Except for the most extreme cases your nipples are not removed during the procedure.Your nipples are left attached to the breast tissue which we keep and fashion your new breasts from. If you required a reduction of upwards of 2kg/side (4kg in total) then we may discuss whether a free nipple graft technique is appropriate. This is a very rare circumstance. Most breast reductions are 500 -1800 grams removed each side and removing the nipples is not an issue.
This depends on the individual person. Fatty deposits on the lateral chest are not strictly speaking likely to be breast tissue but are common nonetheless. If you are not at your ideal body weight this is more likely. We will discuss this issue at your consultation if it is relevant to you. If fatty deposits are present then most often we use liposuction to try and decrease these for you.
It is very rare. I have performed 2 repeat breast reductions in my career. Both women had their previous reductions performed by another surgeon, over 25 years before hand. Both women had experienced significant breast regrowth at the time of menopause having had thier original breast reduction procedure when they were young women.
