Radiofrequency ablation kills cancer cells by heating and destroying them. The physician inserts a thin needle guided by computed tomography (CT) or ultrasound through the skin and into the tumor. Electrical energy delivered through this needle heats and destroys the tumor. Months after the procedure, dead cells turn into a harmless scar.
Advantages of radiofrequency ablation include:
- Effective treatment for small tumors
- Minimally invasive, with no skin incision
- Minimal risk to patient
- Typically little or no pain
- Minimal hospital stay
- Can be repeated if new cancer appears
