Cryotherapy is a medical procedure that uses the application of very low temperatures to treat abnormal skin conditions that include skin warts and skin malignancies. This technique is also used in treatment of precancerous cell changes in the uterus and in treating some cases of cancer of the prostate.
Medical equipment to carry out these procedures is produced by medical equipment manufacturers for use in physician office practices and in medical clinics. The most common cold agent for use in cryotherapy is liquid nitrogen, which is available through a variety of application methods and storage containers.
