There’s no certainty to this concern. It depends on each specific case. Your surgeon will attempt to conserve as many milk ducts as possible, but everything comes down to your particular inversion and the technique that can be used. If you intend to breastfeed and have a less severe case of inversion, it is recommended that you perform the surgery after you have finished breastfeeding. But, if your grade of inversion prevents you from breastfeeding or may bring other complications, it’s recommended to evaluate with your surgeon which route makes breastfeeding more possible for you.
