Oncologists abroad

I came here in the spring of 2022 with a diagnosis of stage 4 adenocarcinoma. The organization of the treatment process was handled by the head of the International Department, Lala. The organization was at the highest level. I was admitted to the hospital immediately and started treatment without delay, as the malignant process was progressing. I received modern diagnostics, treatment - chemotherapy and radiotherapy. The disease receded. A PET CT scan 7 months after treatment showed a complete absence of tumor activity. Modern medical and diagnostic equipment, quality medicines, professionalism - this is about Istanbul University Hastanesi Liv Hospital in Istanbul. Special thanks to oncologist Tahsin (Uzm. Dr. Tahsin Özatlı), radiologist Taylan (Uzm. Dr. Taylan Bükülmez) and his staff Irmak and Melisa. Also, special thanks to Imran Fiyruzoğlu, an employee of the clinic's International Department, guide and translator, a graduate of Kharkiv Medical University. This hospital gives you a chance and an opportunity to live!

Doctors at Liv Hospital: I would like to thank my wonderful doctors, Mr. Tahsin and Ms. Duygu. Thank you for everything. I wish you good health and long life. Thank you very much. The staff: Lale, Tuba, Jan, Imran and others, to each of them I am very grateful, and most importantly I wish you good health.

Through God's grace and generosity, I was treated by Tahsin Ozatli, an oncologist, and I am very grateful for my communication with him. The intermediary between us was the translator Hussein Al-Salih and he was very helpful. With gratitude.

I would like to thank the oncologists Faruk, Tahsin and his team in the chemotherapy service, the nurses Sevim, Deniz, Eche, Meltem Hanim - in the reception area, in short, everyone.

My mother was treated at your hospital. We were very pleased with our chemotherapy doctor, Tahsin, and our nurses, Deniz and Sevim, who conducted our treatment. We are very grateful to all of them.

After my mother was diagnosed with breast cancer, we met our doctor, Erkan. My mother’s condition had advanced due to it being hidden from us, and she had a large external wound on her chest wall. Dr. Erkan quickly devised a treatment plan, emphasizing that we couldn’t lose a single day, and immediately started her on medication. His goal was to shrink the wound to chest wall level and prepare her for surgery. He arranged all the necessary tests: PET scan, brain MRI, contrast biopsy, and blood tests.

We started treatment with 4 courses of chemotherapy and targeted therapy. The results were incredible: the wound visibly reduced with each course and eventually disappeared. Seeing such positive progress, the doctor added two more courses and applied to the Ministry of Health for drug approval. Today, my mother completed her sixth chemotherapy session, and follow-up PET and brain MRI scans showed no metastases. The external wound on the chest wall is gone, and the internal part has significantly reduced. We are now ready for surgery, and after that, we will continue treatment with Dr. Erkan.

Dr. Erkan has been the greatest blessing for us during this journey. His positive attitude, detailed explanations, and excellent communication with both the patient and the family have been invaluable. Words cannot express our gratitude. He works with an outstanding team of chemotherapy specialists and assistants whose positive approach fills us with trust and hope.

Dr. Erkan, may God protect you and guide you on your professional path. We wish you success and look forward to meeting again in better days.

We have been walking this journey together for about 13 months, treating my father’s stage 4 lung cancer with metastases, and thanks to our dear Dr. Erkan, we achieved amazing results. We entered the door in a wheelchair and walked out on our feet. Endless gratitude for his great success in his profession and his dedicated approach to patients. We are so fortunate to have crossed paths with you! Words are not enough to express our thanks.

An amazing doctor, a kind person. Patients trust him greatly because he is sincere and honest. Wishing you all the best, doctor. Respectfully!

I feel obliged to thank Dr. Erkan Kayıkçıoğlu and all the staff of the oncology department at Liv Hospital Istinye Bahçeşehir for their role in my mother's recovery. Meeting such an experienced and knowledgeable doctor as Dr. Erkan is a great fortune. May God bless him!

27/08/2024

Throughout every stage of my treatment, which included 4 courses of chemotherapy, the detailed explanations and quick responses from Dr. Erkan Kayıkçıoğlu and his team were a tremendous support to us. I am endlessly grateful to Dr. Erkan and his team!

21/08/2024

In May 2019, when I was first diagnosed, I was in shock. I had heard about people with similar illnesses, but experiencing it yourself is a completely different feeling. When Dr. Erkan examined me, my fears up to that moment seemed to vanish. He spoke so encouragingly that I felt almost cured even before starting the treatment. At a time when I thought my life was coming to an end, I suddenly felt that I still had many years ahead.

He was incredibly attentive, carefully addressing every detail of my condition. He explained the treatment process in great detail, and when I started therapy, I knew exactly what to expect at each stage. In just six months, he completely cured me. The correct diagnosis, effective treatment methods, and, most importantly, his immense moral support were the keys to my recovery.

