Oncology is the medical field concerned with the diagnosis and treatment of cancer. Chemotherapy, radiotherapy, targeted drug therapies, and oncological surgery are applied with a multidisciplinary approach tailored to each patient. Comprehensive oncology centers in Turkey are equipped with advanced imaging and radiation therapy technologies; the entire process from diagnosis to treatment is carried out in the same center without delay. These services, provided under the guidance of experienced oncologists, are offered with full support to patients and their families at much more affordable costs compared to many other countries.
