Breast lifts as a way of balancing the breasts after mastectomy and reconstruction are very common, but the key is the timing of the procedure. Looking at your photos, I would be very surprised if you need much of a lift on the right side, if any, and I would definitely not touch the right breast until we know exactly what the size and shape of the left side will be-- this is hard to predict before the mastectomy, so waiting is often the best option.
The choice to do an immediate versus delayed reconstruction is a personal one, and some surgeons only do one or the other-- as a group we're divided on this issue for a lot of reasons, but assuming your doc feels that you are a good candidate for this, I think it can be done.
My usual plan in these situations is:
Procedure 1: Use of a tissue expander with the skin substitute Alloderm on the left side, performed as the first stage of the reconstruction at the time of the mastectomy (this is called an immediate reconstruction, and while many patients are not good candidates for it based on their anatomy, I think you are, as long as you don't have a high chance of needing radiation after the procedure). The Alloderm acts as a sling to hold the expander in a nice position, and is placed under your skin.
Your expander is filled with saline each week or two to expand it, creating the size and shape of a breast.
Procedure 2: On the left side, we would remove the expander and place a soft implant, usually a silicone gel implant. At this point, we will know what your right side needs in order to get you the best balance: a lift, an implant, a lift plus implant, or maybe even nothing. (this is an outpatient procedure-- no need to stay overnight in the hospital)
Procedure 3: Creation of a nipple on your left breast-- this can be done in the office with just some numbing medicine; this nipple can be tatooed later on to match your right side.
I hope that helps-- talk to your surgeon carefully before agreeing to have anything done on the right side and find out what the goals of that procedure would be.
