Two brothers from Jastrzębia-Zdrój donated stem cells: each to a different person

Agnieszka Bąk from Jastrzębia-Zdrój fell ill with acute myeloid leukemia. Her younger son Jakub (25) donated her stem cells and helped her recover. Two years later, his older brother Mikołaj (33) made a similar gesture for a complete stranger from Hungary, becoming a bone marrow donor for an unknown patient.
