This is from the National Institutes for Health National Cancer Institute:
On March 3, 2003, the National Cancer Institute's (NCI) Board of Scientific Advisors and Board of Scientific Counselors reviewed and unanimously accepted the findings of an "Early Reproductive Events and Breast Cancer Workshop." The workshop, convened by NCI, brought together a cross-section of experts to discuss available scientific data on reproductive events in a woman's life that may impact her subsequent risk of developing breast cancer.
Some of the population-based findings in the report that were presented as supported by evidence that was well-established were:
Early age at first full-term birth is related to lifetime decrease in breast cancer risk.
Increasing parity (number of live births) is associated with a long-term risk reduction, even when controlling for age at first birth.
The additional long-term protective effect of young age at subsequent term pregnancies is not as strong as for the first term pregnancy.
A nulliparous woman (someone who has never given birth to a live infant) has approximately the same risk as a woman with a first term birth around age 30.
Breast cancer risk is transiently increased after a term pregnancy.
Long duration of lactation provides a small additional reduction in breast cancer risk after consideration of age at and number of term pregnancies.
Induced abortion is not associated with an increase in breast cancer risk.
Recognized spontaneous abortion is not associated with an increase in breast cancer risk.

"Some anti-choice organizations have worked hard to stir up fears that abortion causes breast cancer even though there is a strong consensus in the scientific community that no such link exists. Anti-choice groups promote these scientifically unwarranted conclusions as if they were established facts in order to frighten women and discourage them from having an abortion. Anti-choice activists are opposed to legal abortion under almost any circumstances, regardless of its safety. Their real goal in this controversy is preventing women from exercising their legal right to choose abortion, not protecting women's health. "
