Radiofrequency ablation (RFA) is a procedure in which a surgical oncologist uses a small probe to deliver heat from radiofrequency energy to kill cancerous tissue. The procedure is used to treat liver, prostate, renal, bone and breast cancer.
RFA can be a valuable alternative to surgical kidney removal for cancer patients with multiple tumors, limited kidney function or only one kidney, or for patients who cannot risk surgery because of other health problems. The use of ultrasound and laparoscopic guidance, combined with impedance (resistance to electrical current) and temperature monitoring, allows for a safe, effective ablation.
Benefits of RFA include a shorter recovery time and less pain than experienced with surgery.
