Funny you should mention cancer.    Should I tell you about my mom and my youngest brother that you probably would have murdered because my mom had cancer?  Brain cancer for her.   She survived his birth by 25 days.   I know about cancer and births and heartaches.   I ended up being his guardian as my dad died a couple of years after her.
I have sympathies for the ladies you mention.   The problem is they are the minority of the baby killers.   Most of the babies killed are for other reasons.
