What are the indications for radiofrequency ablation of liver cancer

Only about 25% of patients with liver cancer have a chance of being surgically removed. The limitations of surgery have led to the emergence of a variety of alternative treatments, and radiofrequency ablation is one of the most effective. Radiofrequency current passes through the RFA electrode needle unfolded in the tumor, inducing ion oscillation in the tissue around the electrode needle, and friction heat generation occurs a few minutes later, which increases the temperature of the tumor tissue to 80-110 degrees, directly causing coagulation necrosis of tumor cells.
