@mygoodgirls,
Depending on the surgeon's style, I usually let them discuss/inform me. Then I review my prepared questions to see if everything is covered.

The topics the members mentioned are helpful. Especially having another person present to help listen. You can also ask if the provider is OK with recording the appointment. Most smartphones can record.

The Susan Komen Breast Cancer website has a list of topics and possible questions. The section on "Treatment" addresses questions about surgery.

MedicinePlus also has a list of questions:

Have you had genetic testing? The results may impact the type of surgery they recommend.

One important question to ask is "How (who) do I contact if I have additional questions?"

Not sure if this is on the list of questions on the web page, but I am always concerned about "What's Next?" After surgery, ask what the treatment plan is and who will oversee it going forward. In my case, the surgeon saw me a few times after surgery to make sure of healing, but my oncologist handled all the continuing treatment and rechecks.

Wishing you the best.
