Radiofrequency ablation

Radiofrequency ablation is a treatment that uses heat to destroy multiple small tumors. An interventional radiologist  makes a tiny incision and uses either a computed tomography (CT) scan or ultrasound to guide a special needle to the site of the tumors. Next, radiofrequency (RF) electrodes are placed into the tumor. The electrodes generate an electric current (RF energy) which is transformed into heat, destroying the tumor. This technique can be repeated at multiple sites, as necessary, before the interventional radiologist removes the RF electrode.

After the treatment, patients will follow up with their physician for several months. The treatment team will also order additional imaging scans to evaluate whether the radiofrequency ablation was successful in destroying the tumor.
