A woman's choice...

I am thoroughly confused how it is a woman's right to choose an abortion (which not only ends a life and is very bad for a woman's body physically) because "it's her body and she knows best" but it's not her right to pick an elective c-section (of course I am referring to one after 39 weeks). It's still my body isn't it? I'm not arguing the right or wrong of abortion by the way or the best way of giving birth natural or c-section. I'm simply saying it seems hypocrital. Thoughts?
