Do you take the same attitude towards a woman in her thirties, who already has children and goes ahead and gets pregnant again, despite already having had breast cancer? She’s got an even higher chance of leaving her children without a mother in a very few years, but most FReepers seem to regard that sort of thing as heroic.
Your question is just peculiar. Why would it be "heroic" in such an instance? I do think it's heroic when a pregnant woman finds out she has cancer and puts off treatment until after the birth of the child.
I don’t know that anybody here’s said that an intentional pregnancy for a woman with cancer is “heroic”.
Nutjob lady went out of her way, including LYING to the fertility clinic about her age, to get pregnant.
Her risk of having disabled children was substantially higher at her age but, dammit, she wanted children.
