Bone marrow transplantation
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.

AML M5 (acute myeloid leukemia)
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.
