The available treatment options are: Cryotherapy (freezing) a freezing substance such as liquid nitrogen is used to freeze the skin surface causing blistering and peeling of the lesion. New skin appears in place of diseased after some time. This is most common easily performable procedure. Curettage (scraping) is the procedure in which cruet is used to scrape off damaged cells and affected tissue is destroyed with electric current. Application of local anesthesia is required for the procedure. Creams and ointments containing flurouracil are used to block essential cellular functions of cells of actinic keratosis. Imiquimod is a topical cream which modifies immune system stimulating it to reject precancerous cells.
