What I wrote about was the effect of an abortion on a woman's breasts. If you will read what I wrote carefully you will see that hormones open up the cells and ready them for their job. If they are not closed up they become vulnerable to things like cancer. It is a biochemical fact.
Yes, I did read it. My point was that in some situations, miscarriage and abortion are biochemically equivalent, especially when the cause of the miscarriage (genetic defect that causes the embryo to die suddenly; immune incompatibilities; placental abruption, for some examples.) It is also possible for a woman to be far more hormonally unbalanced and put into an unhealthy state from a miscarriage, than from the normal end of pregnancy (birth.) Miscarriage and birth are *not* automatically equivalent.
