CRYOTHERAPY
WHAT IS CRYOTHERAPY?
Cryotherapy is a second line verruca treatment which involves applying liquid nitrogen onto the lesion to destroy the affected tissues. The amount of time taken to freeze the area will vary depending on its size and location, with larger lesions requiring more treatment. Firstly, the lesion will be reduced with a scalpel. Once the area has been frozen a small scab or blister usually forms. It uses extreme cold therefore can be an uncomfortable procedure, some discomfort can also be expected a few days after treatment.
How does cryotherapy work?
Cryotherapy works by causing the cells which make up the lesion to rupture thus releasing the antigens which make up the virus into the blood stream. Once the virus is in the blood stream it is recognised by the immune system and an immune response is triggered to fight off the infection. Usually, a number of treatments are required at around monthly intervals. As with any verruca treatment options it is not 100% guaranteed to work.