Even after my treatment was completed, we became almost like brothers. If I missed follow-ups, he would always remind me and stand by me. I am forever grateful to my doctor and friend, Erkan Kayıkçıoğlu, for saving my life and for the time he gave me. Thank you so much for everything you’ve done for me.

11/04/2024

My mother has cancer and she is this doctor's patient now she is almost okay just today did her 13th chemotherapy session.

Here I say THANK YOU to you sir wish you all the best!

15/03/2020

I was admitted to the hospital with thyroid cancer. From the beginning of the process, my wonderful doctor Ebru Esen calmed and encouraged me with her smile and support. I also thank Sena, Furkan, Lale, and dear Hüseyin for their help. Thanks to you, today I am leaving home healthier and without any complications. May God bless you all.

15/02/2024

I had an examination in the general surgery department. Every time I came, my doctor Ebru took great care of me. I also want to thank assistants Damla Karatan and Büşra Kurtbey for their attention.

15/08/2023

I reached out to Dr. Ebru through her institution. I was diagnosed with rectal cancer, and the treatment is ongoing. I am very pleased with my doctor. She explains everything clearly, is attentive, and highly knowledgeable. I would recommend her to my relatives.

20/12/2023

I am very satisfied with the professionalism of the doctor, her patient care, and respect for her profession. I visited due to a tumor and underwent surgery. We thoroughly discussed everything before and after the operation. I recommend her as one of the best doctors in this field.

10/07/2023

I underwent a colonoscopy and endoscopy. The doctor provided detailed information, and I am very satisfied. She explains everything in an understandable way, leaving no questions or doubts. A very attentive and kind doctor. I recommend her to all patients and hope that there will be more specialists like her.

05/07/2023

We thank PROF. DR. SEZER SAĞLAM and Duygu Özbay for their attentive attitude and care. The entire process and the upcoming procedure were explained to us in detail.

18/07/2025

Thank you to my doctor Sezer Saglam. I also thank Mrs. Duygu for her attention and care.

11/07/2025

Our journey with this wonderful, attentive and kind doctor began at the Çapa Faculty of Medicine and continued at the Tansan Oncology Center. My wife, unfortunately, had stomach cancer at the last stage. Sadly, she could not be saved, but thanks to our doctor this difficult period passed with as much dignity as possible. He did not leave us without attention until the very last moment, and thanks to his care her final days passed without pain. Thank you, Mr. Sezer.

25/03/2020

He is an attentive, knowledgeable, kind doctor who perfectly understands the patient’s psychology, constantly engages in research and is very hardworking. He truly deserves the title of a real scientist. The fact that our treatment is now going successfully we largely owe to his assessment and recommendations. We hope to overcome this period thanks to his support. Many thanks to him.

08/04/2014

Mr. Sezer is a calm doctor who keeps up with modern medical literature and provides the patient with all the necessary information in a reasonable amount. He works at Gayrettepe Florence Nightingale. The treatment and examination capabilities at this clinic are also at a very good level.

24/03/2014

Excellent.

25/08/2011

At the moment when our hope had almost faded, Almighty Allah sent us this wonderful man — Professor Koray Acarli. I prayed: "God, will I ever be able to sit at the same table and eat together with my child?" Allah made him precisely the means by which these prayers were answered.

Dear doctor, we will never forget you throughout our entire lives. Now Poyraz and I are living our happiest days thanks to you. May Allah grant you a long life. Paradise has eight gates — may the Lord grant you the right to enter through any of them you wish.

You are a wonderful person. No matter how much we thank you and your team, it will never be enough. We love you.

14/08/2025

Doctor, you and your team are such wonderful people that it cannot be expressed in words. May the Almighty be pleased with you and your team.

You have given the joy of life to many families just like ours. With the deepest respect, I express my gratitude to you.

Greetings from Eskişehir.

In October 2015 I was hospitalized at the Çapa Faculty of Medicine with a diagnosis of "liver cancer." After a year of anticancer treatment I was ready for transplantation, but at Çapa they kept delaying the operation because the risk of a fatal outcome was high. This continued until we found our Koray hodja. Koray hodja told me: "Since you are a complex case, no one will easily take on your transplant. We take the risk," — and gave me the green light. My donor was also ready, and as a result of a long (13.5-hour) operation, after which our hodja told my relatives, "This is the first time I have performed such a transplant," on November 22, 2016 I returned to life. I was discharged after 8 days in intensive care and 29 days in the ward. Follow-up continues. I am endlessly grateful to our hodja Koray bey and the entire transplantation department team.

