Abortion is the medical expression of abortion. It may be a spontaneous abortion, aka a miscarriage, or an induced abortion, which may be surgical or medical. A D&E is a possible abortion procedure but is also used when the foetus is already dead. Both D&E and D&C are just acronyms for different ways of clearing the uterus and its lining. Neither of them is exclusive to abortions nor do either of them mean the same thing as abortion.
It is true that nobody reads your posts in order to learn. This is because your ignorance and inaccuracy are so well-known that you are incapable of teaching. As you demonstrate in your post, your medical knowledge is miniscule and is limited to a hurried misreading of what you have gleaned from the Internet.
