Combining the latest image-guided radiological and surgical techniques, radiofrequency ablation (RFA) uses a thin wire probe, inserted directly into tumors, to heat and kill cancer cells with electrical current.

This fascinating episode of "Healthy Body, Healthy Mind" features Dr. Damian Dupuy, who has pioneered the use of ablation to treat lung cancer in the United States.
