You are right--surgery is always risky.  You are also right that when possible we should always choose the less intrusive and less risky option.  When the life of an unborn child is involved, however, we cannot opt for the less invasive approach for reasons obvious to all but abortion supporters.   While the child still dies even when the tube is cut, nevertheless the way you go about something matters as much as the outcome.  The ends do not justify the means.  A direct abortion is never morally justifiable.  an indirect abortion can be.

Profits, notwithstanding, an institution that is Catholic must adhere to the Faith.
