...Terminations are allowed in the case of ectopic pregnancies because BOTH mother and child would die.
No, this is not worded at all correctly. The procedure is *not *a "termination," nor is it permitted because both mother and child will die.
In the case of an ectopic pregnancy, the baby is attached to the tube rather than to the womb. The tube then poses a danger to the mother and needs to be removed. Unfortunately, and not as an intention, a side-effect is that the baby will also be removed and then be unable to survive.
The principle is that of double effect: the action is not in and of itself immoral, but a side-effect, which is not the end of the action nor intended, is an outcome one would not want.
In the case of pregnancy, if a woman is found to have cancer while she is pregnant, she can be treated with radiation or chemotherapy, as these are the normal, moral treatments. It may be that the treatment could kill the child, but this would not be the intention of the treatment, nor would the death of the child be the "end," or goal-implicit-in-the-action, of the treatment.
