@engineer,
To discuss prostates and breasts in the same context might be adding apples to oranges, since many a slow growing prostate cancer can let a man die of other causes, while a cancer in a breast does not afford a women that luxury.
Plus, the problems remaining after prostectomies is far different than the problems remaining after mastectomies.
Perhaps, the conservatives that are anti-public option have the simple point that many people were happy with what they had. Like the saying goes, if it is not broken, do not fix it. The government wants to "fix" health care for everyone. It is not broken for everyone; only some people, and fixing it for them will just be raining on the parade, so to speak, on those that do not want it fixed, in my opinion.
You said more is not always more; well, more fixing is not always more (better) health care for more. Your analysis paradigm can be applied to the respective populations too of those that want health care fixed, and those that have no need to have it fixed for them.
Fixing health care for everyone is just the ruse, I believe, to make health care affordable to those that do not now have health care.
