Radiofrequency ablation (RFA) is a minimally invasive procedure that destroys cancerous tumors. Pulses of radiofrequency energy are sent through a catheter (a long, thin tube) to heat and destroy diseased tissue. Currently, RFA is a standard treatment for patients with inoperable liver tumors.
RFA may be used for patients who have unresectable metastatic liver lesions, or are too ill to undergo surgical resection, and may be used in combination with other forms of treatment. Surgery Surgical resection involves removing a portion of the liver that contains the metastatic lesion.
