Breast Lift of Good Breast After Unilateral Mastectomy?

Expander implant reconstruction means that your breast will be reconstructed in stages over time.   This means that your reconstructed breast will change in shape and size during the course.   It would be very hard to plan an appropriate "mastopexy" of your right, normal breast until the left side is completely healed and settled.   Why?  The mastopexy design will be dependent upon the overal result of the left breast.   It would be better for you to wait on the right breast until 3-6 months after the final procedure is completed on your left.  This will be your best chance at symmetry.

Thanks for the great question.
The simple answer is it is too early to be able to tell the best answer. Most symmetry operations after mastectomy and reconstruction are staged. This gives time for the reconstruction to settle and find its final shape as well as give you more of a chance to see what you desire and need for symmetry.
While multiple surgeries means a longer reconstruction process typically it produces greater cosmesis.
Typically "crescent" lifts have minimal power in truly lifting the breast.
Your insurance company should cover any symmetry procedures to the normal breast.
Take care of the cancer and the immediate reconstruction and then evaluate the overall shape and create a plan six months after your reconstruction.
I hope this helps.
