Hematologists in Turkey

I noticed a small lump under my jaw that gradually grew toward my ear and made it almost impossible to breathe. I went to the esteemed Dr. Hakan İsmail. After the diagnosis of lymphoma, my treatment began immediately, and from the very first session, my swelling started to go down. Thanks to Dr. Hakan İsmail’s treatments, I am currently well. My treatment will hopefully conclude with the procedure recommended by him. I am infinitely grateful to my very valuable Dr. Hakan İsmail and his dear assistant Zehra for their constant support, patience, and care throughout my treatment. I am so glad you exist.

After my spouse was diagnosed with lymphoma, we went through a very difficult period. However, Dr. Hakan İsmail Sarı and his team, especially his assistant Zehra, made this process much easier for us. The most important point was their incredibly fast and accurate action during the diagnosis phase, which allowed treatment to begin without delay. My spouse has completed treatment, and our follow-up checks are clear. This entire process was made possible thanks to the doctor’s meticulous approach, knowledge, care, and human touch. They patiently answered all our questions and reassured us at every concern. Professionally and personally, Dr. Hakan İsmail is an excellent physician who made us feel like part of the family. We are deeply grateful for his dedication and kindness.

Dear Dr. Hakan and Zehra, I literally owe my life to you 🙏🏻. Seven months ago, I was diagnosed with Stage 4 lymphoma, and during my treatment and diagnostic process, I was under your care. Thanks to you, I am now completely free of the disease 🥳. I can never repay you. If anyone has this disease or suspects it, this should definitely be your destination. Dr. Hakan and Zehra will change your life, I am sure 😊🙏🏻.

During my stomach cancer journey, I met Hematology specialist Dr. Hakan İsmail, whose knowledge and care provided me great support. Throughout my treatment, he explained every step in detail, patiently answered all my questions, and gave me moral support. I am truly grateful to him. His medical expertise and human approach make him a highly trustworthy doctor. I recommend him to everyone without hesitation.

Our 81-year-old grandfather was diagnosed with chronic lymphocytic leukemia. At the state hospital, the doctor recommended starting chemotherapy and warned about side effects, including infection risks and potential ICU admission. This worried us, so we decided to consult a specialized expert. After research, we found Prof. Dr. Hakan İsmail Sarı and immediately booked an appointment. He carefully reviewed all reports and tests and explained that chemotherapy was not necessary. Instead, smart drug therapy could control the disease. He spent about an hour with us, answering all questions patiently and alleviating our concerns. We were very satisfied with his knowledge and experience. I highly recommend consulting him in similar situations.

29/09/2025

Dr. İsmail has a crucial quality for a doctor: compassion ❤️. His knowledge, skill, and experience are already top-level, but what made my treatment especially unique was his dedicated attention to my needs, approaching me sensitively and carefully. He always made me feel safe and stayed with me late at night when necessary. I am grateful to my precious Dr. İsmail for being by my side during this difficult journey 🙏🏻. Many thanks also to Zehra, Damla, Ayşenur, Dilan, Hatice, Dilşat, and the wonderful supporting team.

17/07/2025

We had just recently met Dr. Hakan, but from the first moment, his explanations, approach to our questions, friendliness, and close attention made us feel very secure. Assistant Zehra was equally supportive regarding communication and procedures. Many thanks for all your support.

04/07/2025

It is difficult to express in words the knowledge, experience, and patient care approach of Dr. Hakan İsmail. We are lucky our paths crossed. Some people leave a mark in life, and Dr. Hakan is one of those special people for us. Special thanks to Zehra for facilitating communication and always providing quick responses and understanding. 🙏

02/06/2025

Dr. Hakan is extremely knowledgeable in his field, keeps up with the latest scientific developments, and can empathize easily with patients. He provided detailed information about my mother’s illness at every stage in a language we could understand. We are grateful for his guidance and support throughout this journey. Special thanks also to the sweet Zehra 😊🙏.

24/05/2025

My dear doctor ♥️. From the start of my journey on September 18, 2024, he never withheld his support, providing excellent treatment that cured me by March 24, 2025. We started lymphoma treatment based on pathological diagnosis, and Dr. Hakan carefully monitored every detail throughout the process. With Zehra and the team, my treatment went smoothly. I am grateful they exist ♥️.

12/05/2025

From the first day of my treatment, Dr. Hakan İsmail carefully managed my diagnosis, follow-up, and treatment, providing detailed information and ensuring a positive outcome. Assistant Zehra’s support allowed me to get help remotely when needed, which was invaluable. He is a highly recommended physician for anyone needing similar treatment. Many thanks to Dr. Hakan and Zehra.

Our professor is not only a highly valuable doctor but also a wonderful person. His care, attention, and support during my father's treatment meant a great deal to us. Thank you for everything, dear Professor.

