After a Breast Reduction, what are the chances of breasts growing back?

and having a reduction doesn't prevent you from having fluctuations in your breast size post-op.  And if you ever experience marked growth of the breast size, you should see your doctor.

Breasts do not commonly grow after a reduction unless you put on weight or are still growing as a young adult. 

Hello, and thank you for your question.Once you have had your breast reduction, then you are the same as other women with breasts. In other words, some women have changes to their breast size during their lifetimes, as you have pointed out( due to things weight gain, and hormone influences). If you have had a breast reduction, you have the same chance as everyone else of this happening or not-happening to you. The fact that you have had your breasts reduced does not affect the other factors.In my 20+ years of practice, I have not seen many women present with this problem.I wish you well in your journey.
