Radiofrequency Ablation

Radiofrequency ablation (RFA) is a common way to treat cancer tumors with heat. It uses high-energy radio waves for treatment. A thin, needle-like probe is put into the tumor for a short time, usually about 10 to 15 minutes. Placement of the probe is guided using ultrasound or CT scans. The probe puts out a high-frequency current that creates heat (between 122° and 212° F) and destroys the cancer cells within a certain area.
