Microwave ablation (MWA) is the treatment using  image guidance to place a needle through the skin into a tumor.  In MWA, microwaves are created from the needle to create a small region of heat. The heat destroys the cancer cells. MWA are effective treatment options for patients who might have difficulty with surgery or those whose tumors are less than one and a half inches in diameter.
