No one should be pressuring women either way.
To me, this would be the ideal sequence of events:
Doctor explains the likely prognosis, including the levels of uncertainty (because women aren't idiots, and we can factor uncertainty into our decision making)
Doctor presents abortion as one of the valid choices at this stage.
Pregnant women who want to proceed with the pregnancy are not mortally offended by the word abortion, because they understand that other pregnant women will need this option. These women just say "no thank you abortion is not for me", and then the doctor says "absolutely fine, that's a perfectly valid decision. If you change your mind, or if you have doubts, then please know that you can raise this again at any point".
Women who wish to end the pregnancy are similarly told "absolutely fine, that's a perfectly valid decision. We'll book you in for X days time, you can of course change your mind, or discuss this further, at any point up til then".
