Cryotherapy (also known as cryosurgery) may be described as the use of extreme cold to destroy abnormal or diseased tissue. For our articles' motives, cryotherapy is a method where a chemical, usually nitrous oxide or liquid nitrogen is used to freeze off genital warts (or warts normally). It's most commonly recommended because this is a relatively inexpensive and effective treatment that is fast, in several situations and typically rather painless, very effective if there are only a number of warts present.
