It really depends on how much fatty tissue is now in your breasts since the breast reduction. Your breast could grow bigger due to excessive weight gain and/or pregnancy.
You might ask the doctor who told you that. Also, breast tissue is fat tissue. So, the more you keep fit all over, the less chance of them going back up.