01/05/2025

Our doctor Omur is not just a physician — he is a role model. With his understanding and cheerful manner, he managed to convince my father to undergo surgery — something no one had been able to do for two years. It seems it isn't always about knowledge, but also about the ability to communicate with the patient! There is no need to mention his intellect, medical skill, and ethics. I wish everyone could meet doctors like him.

01/05/2025

A passionate, caring, dedicated, and incredibly successful hematologist. On top of all these qualities — the most humble doctor you will ever meet. He explains, understands, reassures, and you realize you are in the very best hands. His visits during the bone marrow transplantation process fill you with morale and energy! Thank you, Professor Gokmen!

01/05/2023

Dear teacher, first of all I wish you success in your new hospital. May God protect you from disappointments. May your path be bright. In your profession, conscience has always come first. Your conduct lets one feel like a brother to you. May your dear mentor help you feel at peace. May success, health, and good fortune accompany you.

01/05/2025

May God bless my teacher — he is a deeply respected man. He is excellent in every way.

I visited Medicana Hospital in Beylikduzu, and overall it is a very good clinic — large, well-organized, and professional. Professor Yener, a hematologist, is truly excellent at his work. He is highly competent and carefully monitors the patient's condition step by step. The hospital also has a translation team that works wonderfully, especially Rama, the translator. She does not just translate but also helps, gives advice, and significantly facilitates all procedures within the hospital. She also coordinates appointments with the doctor and other organizational matters, thanks to which the entire process goes very smoothly. Honestly, my communication with the hospital was mostly through her, and she was extremely supportive. The only drawback is the very high prices. Without insurance, it is almost impossible to pay. My advice — get tests done outside the hospital, but follow-up monitoring and consultations are best done at Medicana, because both the doctors and the translation team are truly at a high level. 02/10/2025

Before going to Professor Yener Koc, be sure to get a second, and preferably a third, opinion. 10 years ago, we approached him in Antalya with my father's diagnosis — non-Hodgkin B-cell lymphoma. Without any consideration, he immediately said that my father's stomach had to be removed and scheduled the surgery date. The next day, we consulted another hematology professor, who explained that this was a medically very incorrect and dangerous approach, that for such lymphomas, removing the stomach directly puts the patient at risk, and that the proper treatment is chemotherapy. My father underwent treatment based on the second opinion and recovered completely after about a year. Had we followed the first advice, it is unknown whether he would still be alive today. Even if he had survived, he would have had to live without a stomach and on a large amount of medication. This experience showed us that even if a doctor holds the title of "professor," it does not mean that every decision he makes is correct. Especially in matters of life and death, one cannot rely on the opinion of a single specialist — it is essential to consult other doctors. It is also worth searching for previously published, but now removed from the internet, information about unsuccessful bone marrow transplant cases involving this doctor. 27/01/2026

We turned to Professor Yener Koc for treatment of my father. The doctor immediately performed a thorough diagnosis, explained the therapy plan in detail, and accompanied us at every stage. Thanks to a properly selected treatment and attentive monitoring, we managed to achieve stable remission. Very grateful for the professionalism and support. 14/06/2025

I underwent treatment with Professor Yener Koc at Medicana Clinic. I was very satisfied with the level of medical care: the doctor closely monitors the patient's condition, adjusts treatment, and is always available. I would also like to note the well-coordinated work of the team and the convenient organization of the process for international patients. 09/03/2025

Professor Yener Koc made the impression of an experienced and attentive specialist. During the consultation, he explained everything in simple and clear language, proposed an effective treatment plan, and supervised every stage of therapy. The doctor's confidence and individualized approach were felt, which helped me go through treatment calmly. 27/01/2025

In April 2020, my mother was diagnosed with AML. Thanks to Dr. Burak, we are seeing positive progress every day. He is always there for his patients, both medically and socially. We are very grateful for his support.

08/06/2020

I referred to him in 2022 due to prolonged fatigue and weakness. I only saw him for a total of 3 minutes. After routine blood work and checking ferritin levels, he said there was no problem and sent me away. My complaints still continue to this day.

18/03/2022

We have been treating my father with Dr. Burak for a month now for his MDS. All the necessary tests have been done and he has been prescribed blood and iron transfusions. Now my father's condition has improved significantly. Thank you very much for your attention and friendliness.

In August 2018, I made an appointment for weight loss, elevated ESR and other symptoms. The first visit went well and the necessary tests were scheduled. When the results came back, he recommended a follow-up visit, which I made an appointment for. However, despite my desire to discuss the results in person, I was asked to show the results to his secretary first. I insisted on the appointment and was still admitted and scheduled for a biopsy. Everything went fine. Three days later, I came in with a quick question that would only take 10 seconds. I called to make an appointment for a follow-up appointment, but there were no spots available. When I got to the clinic, I wasn't even admitted for the short question. I explained that I was also a doctor and wanted to ask the question directly. However, there were complications and I was extremely dissatisfied. I do not recommend him from either a professional or deontological point of view.

