What is ablation for kidney cancer?

Usually, kidney cancer (also called renal cancer) is treated with surgery to remove all or part of the kidney. However, other options may be used in certain situations, particularly when a patient has other medical problems that make surgery unwise.

One relatively new treatment is ablation, which uses cold or heat to attack a tumor. When cold is used, this is called cryotherapy or cryoablation. When heat is used, this is called radiofrequency ablation.
