The number of microwave treatment is decided according to the size of the lesion. At present, microwave is more widely used for tumor treatment, and there are more and more case presentations in its related papers, literature, promotion in tertiary hospitals and related academic conferences, and currently China is in the forefront of international microwave treatment. If the lesion scope is small and the tumor load is relatively small, a single treatment can achieve radical effect. If the tumor load is large and the tumor body is also large, such as the diameter is greater than 5-8cm, single treatment may appear tumor residual, need to timely review after treatment, evaluate the treatment effect and determine the time of treatment again, generally 1-2 times can achieve the expected treatment effect.
