Not sure what to expect...

This is my first journey down this path so I'm hoping someone can give me some insight. Back in September after my yearly mamo my breast cancer was discovered.  Long story short after many failed attempts I've finally gotten my BRCA tests completed and received a call Christmas Eve that the results were negative.  My oncologist wanted the results to determine weather he was going to do a mastectomy or a Lumpectomy, so based on these results it looks like it'll be a lumpectomy with a breast reduction on my other breast.  I have an appointment Feb 6 to discuss the results and schedule the surgery.   I made a small list of my own questions for him, but naturally I don't know the unknown or even what to expect.  I'm hoping that someone could provide me with any questions to ask my oncologist, radiologist or plastic surgeon as I will be meeting with the team and have no idea what I'm in for.  Thanks in advance for any insight someone can provide me.
