Cryotherapy, also known as cryosurgery, is a commonly used procedure for the treatment of a variety of benign and malignant lesions. It uses a chemical, liquid nitrogen which is extremely cold to freeze and destroy the lesion.
How is it carried out?
The procedure is normally undertaken with a consultation. The liquid nitrogen is applied with a spray for a short time, directly onto the lesion being treated.
How is the affected area looked after?
Normally no specific care is needed. The area can be washed as normal. Occasionally area can blister and if this happens a dry dressing can be applied. Usually, the area will dry and heal over 2-4 weeks.
