A young, rosy-cheeked girl with long, blond hair held back on one side by a blue barrette squints at the camera and smiles. An older woman crouched next to her wearing a blue polo shirt kisses her on the cheek.

Help people with blood cancers or disorders get a life-saving transplant

why you matter

Every minute counts

Every 3-4 minutes, someone in the U.S. is diagnosed with a blood cancer. Many of those people may need a blood stem cell transplant (sometimes called a bone marrow transplant). A transplant can cure or treat 75-plus diseases, including blood cancers such as leukemia and other blood disorders, like sickle cell.

With 75% unable to find a suitable donor in their family, the NMDP RegistrySM is their vital link to the world's most diverse pool of potential matches, including people like you.

At NMDPSM, we do more than match patients with donors. We also support them through transplant—physically, emotionally and financially—and conduct research to improve patient outcomes.

mission in action

Support patients like Warren

Warren is sharing his story to help more patients find the blood stem cell donors they need. Because patients are more likely to match with someone who shares their ancestry, more Asian donors are urgently needed to help build a more diverse registry and save more lives.
