You should understand that you are not paying for the procedure but for the experience of the doctor. That being said the price varies from one place to another, whether you are doing it in a tier 1 or tier2/3 city; what adjunctive procedures are done such as Biopsy, or other diagnostic tests etc. To get an idea, you can consult a few other doctors to know the “price”. But I think, more importantly you should have trust in the doctors you are seeing, since that will more valuable than any price you pay.
