Research has shown that women who have had at least one full-term pregnancy have a lower risk of breast cancer. In other words, having at least one baby after being pregnant for nine months lowers your breast cancer risk. Because of this protective effect of full-term pregnancy, some researchers wondered whether birth control pills or abortion would also have an effect on breast cancer risk.
Researchers at the Centers for Disease Control looked at the first part of the question and their results showed that taking birth control pills DOES NOT increase a woman's risk of breast cancer.
Now, a study shows that women who have had one miscarriage (spontaneous abortion) or one or more induced abortions DO NOT have a higher risk of breast cancer. Women who had two or more miscarriages had a slight increase in risk. The researchers didn't explain why this slight increase in risk happened.
Abortion is a very sensitive topic. This study supports earlier evidence that having an induced abortion or miscarriage does not increase a woman's breast cancer risk. We hope that by reviewing this study and others on this sensitive topic, we can help you feel more informed and secure about important health decisions you may face.
