Hypothetically speaking...a married woman with 2 or 3 children is being treated for cancer. During her chemotherapy she discovers she's pregnant again due to birth control failure [for instance]...and with ongoing chemotherapy and chemo meds, there's a chance that the fetus will be attacked by them as well as by the tumor she's battling against... She's left with two options/alternatives: a. ...she can decide to abort the pregnancy and choose to continue with chemotherapy treatments. If she takes the chemo, she has a chance of surviving and making a full recovery. b. ...she can decide to cancel chemo treatments and continue with the pregnancy. If her cancer is left untreated, she could potentially die. What would be the right thing to do?
