Targeted Radiofrequency Ablation (RFA) is a minimally invasive procedure used to treat certain types of cancer. It uses high-frequency electrical currents to heat and destroy cancer cells. The procedure is typically performed with the help of imaging guidance, such as ultrasound or CT scan, to ensure that the cancer cells are targeted accurately. RFA is most commonly used to treat tumors in the liver, kidney, and bone, but it can also be used to treat other types of cancer.
