polycythemia vera


<b>pah</b>-lee-sy-<b>THEME</b>-e-uh <b>vair</b>-uh


A chronic blood disorder in which the bone marrow makes too many red blood cells, white blood cells, and platelets. This leads to a higher concentration of hemoglobin with larger amounts of red blood cells, which is the main feature of this disease. But with time, the high platelet count may become more of a problem and patients can suffer from problems with blood clots because of this and their “thickened” blood. Although it is not a true cancer, it often turns into acute myelogenous leukemia (AML) after many years.
