Thank you for the question.
I'm glad you are scheduled to see a physician for consultation; although rare nipple inversion can be a sign of malignancy of the breast.
Inverted nipples can cause functional problems for women and emotional concerns. An inverted nipple can look flat or a slit like depression or hole at the normal nipple location. There are different degrees of inverted nipples possible. Whether a patient is a candidate for correction of inverted nipples depends on the extent of the problem.
Usually correction of the inverted nipples involve division of the lactiferous (milk ducts). The risks of the procedure include potential loss of sensation, inability to breast-feed, recurrence of the asymmetry and the potential need for further surgery.
My advice to patients go something like this... If the nipple is permanently inverted and does not evert with stimulation, then it is a useless nipple when it comes to sensitivity and/or breast-feeding. In these cases correction of inversion is indicated (because the potential gains outweigh the risks outlined above). On the other hand, if the nipple does evert spontaneously with or without stimulation, then I am more reluctant to perform the procedure given that the risks may outweigh the potential benefits. At that point, the decision is the patient's to make after careful consideration.
I hope this helps.
