The only concept to which abortion (or more appropriately stated, the ending of pregnancy) may be even considered a right for a woman is in regards to self-defense ... and that concept extends to ending a rape pregnancy or that of a minor child. BUT, and this the vital corollary, such ending of a pregnancy must be done earliest possible date in the lifetime already begun. [Donning my flame suit now ...]
Self-defense may be a natural right, but only in response to another life being in direct and immanent threat of dying in an otherwise unforeseen way.
... and that concept extends to ending a rape pregnancy or that of a minor child.
No it doesn't. Murdering the child of a rapist for a father's sins is no more justified than enslaving your child now for you great-great-grandfather's ownership of slaves (just guessing about your ancestry merely for the sake of the argument). The only thing such an abortion would accomplish is to make a victim of rape into a murderer of her own child.
BUT, and this the vital corollary, such ending of a pregnancy must be done earliest possible date in the lifetime already begun.
The inviolability of innocent human life is not dependent upon age. The moral culpability is identical if the human "lifetime has already begun."
