ABOUT US

Onko was founded in Ankara in 1990 by medical oncologist Prof Dr Önder Berk, radiation oncologists Dr. Zeki Güran, Dr. Emin Kamgözen and Dr. Cemil Kuşoğlu.

Its first branch was established in Antalya in 1994 as the first radiotherapy center of the region and served for 18 years.

Istanbul Onko started to serve as the first private center on the Anatolian side and the second private center of Istanbul in 1996. In 2003, it moved to the European side and continued to serve.

Since 2018, the operation of the radiation oncology department of the Koru Hospitals in Ankara has also started to be carried out by ONKO.

More than 45,000 patients were treated in our centers until 2020, when we celebrate the 30th anniversary of its establishment. Many physicians and medical personnel, who have been trained and experienced in our clinics for years, still provide health services in various regions of Turkey and abroad.
