Radiation Oncology


Here, at the German Oncology Center (GOC), we operate a fully integrated Radiotherapy Department, where we apply some of the most advanced and specialized treatment techniques and procedures in cancer care.

From your very first visit, you’ll feel that for our professional team of specialist doctor’s and other medical and patient management staff, you will be the center of their focus, either for developing personalized treatment plans based on biological, anatomical and other characteristic features of every one of you, or for any other practical matters that will make you feel safe and comfortable.

Our Department is in close cooperation with, and supported by Molecular Biology and Genetics clinics, and our in-house Medical Oncology, Diagnostic and Interventional Radiology (3D-Ultrasound, CT Scan and MRI), Nuclear Medicine and Medical Physics Departments.

In line with international guidelines, we hold regular Oncology Board Meetings of all associated medical disciplines, so as to ensure that decisions concerning personalized treatments are objective and reliable.


The Radiation Oncology Department consists of two units, which work independently, meaning that each one can offer exclusive therapy treatment, but are also interconnected with combined therapeutic approaches. Both are supported by the GOC’s imaging facilities, and by specialized software programs for radiotherapy planning systems, which are worked out by our Medical Physics Department.


Equipped with 2, new generation, linear accelerators (LINAC), this Unit carries out all modern treatments using the most advanced radiation therapy techniques available (Intensity modulated radiation therapy – IMRT, Volumetric modulated arc therapy – VMAT, Image-guided Radiation Therapy IGRT), including Stereotactic radiation therapy and radiosurgery.

External radiation is also known as external beam radiation. The machines (linear accelerators), are used to aim high-energy rays (or beams) with precision and from different angles and levels, so that the necessary dose is delivered into the tumor, with the less possible burden to healthy nearby tissues.



Our comprehensive and technologically advanced Clinic for interventional radiotherapy-brachytherapy enjoys worldwide recognition. Brachytherapy is an internal radiation treatment, using radioactive sources. This is the main factor that makes it differ from external radiotherapy, where rays are administered to the patient from outside the body.

In High Dose Rate (HDR) Brachytherapy, small needles (catheters) are placed directly into or next to the tumor, under the image guidance of CT Scan, MRI, PET/CT, Ultrasound, and/or a combination of them. Tubes/cables will then be connected to the needles, and will link to a machine which stores the radioactive source (Iridium – 192). The source will then be administered to the patient for a specific time, which is calculated for the so-called “radiotherapy plan” by our Medical Physicists. With this very targeted and precise method, high-dose radiation is delivered right into the tumor, and at the same time the surrounding healthy tissues are well protected by it.

Brachytherapy can be applied, either independently or in combination with external radiotherapy, as a highly effective treatment for many types of cancer, especially prostate, cervical and breast cancer, soft tissue sarcomas, and also in liver and lung metastases.