Serdar Bediy became my savior. I have had lymphoma for 3 years now. He is a specialist in chemotherapy for lymphoma and bone marrow transplantation. I had no money for the vaunted Germany. But even in Russia, I did not want to treat cancer. I chose a clinic in Turkey with a coordinator. I was treated in Emsey. The treatment is difficult, the transplant was expensive, but the main result is that the lymphoma has receded. Analysis is clean. How can I not be happy here. Many thanks to Dr. Serdar and of course to all the nurses and staff. Simply the best hospital ever!

Dr. Serdar is an excellent hematologist. I have leukemia and it was decided to take my bone marrow in order to transplant it after chemotherapy. The treatment went well. Yes, not without side effects, but it always happens with chemo. I am grateful to the Emsey clinic. The best doctors work here!

I have had lymphoma for 4 years now. 2 months ago I had an appointment with Dr. Serdar Bedii Omay, who suggested that I should undergo Chemotherapy. After taking Chemotherapy, my condition improved a lot, and the friendly and sincere attitude of the doctor gave me great confidence.

I have a blood clotting disease, a gene mutation. I went to Dr. Serdar several times during my pregnancy and just recently, this week. He is a very humane doctor, explains everything in essence and calmly, without haste. I am satisfied with his consultations, I always get clear answers to all questions.

I had problems with blood clotting, helped by Dr. Serdar Bedii Omay from Emsey.

After visiting several doctors, we went to Prof. Turker Çetin on recommendation. He carefully and attentively followed every step of my wife's treatment, from start to finish. He is truly an outstanding doctor. Many thanks to Prof. Turker Çetin. If you are looking for a reliable doctor you can trust with your life, I recommend Turker Çetin.

Prof. Turker Çetin's name was recommended to us by a doctor from an American hospital. She said that he is the best bone marrow transplant specialist in the world. Other doctors in America also confirmed that Prof. Çetin is one of the best in this field. We entrusted him with the treatment of my cousin and he made a full recovery, although many other doctors gave no hope. Prof. Çetin was the Head of the Department of Hematology at GATA when he treated my brother. He now works at Ankara Memorial Hospital. Prof. Çetin has completely cured my brother. May God bless him.

While researching my husband's leukemia treatment, we learned that Professor Turker Çetin is one of the most qualified hematology and bone marrow transplant specialists in Turkey. Although many doctors said there was no hope, some recommended that we go to Prof. Çetin. He gave us hope and completely cured my husband of leukemia. Prof. Çetin is an outstanding doctor and a wonderful person. We the whole family express our gratitude and respect to him.

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.

Prof. Turker Çetin is a very successful, knowledgeable, hardworking and disciplined doctor. He values his patients and is a kind and caring person. May God prolong his life. He treats a lot of patients.

In April 2010, we met Prof. Turker Çetin. When I found out about my diagnosis, I lived every day as if it were my last. But Prof. Çetin assured me that everything would be fine, and that gave me strength. It is now the end of 2012 and I am continuing chemotherapy, hoping for the best. He is a very attentive, disciplined and kind-hearted person. I trust him with everything. Thank you for being you, good man. May God keep you safe.

I am extremely grateful to Dr. Zafer and his team, to every employee the hospital is 5 stars.

On October 29, 2020 we came to your hospital for stem cell transplantation for my wife. Limitless thanks to Prof. Zafer Gulbaş, Dr. Çiğdem Hanim, Dr. Damlanur Hanim, all nurses and support staff who helped us, we were very satisfied with your hospital, thank you.

This hospital is wonderful. Thank you, Professor Zafer Gulbas, from the very beginning you gave us hope that everything would be fine, and it is. The treatment is going very well, we have a little more to go and we will go home healthy. My opinion is that it meets the highest level of medical standards. The staff is very competent, caring, friendly and supportive. The conditions are very good.

My son had a bone marrow transplant 2 years ago and I want to thank our Dr. Zafer and his team endlessly. I wish you to always have a smile on your face and be patient. They always listened to us and when Dr. Zafer came to the room, it was like he shared his energy and it gave us strength. Anadolu is like a five star hotel, we are very, very satisfied, the fees they receive are halal all the way through.

My wife Nihat Osmanoglu had a bone marrow transplant, the doctors and nurses in the transplantation department are wonderful. Thank you very much to our professor Zafer and his team, you are all wonderful, we are very happy, you are all wingless angels.

