You should be able to have the docs you want. However, if you have two who won't play nice together, I suppose that's worth considering. Is your Surgeon's preferred PS OK? Or should your Surg be given the boot for one who can play nice with your chosen PS? Honestly, when you are facing chemo, cancer, surgery, recovery, your Surg should be ashamed of herself. Quite unprofessional to have these deal-or-no-deal alliances and hold you captive to them.
