Blast Cells and Myeloblasts: Acute Myelogenous Leukemia
WEBJun 27, 2024 · When someone with leukemia enters the blast phase, abnormal immature white blood cells (blasts) multiply and fill the bone marrow, preventing the production of red blood cells and platelets. Blast cells are also present in the bloodstream and the leukemia cells may have already spread to other organs.
