There is a moral guide on this and similar issues called the principle of double effect.
Using this principle, one can find that the woman can receive treatment to regain her health which can result in the death of the fetus, but only if the intent of the treatment is directed only toward the good effect of the woman regaining her health and that she have sufficient reason to act. The woman is not necessarily expected to die.
In order to employ this principle…one must go through the qualifications of the specific moral issue at hand.
- The course of action must be either good or neutral.
- The good effect of the action must follow the action at least as immediately as the evil effect. (If the good effect comes later, then, one has broken the moral precept not to do evil in order for good to come of it.)
- The intent must be directed solely to the good effect of the action.
- There must be sufficient reason to permit the evil effect of the action. The good effect MUST outweigh the bad effect.
I hope this helps you in the future as well as now!
