In RFA, high-frequency electrical currents are passed through an electrode in the needle, creating a small region of heat. … The heat destroys the liver cancer cells.

Is microwave an ablation?

A new technology, microwave ablation (MWA), destroys liver tumors using heat generated by microwave energy.
