Cryotherapy provides a low risk and fast way of treating certain skin lesions. In many cases the predominant reason for seeking removal is because the skin lesion is unsightly or embarrassing. In the case of viral warts, cryotherapy treatment can reduce the chance of spread to other areas of the skin. In some cases skin lesions can become a nuisance through inflammation, itching, or catching on clothing, which provides another common reason for people seeking treatment for removal.
