Prof. Turker Çetin is an extremely knowledgeable, intelligent, kind and honest doctor who is always sympathetic to patients and their families. My husband, who had leukemia, made a full recovery thanks to Prof. Çetin's treatment, although other doctors gave no hope. We went to him on the recommendation of friends and other doctors, and we have not regretted it. Prof. Çetin completely cured my husband. I will always recommend him as an outstanding doctor.
