Cryoablation
There are many tumor ablation techniques. Radiofrequency ablation (RFA) has been around for the last 16 years and we have used it for bone tumors such as osteoid osteoma, osteoblastoma and chondroblastoma and liver, and lung malignancies, with good success. However, RFA uses thermal energy and the exact diameter of ablation always remains a guestimate.
Cryoablation is a new technique where freezing temperatures are used to kill tumor cells by creating ice-balls within the tumors.