My father had a bone marrow transplant and all the doctors and staff, especially Dr. Zafer, are true professionals. When my father goes for every checkup, we forget that he is sick, thanks to the extremely positive energy of the doctors.

Neurologist Yashar and hematologist Zafer are still the best doctors in terms of explaining problems in detail, calming the patient down and making them feel better. I haven't been there for a long time, but when I was last there I noticed that the quality of services has decreased. The staff is indifferent, most of the doctors are gloomy, and the patient is not trusted.

I was diagnosed with leukemia and my cousin recommended me to see Dr. Fatma Deniz Sargan. I made an appointment with her at Medipol Clinic. She prescribed chemotherapy for my treatment. After treatment under her guidance, the disease receded. I feel good now and I am very glad that I met such a good medical specialist in time. Thanks.

13/01/2021

With a diagnosis of Lymphoma, I went to Dr. Fatma Deniz. After undergoing the bone marrow transplant she prescribed, I am completely healthy. My brother turned out to be a suitable donor. I thank the doctor and my family for their support. I recommend Fatma to anyone who needs medical help.

13/02/2021

After my myeloma was detected, my doctor recommended me to see Prof. Fatma Deniz. She is very competent and provides effective treatment for hematologic diseases. I came for a consultation with her at Medipol Clinic and she reviewed my tests and diagnostic report. After a complete analysis of my data and consultation, she scheduled me for a bone marrow transplant. К Fortunately, we found a donor among my relatives and my transplant was successful. Since then, I have been living a healthy life.

02/03/2021

I recommend Dr. Fatma Deniz. Please contact her and you will not regret it. She helped my son beat leukemia. We are very grateful. She is a very competent doctor, explains everything clearly. And most importantly, the result of treatment is good. We were treated at Medipol clinic.

06/07/2022

In 2006, we met Professor Mutlu Arat at the hematology department of Ankara University because of my illness. He is a doctor with exceptional human qualities and high professionalism. He performed my bone marrow transplantation, for which I am immensely grateful. I wish him good health and a long life.

21/01/2021

My brother was diagnosed with AML M5 in 2007 and was treated by Professor Mutlu Arat. The doctor was very attentive and caring, always treating his patients with great empathy. Despite the tragic outcome due to complications of the procedure, we always remember his humanity and involvement — even in that difficult moment, he did not leave the family without support.

15/10/2015

In 2000, I underwent a bone marrow transplantation. Thanks to Professor Mutlu Arat, today I live a full life: I have a family and a child, and I am healthy. I am endlessly grateful to him for his work and professionalism.

05/03/2014

Words cannot describe my gratitude to Professor Mutlu Arat. My current health is the result of his work and care. He will forever remain in my prayers as the man who gave me life.

16/02/2014

Professor Mutlu Arat is one of the best doctors I have ever met. During my aunt's illness, he showed incredible professionalism and humanity, helping not only with treatment but also with moral support. His knowledge and experience are truly impressive.

28/01/2014

A very attentive and kind doctor. He helps patients feel better both morally and physically, always supporting them and instilling confidence. We are very grateful to him for the treatment.

03/05/2013

I underwent a bone marrow transplantation in 2000. Thanks to Professor Mutlu Arat, I have been alive and healthy for many years. I am endlessly grateful to him for everything he has done for me and other patients.

14/04/2013

Opinions vary: some consider him an outstanding specialist with vast experience and humanity, while others note his complex character. But professionally, he is recognized as one of the strongest hematologists, who achieves excellent results in treating patients.

10/11/2012

Our family has known Dr. Gulyuz since 2013. Then we visited her at the Medical Park clinic for a bone marrow transplant. A couple of years ago, we also had a consultation at the Acibadem medical center, as my son had changes in his tests. She prescribed medication and everything went back to normal.

During the examination, the professor found symptoms of another illness in my child (son was 18 months old at the time) and referred us to the appropriate specialist. Early diagnosis made it possible to achieve a good prognosis for our boy. If Dr. Gulyuz Ozturk hadn't noticed bad results in the tests, it might have been too late in a few months! I thank her wholeheartedly.

This is our precious doctor who gave my son a bone marrow transplant. She is like an angel, always kind and reassuring in all matters, cheers us up when we lose hope. We are grateful...

I was a patient of Gulyuz Ozturk, I had a bone marrow transplant. She tried very hard and empathized, supported. God bless her, I will never forget her.

Due to severe anemia in my 1.5-year-old son, we turned to a pediatric hematologist referred by our pediatrician. We arranged a meeting with Professor Gulyuz Ozturk and examined our son. The examination was very informative, we were diagnosed. Our disease is hereditary spherocytosis. Gulyuz herself is very friendly and sincere. We are very grateful to her. It's good that there are such people.
