Abstract: Thermal ablation is direct application of heat to a specific tumor in order to achieve complete eradication of tumor There are five methods used to produce thermal ablation: cryoablation, radiofrequency (RF), laser, ultrasound and microwave (MW). The thermal ablation received more attention from research community when they realized its potential to become the superior treatment modality with the advancement in technology. In this paper author has compared the entire thermal ablative to treat the cancer in the deep seated organs.
