The Community of Madrid has strengthened its healthcare system by exceeding 75,000 bone marrow donors. This achievement is vital for patients suffering from hematological diseases such as leukemia, lymphoma, or multiple myeloma. The region closed 2025 by surpassing the annual target set by the National Bone Marrow Plan by 2%, driven by an increase in young donors, who are considered the most suitable profile for this therapeutic procedure.

Throughout 2025, the regional Transfusion Center registered a total of 4,719 new donors. Of these, 1,404 registered directly at hospitals, while 688 did so through the Virtual DaMO Plan. The Médula Tour initiative also played a crucial role, attracting 1,700 people, particularly from universities, companies, educational centers, and the State Security Forces and Corps.

This momentum has continued into 2026, with 1,632 new donors added to the registry in the first three months of the year. This figure represents 42% of the annual forecast, demonstrating an accelerated pace in donor availability for transplants. In 2025, the regional Transfusion Center processed 173 transplant requests.

To become a bone marrow donor, individuals must be between 18 and 40 years old and weigh more than 50 kilograms. A small blood sample is sufficient to analyze the human leukocyte antigen (HLA) genetic profile, which helps determine future compatibilities with potential recipients.
