Cryosurgery is a medical procedure that uses extreme cold to destroy abnormal tissues, such as tumors or warts. This technique involves applying liquid nitrogen or other cryogenic substances directly to the targeted area, causing the cells to freeze and die. It is often used in dermatology and oncology for treating various skin conditions and cancers. The procedure is typically performed in a doctor's office and does not require general anesthesia. Patients may experience some discomfort during the treatment, but recovery is usually quick, with minimal scarring. Cryosurgery is considered a safe and effective option for many patients.
