Radiation Oncology

The Radiation Oncology Department at Medical Park offers cutting-edge cancer treatments using the latest radiotherapy technologies. Our dedicated team of radiation oncologists, specialists who plan and calculate precise radiation doses, and experienced nurses work together to provide personalized care for each patient. We focus on targeting tumors effectively while protecting healthy tissues, aiming to optimize treatment outcomes and maintain quality of life.

Radiotherapy works in two main ways. Some cancer cells are directly affected by radiation and die quickly, while others sustain DNA and chromosomal damage that prevents them from dividing, ultimately leading to cell death. Although healthy cells can also be affected, they typically recover over time and regain normal function.

Advancements in technology have significantly improved radiotherapy, making it one of the most effective cancer treatments today. Modern radiotherapy focuses on delivering the precise dose of radiation to the tumor while minimizing exposure to surrounding healthy tissues. Achieving this balance was difficult with conventional methods, but new techniques now allow highly targeted treatments.

Three-Dimensional Conformal Radiotherapy (3DCRT)

Three-dimensional conformal radiotherapy (3DCRT) is one of the most widely used advanced methods. Unlike conventional radiotherapy, which uses two dimensions (width and length), 3DCRT incorporates the third dimension—depth—through advanced computer software. This enables doctors to create highly accurate treatment plans tailored to each patient.

During planning and treatment, tumor volumes and surrounding healthy tissues are continuously evaluated in real time, ensuring the correct radiation dose is delivered. Multiple radiation fields are used to maximize tumor control while minimizing side effects on healthy tissues. This approach helps improve survival rates and maintain patients’ quality of life.

Intensity-Modulated Radiation Therapy (IMRT)

IMRT is an advanced form of 3DCRT that allows thousands of radiation beams to be precisely directed at different areas of the tumor. By adjusting the radiation dose for each target volume, IMRT delivers the highest possible dose to the tumor while protecting healthy tissues. Three-dimensional CT images are used to map the tumor and critical organs, allowing for precise treatment planning.

Although IMRT planning and treatment take slightly longer than conventional methods, it is preferred for cancers where precise tumor control and reduced side effects are essential. IMRT is commonly used for prostate, head and neck, breast, thyroid, and lung cancers, as well as gynecological cancers, liver tumors, brain tumors, lymphomas, sarcomas, and pediatric cancers.

Advanced Radiotherapy Equipment

Our department is equipped with state-of-the-art devices that are fully networked to minimize potential manual errors. Integration with our hospital’s PET/CT scanner allows precise identification of tumors and surrounding healthy tissues.

Linear Accelerator
We use Varian DMX Linear Accelerators capable of delivering photon energies of 6 and 15 MV and electron energies of 6, 9, 12, and 15 MeV. Multi-leaf and asymmetric collimators protect healthy tissues while allowing maximum radiation to the tumor. Electronic portal imaging ensures real-time monitoring and verification of treatment volumes during therapy.

Gamma Knife Radiosurgery for Brain Tumors

Gamma radiosurgery offers a minimally invasive alternative to open surgery for many brain tumors. It is highly effective and safe, with minimal side effects:

• No general anesthesia required

• Most patients go home on the same day

• No recovery period needed

• No scalp wounds or hair removal

• Minimal discomfort with maximum therapeutic benefit

• Healthy brain tissue receives minimal radiation
