Depending on the piercing, we will often tape piercings with steristrips rather than removing them. If that's not possible, you could ask your surgeon to replace your piercing in recovery to avoid having to be repierced. Good luck.
Thank you for your question. Mastopexy involves rearranging the breast tissue to give a more "lifted" youthful appearance. Depending on the type of mastopexy performed this may also involve rotation of the nipple. Therefore if your piercing was "side to side" or "horizontal" it might end up "vertical" or "up and down". I would not be concerned about the piercing closing but the repositioning of the nipple may alter your piercing's angle. Make sure you consult with a surgeon certified by the American Board of Plastic Surgery and he/she can go over the risks and benefits of a breast lift.
