Inverted nipple typically is a benign condition that people are borned with.  It’s uncommon but an inverted nipple can be caused by underlying breast pathology including cancer.  However, this is usually a change in the nipple position and will need further workup.  In cases where the nipple is formed inverted, this can be corrected with inverted nipple correction procedure.  This procedure is performed under local anesthesia in the office.  The stitches around the nipples will be removed at 2 weeks and 3 weeks after surgery.  After that a projective dressing is kept around the nipple for another 2 weeks to allow complete healing.  There is a chance that you might not be able to breastfeed in the future, so this must be taken into consideration when you want to pursue the procedure.
