I need a removal of an accessory nipple. How much will it cost? Doctor in my city?

Thank you for sharing your excellent question.  In most cases an accessory nipple can be removed for a few hundred dollars but this will vary by surgeon and geography.  Though I can not recommend any one surgeon I have attached a link below that should be useful in your search. 

Dear jmak,
the cost of surgery depends on a lot of factors (type of surgery, number of treated areas, anesthesia fee, surgeon, facility fee, city, etc.). It would be the best to visit or call plastic surgery offices and ask for a price.
