[The role and future of radiotherapy in cancer treatment]

Abstract

The basic principle of radiotherapy for cancer patients is that it has the possibility of a good result (curability), is tolerable and promises a comfortable life thereafter. Radiotherapy is the important tool for early stage cancer by conserving the organ and function and for an advanced or recurrent stage of cancer by helping improve the quality of life. Radiotherapy must be planned on the basis of considering the therapeutic ratio with a 3-dimensional technique. It should be performed with optimum radiation methods in the multimodal treatment of cancer and will undoubtedly prove effective in the future.
