So what exactly is blood cancer? Our blood flows through blood vessels to supply all tissues in the body with nutrients. In the approximately 5 liters of blood circulating in our body, there are billions of blood cells that carry out various vital functions. All blood cells originate from hematopoietic stem cells. The term "blood cancer" is a general description of various hematopoietic cancers. These include the different types of Leukemia, Lymphoma, Multiple Myeloma, and more.


How can blood cancer patients get a second chance at life? For many blood cancer patients, a blood stem cell donation from an unrelated donor is their only chance of survival. The blood stem cells are collected from the donor and implanted in the recipient – in a stem cell transplantation. The new, healthy blood stem cells help the recipient’s bone marrow to regenerate and produce healthy blood cells again. For this to work, the donor and recipient must have exactly the same HLA markers. You could be the perfect match for a patient somewhere in the world – and help them sometime soon!
