re: abortion
Question from wondering on 04-09-2013:

Would a hysterectomy for a pregnant woman who has uterine cancer be double effect if the cancer has a chance to spread?

Answer by Judie Brown on 04-12-2013:

Dear Wondering

A hysterectomy during pregnancy is a direct act that removes the uterus and also kills the preborn child. As such it is a direct act of abortion and is not a question of the double effect principle.

Ethical physicians who are familiar with cancer of the female organs during pregnancy concur in the opinion that aborting the baby is not proper "treatment" for the cancer.
