A brief explanation of Cryosurgery.

Cryosurgery is the use of extreme cold produced by nitrous oxide gas (or, in specific instances, liquid nitrogen) to destroy diseased tissue. The nitrous oxide or liquid nitrogen are circulated through a special instrument called a cryoprobe. The cryoprobe is fitted with a variety of specialized bi-metallic tips that allow contact with and penetration of the tumor. The super-cold probe freezes and destroys the immediate and nearby 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.
