LÖSEV – The Name of Hope in the Fight Against Leukemia and Cancer
Our Purpose
The purpose of establishing LÖSEV (The Foundation for Children with Leukemia) is to support children with leukemia and blood disorders by meeting all their essential needs — primarily in healthcare and education — and to found and operate national institutions for treatment, education, and research on hereditary and acquired blood diseases.
Each year, around 2,000 new cases of childhood leukemia are diagnosed in Türkiye. For families with limited financial means, this often leads to impossible choices — between the needs of their sick child and their other children.
For this reason, every initiative of our foundation not only aims to raise funds but also seeks to increase public awareness about leukemia, share the struggles of children and their families with society, and promote compassion, understanding, and social responsibility throughout the community.
About Us
From One Table and One Chair to the Hearts of Millions
Established in 1998, LÖSEV – The Foundation for Children with Leukemia – began its journey with a single mission: to transform the lives of children fighting leukemia and blood disorders.
What started with one table and one chair has grown into a nationwide movement of compassion, solidarity, and hope, touching the lives of thousands of children and their families across Türkiye.
At that time, leukemia was widely misunderstood. Many believed it was contagious, and as a result, children and their parents were socially excluded and stigmatized.
Treatment was difficult, expensive, and often inaccessible. Due to financial hardship and prejudice, many children were tragically left behind with the belief that “nothing could be done.”
Driven by determination and compassion, Dr. Üstün Ezer, the founder of LÖSEV, refused to accept this reality. His vision changed the course of leukemia treatment in Türkiye.
Through LÖSEV’s comprehensive approach, children’s medical, educational, and social needs were addressed together — laying the foundation for a holistic model of care that integrates health, education, and community empowerment.
Today, LÖSEV stands as a symbol of love, kindness, and hope — not only fighting cancer but rebuilding lives.
It is a humanitarian organization that ensures no child is left behind due to illness or poverty, offering equal access to care, education, and dignity.
The story written by LÖSEV, grounded in compassion and human solidarity, continues to inspire people around the world and lead the fight against leukemia — for a future where every child has the right to live, learn, and hope.
Our Mission
At LÖSEV, our mission is to improve the quality of life for children with leukemia and cancer, to give them hope, and to stand by their side in every field — from healthcare and education to psychological and social support.
Our goal is to ensure that no child’s treatment is interrupted due to financial hardship.
We work to provide equal access to care, education, and emotional well-being, so every child can heal, learn, and dream again.
Our Vision
Our vision is to make LÖSEV a leading institution in Türkiye and the world in the fight against leukemia and cancer.
Through initiatives such as the Cancer Research Institute and LÖSEV University, we aim to advance scientific innovation, education, and leadership development — building a future where leukemia and cancer are no longer a threat to life.
We envision a world where science, compassion, and equality come together to ensure every child has the right to live a healthy, hopeful life.
