Breast inversion braces are effective. However, if the breast inversion is more serious, it needs to be corrected by surgery. Breast inversion may be caused by congenital developmental abnormality or local inflammation, tumor or other diseases that cause pathological tissues to invade the breast ducts, ligaments and fascia. If breast inversion is not particularly serious, it can be improved by braces. The braces can suction and pull the nipple, and can make the internal ducts and smooth muscles elongate, which can improve the phenomenon of breast inversion by persisting for a long time. However, if breast inversion is more serious, the use of braces can only achieve the auxiliary effect, and it is necessary to combine with the condition of the breast and improve it through surgical methods. However, the surgery may cause internal scar formation, resulting in recurrence of the inversion.
