Cancer is one of the most deadly diseases of our century. There are three basic methods of cancer treatment; chemotherapy, radiotherapy and surgery. Doubtless, radiotherapy is the most different approach for the patient because the patient and patient’s relatives have difficulty in understanding what are the rays used in radiotherapy and how they affect the patient. On the other hand, it is more influential than radiotherapy in the local treatment of cancer, and what’s more it is a painless treatment method. It is, however, very important that this treatment should be applied by the trained and well-equipped personnel. With this importance and necessity in mind, the Program of radiotherapy was founded in Nisantasi University also parallel to the developments in the world. The basic purpose of the program is to train health technicians who are qualified and equipped with the background and skills to control the equipment and materials, prepare the mask, patient position pattern, lead block and patient for treatment and simulation, and do the radiotherapy and simulation. Health sector is among the top professions where there is a sustainable source of employment. Thus, radiotherapy is one of the fields with a wide range of employments. The graduates of the program are entitled to work as ‘radiotherapy technician’ at hospitals, private clinics and radiotherapy centres of public and private sector.