28/02/2020

I underwent a liver transplant at Memorial Şişli Hospital on October 10, 2012. May Allah be pleased with you all. Now I am very healthy, my liver is in excellent condition. Later a problem arose with my spleen — it was also removed. Apparently this is how Allah wrote it in my fate — I stayed in the hospital longer than anyone. Everyone was discharged on day 7, and I exactly on day 40. I caused the nurses and orderlies many difficult moments — I ask everyone for forgiveness. Great thanks to everyone, to the entire organ transplantation team, above all to Professor Dr. Münci Kalayoğlu, Professor Dr. Koray Acarli, associate professor Dr. Turan Kanmaz who was constantly by our side, operator Dr. Yücel Yankol, operator Dr. Nesimi Mecit. To my doctors, to the blood bank staff who sent blood when I needed it, to the general intensive care staff who fulfilled all my requests, to the angels of the hospital — our nurses and orderlies who came running for our every need, to the cafeteria and café staff who never left me without food, and to the security guards who ensured our peace — thank you.

22/12/2012

In 2009 I was diagnosed and treated at many hospitals. The doctors at these hospitals said that I would not survive a transplant. The last time I lay in the hospital for 40 days, and my condition worsened even more. Then, after meeting Münci hodja and Koray hodja, I gained hope that I would recover. Based on the results of our hodjas’ examinations they said a transplant was possible, and on February 23, 2012 a transplant was performed from my twin. Now I have returned to health and am very happy. I am doing well, praise Allah. Enormous gratitude to the doctors who performed the operation — above all to the esteemed Professor Dr. Münci Kalayoğlu and the esteemed Professor Dr. Koray Acarli, the entire organ transplantation team, the coordinators Nilgün hanım and Altan bey, the nurses on the 7th floor of building B, and all the staff — for their attention and professional attitude toward their work.

23/03/2012

On October 1, 2007 you gave me life again. Dear Münci Kalayoğlu, Koray Acarli, Yücel Yankol, and all the Memorial staff who put in their effort — on March 14, 2012, on the occasion of World Medicine Day, I once again express my gratitude. You gave me life again. For exactly 4.5 years now I have been living without any problems. Thank you. May all happiness be yours.

14/03/2012

Dear Professor, with respect and love. When I first came to you after learning about my illness, I was 22 years old. Many doctors had decided to remove my breast due to the tumors, but, contrary to their diagnoses, your words gave me new hope. The fact that you operated on me the very next day and promised me a beautiful life, along with the psychological support you provided, helped me embrace life again. I wish everyone could be as fortunate as I am. Infinite thanks for everything you gave me and my life.

Thank God for Professor Vahit. The day after I was diagnosed with breast cancer, another hospital was preparing me for a mastectomy. When we contacted him through WhatsApp to ask about the biopsy results, despite his busy schedule, he called us back and said "First, she needs medication, then surgery," thus saving us from a terrible mistake. He is truly a remarkable person. As my oncologist said, Vahit Ozmen saved you from the edge of disaster. I will pray for you all my life, Professor. Thank you so much for being there. May God protect you.

The professor performed a very difficult and demanding operation flawlessly — "like poetry." At every follow-up visit, he showed immense attention, explained everything in detail, and left no question unanswered. Thank you, Professor.

In my relationship with the doctor, his expertise, knowledge, communication, and the confidence he inspired were very important to me. Vahit Bey fully met my expectations. Moreover, I can freely reach out to him whenever necessary and always receive a response. Thanks to him, I have regained my health.

The professor's success in treating breast cancer and his patients is always the talk of the hospital. At the hospital where I work, I encounter women almost every day in different areas asking where to find this doctor. In addition to his medical work, he has built two public educational institutions — an elementary and a middle school — in his hometown of Muş, using his own funds. One of the rare people in Turkey who truly does their job properly.

On March 9 I had surgery to remove my uterus. It is only the third day after the operation, but everything went very successfully. Many thanks to the doctor. Very glad that I turned to him on recommendation.

14/03/2026

Very happy that I met such a doctor. For several years I was monitored for uterine fibroids. Over time, severe pain and bleeding outside the cycle appeared. Before that, I had consulted several doctors who told me that fibroids 8.5–9 cm in size could only be removed by open surgery.
The doctor offered a closed method without incisions and punctures. Already the next day I was able to get back on my feet. Later, after the pathology results, I also had ovarian surgery using the same method, and the recovery was again very quick. Now I feel good and am endlessly grateful for such attentive and modern treatment.

11/09/2025

I came in for a follow-up consultation. After studying the test results, the doctor said that getting pregnant would be practically impossible due to PCOS, and then clarified that it is not impossible, just more difficult compared to other women.
I believed those words and stopped using contraception just once. While waiting for my period, I found out that I was already 7 weeks pregnant. I am still happy about this now, but after the consultation I was left without a sense of confidence and trust.

