Cryotherapy

What is Cryotherapy?

Cryotherapy involves the controlled use of liquid nitrogen to destroy pre-cancerous spots or benign growths. Your PC Dermatology provider  will utilize special equipment to expose the desired spot to liquid nitrogen for an appropriate treatment length, depending on your diagnosis, and the location. 

The liquid nitrogen freezes the tissue, and as the tissue thaws the abnormal or diseased tissue is destroyed at a cellular level. Your care team will explain everything in detail before starting, and you will be given detailed instruction on the after care.

​The cold does sting for a few seconds during therapy. It is normal to develop a blister or scab afterwards. Some lesions, such as warts, may require repeat treatments.
