General SurgerySpecialist

He was born in Trabzon in 1959. He graduated from Istanbul University Cerrahpaşa Faculty of Medicine with honors in 1982. In 1988, he was appointed as the Chief Assistant of Haseki Hospital 1st Surgery Clinic as a General Surgery Specialist. He completed his military service as a General Surgery Specialist at Ankara Etimesgut 600-Bed Air Hospital between 1988 and 1990.

In 1991, he was appointed as the Chief Assistant of the General Surgery Clinic of Okmeydanı Training and Research Hospital. In 1999, he passed the Clinical Chief and Deputy Chief examination organized by the Ministry of Health with the first place. In 2003, he concentrated his studies in the field of Breast and Endocrine Surgery. In 2005, Ductoscopy (milk duct endoscopy) began to be performed for nipple discharge for the first time in Turkey. He has performed over 1500 ductoscopy procedures to date. It is currently the only clinical practitioner of this method in our country.

In 2008, he developed the Endoscopic Papillomectomy method, which provides the non-surgical treatment of "Intraductal Papillomas" that cause nipple discharge, for the first time in the world. To promote the method, Dr. Susan Love was invited to the USA by the Research Foundation as a speaker at the 2009 Intraductal Symposium. She is invited as a speaker to all symposiums after this date.

In 2009, he applied for the YÖK Associate Professorship exam and received the title of Associate Professor of General Surgery in his first year.

In 2011, she was chosen first in the scientific research competition on Breast Cancer held in Los Angeles, USA, and received a 20,000 USD award from the Dr. Susan Love Research Foundation.

He left public service in 2012 and was appointed as a faculty member at Istanbul Yeni Yüzyıl University.
