Radio Frequency Ablation (RFA)
In radiofrequency ablation (RFA), the interventional radiologist guides a small needle through the skin into the tumor.
Radiofrequency energy (similar to microwaves) is transmitted to the tip of the needle, where it produces heat and kills the tumor near the needle. The tumor remains as a mass or scar of dead tissue.
RFA is ideal for nonsurgical candidates and those with smaller tumors.
