I can't imagine Dr's would promote "alternate therapies" for cancer patients. I think we all have choices and part of the research is finding the right carers to let you make your own choices, whatever the situation. I don't really see pregnancy as the hard done by minority group.
I have never found (3rd pregnancy) that I have ever been pushed or swayed to do anything except what I want. Maybe Im lucky, but I dont' think so. Most of my friends have done things "their way". If I have not been happy with something, I go elsewhere. The only issue I've come up against is the hospital wanting me out within 24 hours, but that is more a financial issue. I just went somewhere else.
