Radiofrequency Ablation (RFA) is a minimally invasive procedure used to treat tumors by using heat to destroy cancer cells. Guided by imaging, a needle-like probe is inserted into the tumor site, delivering radiofrequency energy to generate heat and ablate the targeted tissue. RFA is commonly used for small tumors in the liver, lungs, kidneys, or bones and is performed under local anesthesia or sedation. The procedure is effective, with minimal damage to surrounding tissues and a short recovery time.
