Although there has been some debate in the past about the link between abortion (also called induced abortion) and breast cancer risk, research clearly shows no link between the two . Since 2003, the Board of Scientific Advisors and Board of Scientific Counselors of the National Cancer Institute (NCI), as well as the American College of Obstetricians and Gynecologists, have agreed the scientific evidence does not support a link between abortion and breast cancer [451-452]. The NCI routinely reviews the evidence on this topic and continues to agree the evidence does not support a link between the two .
The importance of study design for research on abortion and breast cancer risk
Some case-control studies have suggested abortion may increase the risk of breast cancer . However, the nature of case-control studies makes the accuracy of their results questionable.
Case-control studies rely on the reporting of past behavior. When it comes to a sensitive topic like abortion, this can have a big impact on the information gathered. The cases in these studies (the women with breast cancer) may be much more likely to give complete information about their abortion history than the controls (the women without breast cancer). Such differences in reporting can bias study results.
Prospective cohort studies are much more likely to give accurate results on the topic of abortion. These studies gather sensitive information before women are diagnosed with breast cancer. This helps limit biased reporting. The results from cohort studies show abortion does not increase the risk of breast cancer [451,455-462].
Until they admit that there is at least a possible correlation or link I will still not support them.
Ditto! In fact, I would take it to the next level and include artificial contraceptives and abortion. It doesn't take a ton of costly research to see the growth in breast cancer among women on artificial birth control.
