Radiofrequency ablation (RFA) is a new technique for the treatment of cancer that began in the liver or cancer that spread to the liver from another organs as well as inoperable liver cancer. The procedure is not complicated, with only few side effects, utilizing thermal ablation to destroy the target tissue via a needle.
 
The radiofrequency ablation equipment normally consists of radiofrequency (RF) energy generator, radiofrequency needle and ground pad. The radiofrequency energy generator and the types of radiofrequency needle have been designed differently based on each manufacturer, but with the same purpose to transmit thermal energy into the cancerous liver tumor thoroughly.
