Inverted Nipple - Is this something I need to worry about?

Although nipple inversion is a common issue, evaluation by a physician is warranted to ensure that it is not caused by an abnormality within your breast, most worrisome, a malignancy of your breast. Given your history of spontaneous eversion without difficulty and without other signs or symptoms, your instance is likely a benign finding.  A simple procedure to correct and evert your nipple is possible if you so desired.  However, I would wait until breast feeding and childbearing is completed.  Certainly, if it continues to progress, fails to evert with manipulation, or there is any drainage/bleeding, an examination with likely further imaging studies should be conducted urgently.  Hope that this helps!  Good luck!

Thank you for the question.
It would be in your best interest 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.
