Thanks for the query. Seborrheic keratosis is a very common skin condition and can be removed by multiple procedure depending on the size and location and the desire for final cosmesis. To name a few, electrocautery, radio frequency , cryotherapy and curettage. The Dermatologist will suggest a treatment option based on the body part affected and considering merits and demerits of each procedure. The cost should be around 1500-2000 but may be variable. Hope it helps you.
