Microwave ablation (MWA) is the application of electromagnetic waves to treat solid tumors. By causing oscillation of polar water molecules, microwaves produce frictional heating and ultimately induce cellular death via coagulation necrosis. This technique has been largely used for the treatment of tumors in the liver, kidney, lung, and bone.
