Karen, I haven't gone through the surgery yet (it's on Thursday), but my doc (one of the best around) advocates the surgery as a necessity. My personal view is that I want them to do everything possible to kick this bitch to the curb so it doesn't come back, and he is of the same view, so surgery first, then the the chemo/rad to kill off the stragglers.
Not sure if that helps as I haven't been through it yet, but for what it's worth, that's my view.
All my best to you!
