Overview
Ablation therapy is frequently performed using a cryoprobe. A hollow metal probe, through which flows extremely cold liquid nitrogen, is inserted into the vagina and applied to the cervix and held in place for 5 to 10 minutes. This freezes, and thus destroys, the superficial tissues of the cervix which contains the dysplastic tissue.
