participants have been followed by mailed questionnaires every two
years since enrollment in 1995. Participants reported 348 incident
breast cancers during 205,983 person-years of follow-up. Women who had
an induced abortion were compared with women who had never had one,
with nulliparous and parous women analyzed separately. Incidence rate
ratios (IRR) with two-sided 95% confidence intervals (CI) were derived
from Cox regression models that controlled for age, age at first birth,
number of births, history of spontaneous abortion, and other factors.
RESULTS: Among nulliparous women, the IRR for any induced abortion
relative to none was 0.9 (95% CI = 0.5-1.4), and among parous women,
the comparable IRR was 1.1 (95% CI = 0.8-1.4). Risk did not vary by
number of abortions, age at first abortion, age at diagnosis or a
family history of breast cancer in either nulliparous or parous women.
CONCLUSIONS: Our findings indicate that induced abortion does not
increase breast cancer risk in African-American women.
