Chemotherapy, surgery, and radiotherapy are the three basic treatments for cancer. Which one of these is used, depends on several factors. In addition to individual circumstances, the type, size, and position of the tumor are decisive for the chances of success of the treatment. Possible side effects and the acceptance of the treatment type by the patient also play an important role.
For many types of tumor, radiotherapy shows good chances of success and a high acceptance level. External, internal, and systemic methods for radiotherapy exist.
