Is it critical to have the pre-operation appointment for breast reduction surgery, at most, two days before surgery?

Each surgeon has their own protocols for their surgery patients. I see my patients preoperatively 2 weeks prior to surgery. At that time I give them their prescriptions and a lab test request. We review how the surgery is to be done, schedule the post operative appointment, answer all patient questions.  I do the markings right before surgery. I suggest that you write your questions down as it is easy to forget when you are at your appointment. Good luck.

Some anxiety prior to proceeding with breast surgery is normal. As long as you have chosen your plastic surgeon carefully and have communicated your goals careful as well, you should do just fine. Exactly when the preop visit is carried out and when the markings are performed does not matter; this varies from one practice to another. Best wishes for an outcome that you will be very pleased with.

Having a pre op appointment one week prior to breast reduction is appropriate. In my practice, we perform pre op's 1-2 weeks prior to surgery; giving patients plenty of time to pick up prescriptions before surgery, shop for items on their pre/post op shopping list and getting any pre operative lab work done. 
In regards to surgical markings, your surgeon will be able to talk more in detail about drawing on you at a pre op or on surgery day and how to keep markings in tact. 
Best of luck!
