What if nipples are inverted at age 15? Is it a cancer?

I appreciate your question.This is most likely a normal phenomenon especially at your age.  However, I would recommend an exam if there is any change in your breast.The best way to assess and give true advice would an in-person exam.Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery.best of luck!Dr Schwartz

Inverted nipples can occur in teenagers during puberty as well as in adults and this may be completely normal.  I recommend that you see your gynecologist and discuss with him or her what your concerns are to make sure that this is normal.
