Breast cancer
I want to express my deep gratitude to Professor Ugur Selek for his attentive attitude and professionalism. From the very first appointment, he carefully reviewed all my test results and explained each stage of the upcoming treatment in clear language, without complex medical terms. During radiation therapy, he constantly monitored the process, adjusted the regimen when necessary, and was always available. Thanks to his approach, I felt confident and at ease, and now there is steady positive progress. 02/11/2025

Lymphoma
Professor Selek made the impression of a very composed and attentive specialist. During the consultation, he did not rush, thoroughly reviewed all the examination results, and offered several treatment options with explanations of the advantages and risks of each. The treatment was carried out under his supervision, and I always understood what was happening next. It was especially important to feel that the doctor was truly monitoring every stage rather than simply prescribing a standard regimen. This greatly reduces anxiety in such a difficult situation. 14/09/2025

Turkey, Istanbul

VKV American Hospital is a private multidisciplinary hospital in Istanbul, part of the Vehbi Koç Foundation. The hospital is JCI-accredited and operates according to American quality standards.

For oncology patients, the MD Anderson Radiation Treatment Center is of central importance. It opened in January 2010 as a result of a partnership with the University of Texas MD Anderson Cancer Center (Houston) — the leader of the “America’s Best Hospitals” ranking among cancer hospitals. The partnership means standardization of treatment practices, protocols, and quality control under the “One Practice Model” framework.

The Department of Radiation Oncology is equipped with new-generation linear accelerators for IMRT (intensity-modulated radiation therapy), stereotactic radiosurgery and SBRT, 4D-CT simulation, and CT-planned brachytherapy.

Under the leadership of Professor Selek, the center treats tumors of the lung, brain, head and neck, gastrointestinal tract, and other solid tumors. Treatment is delivered in a multidisciplinary format — together with medical oncologists, thoracic surgeons, and neurosurgeons.

An International Patient Department is available for foreign patients.
