Cryosurgery is the use of extreme cold produced by a liquid nitrous oxide gas (or, in specific instances, liquid nitrogen) to destroy diseased tissue. The super-cold probe freezes and destroys the immediate and surrounding cells. After cryosurgery, the frozen tissue sloughs off and, in most cases, is replaced partially or completely with healthier scar tissue. Think of cryosurgery as controlled frostbite.
Ask your VCA veterinarian if Cryosurgery is right for your pet.