12/09/2025

I want to share the treatment story of my 64-year-old mother. Over the years she has had about ten abdominal operations, including hernia operations and the placement of a large mesh. After the diagnosis of "uterine cancer", in different clinics they only talked about open surgery with high risks.
Only this doctor offered the modern V-NOTES method. As a result, instead of a difficult open operation, the affected area was removed in a minimally invasive way, and already the next day she walked on her own and felt well. Despite the fear due to the large number of past operations, the doctor with his attitude and professionalism helped to go through this period much more calmly.

28/03/2025

He is one of the most competent specialists in the field of gynecological oncology. Despite the complexity of the operations, the doctor confidently handles even severe cases thanks to his experience and knowledge.
Very attentive, punctual and always answers questions in detail. I had a complex hysterectomy, and the recovery was as easy as possible and without severe pain. I fully entrusted him with my health and can sincerely recommend him.

14/12/2022

Professor Mustafa Ozdogan is an expert in his profession and is highly regarded by patients due to the two-way communication he establishes, as well as the way he ensures that his patients respond to early treatment, as well as the moral support he gives. Despite being tired during the day, he still answers all questions and takes care of his patients. I would like to thank him and his entire team. I wish you continued success.

I turned to Mustafa Ozdogan about my father’s illness. Unfortunately, it was already too late, and he chose his words in such a way when informing us about this that it did not cause us any moral harm. He is not only a good doctor, he understands human relationships. So thank you, even if we couldn't find a cure.

Mustafa Ozdogan is a highly professional and very friendly person whom I would like to call my friend. He gave me answers when there were none and saved my life. I highly recommend him and his team.

Endless gratitude to our most valuable doctor, whom we met at the worst time of our lives, but who gave hope to my father and supported him even in those difficult times.

First of all, Professor Mustafa Ozdogan, God bless you. It is very rare to find a doctor like you. My father lives thanks to you, if you had not helped us, he might no longer be in this world. May God grant you long life.

This is the angel whom God sent to us just when we had already given up hope on everything because of my father’s illness... From our first meeting, with his positive attitude and warm welcome, he healed my father morally, and then helped him recover physically . My father has been in remission for 2 years. Thank you very much for your work. You are saving lives. May God give you long life and good health.

My dear doctor... your approach, your attitude and most importantly your friendliness during my illness played a big role in my recovery. You helped me easily overcome this disease. We love you very much.

Had surgery with a doctor I had absolute confidence in and the surgery was a success. He is excellent at keeping the patient informed, monitoring the condition and being incredibly attentive. The confidence in his expertise in breast surgery is very reassuring. I am glad that my doctor is Mr. Fatih Aydogan.

04/02/2021

People who have not experienced breast disease cannot realize how difficult it is. I put it off for a long time, but finally found Dr. Fatih when it was no longer possible to ignore the problem. He is an excellent surgeon who performed my surgery with meticulous care. Everything went even better than I expected. Thank you for everything.

16/11/2020

Turned to him for surgery after breast cancer treatment. This is a doctor who has left a mark in my life. He thinks of his patients even more than they do and does not put material gain first. I feel blessed to have met him through my illness. Thank you for everything.

27/08/2018

Dear Prof. Fatih Aydogan, I have heard about your achievements in the field of breast surgery. I am grateful for the surgery you performed on my mom and for your attention and humanity afterwards. Thank you so much.

03/12/2016

Dr. Fatih was always supportive in my difficult treatment with his medical knowledge and human qualities. Thank you very much.

24/11/2022

Choosing the right doctor is very important and I realized this when I found Dr. Fatih. Unfortunately, the previous doctor did not do the necessary biopsy and I went through an extra 15 days of stress. Dr. Fatih lovingly does his job, answering all of our questions with care. I am very grateful to him for his professionalism and kindness. After all the necessary investigations, he successfully performed my surgery.

19/08/2022

He treated my mom and we are very satisfied. Always explains things to patients simply and clearly. We thank him for his care.

26/07/2022

I would like to thank Dr. Fatih Aydogan for his care in treating my illness. Thanks to Allah I met such a doctor. Thank you for his qualified help, responsible approach and friendly attitude. He is a very attentive and knowledgeable doctor.

02/02/2022

Meeting Dr. Fatih is my great luck. He is a wonderful surgeon who understands patient's psychology and answers all my questions. My surgery was successful and I am grateful to him and his team.

21/01/2022

One of the best and kindest doctors we have ever met. He professionally performed my mom's surgery for breast cancer. He was always in touch and counseled us before and after the surgery. We are thankful to Allah for meeting such a doctor.

28/04/2021

My sister's doctor. He is a very humble, attentive and knowledgeable doctor. Easy to answer all questions and very helpful. We are very satisfied and recommend him to everyone.
