Understanding and Diagnosing Polycythemia Vera (PV)
This animation helps you understand polycythemia vera (PV), a type of myeloproliferative neoplasm (MPN) in which the bone marrow produces too many red blood cells. You'll learn how blood cells are made and why having too many red blood cells can thicken the blood, increasing the risk of clots (which can cause heart attacks, strokes, or leg blockages), bleeding problems, and an enlarged spleen. The animation also covers key signs and symptoms, the role of the
JAK2 mutation, blood tests, bone marrow biopsy, and steps you can take after diagnosis.
