While seborrheic keratosis is generally harmless, it can be unnerving to find a new lesion on your skin, especially if it appears on the face. Your doctor may suggest a number of options to remove the growth, especially if it bleeds or becomes irritated. These options include:
Cryosurgery in which the growth is frozen using liquid nitrogen. However this procedure may not work on large, thick growths and cause the lightening of skin.
Electrocautery in which the growth is burned using an electric current. This procedure may be done alone or in combination with curettage and can cause scarring if not done properly.
Curettage in which the skin’s surface is scraped using a special instrument. It can used in combination with cryosurgery or electrocautery
Ablation in which the growth is vaporized with a laser
At times, there may be the need to go for skin biopsy to rule out any possibility of skin cancer
