Why does having an abortion so greatly increase the chance of getting breast cancer?
When you first become pregnant (before you even know you are pregnant), your body does many things to prepare you to carry and take care of a baby. One thing done is to increase the tissue in the breasts. When the new tissue first grows in, it is, what the doctors call, ‘undifferentiated’ meaning that it’s not really breast tissue yet. During the pregnancy for several months, your body changes this new tissue to breast tissue to prepare you for nursing your baby. When you have an abortion, you become ‘unpregnant’ in five minutes (most early abortions like suction abortions). This confuses your body and it doesn’t get rid of the ‘undifferentiated’ tissue it has formed in your breasts. That tissue remains there and is a prime candidate (like any stray growth) for breast cancer.
