Red Blood Cells: Polycythemia Vera

Polycythemia vera, though the causes are unknown, happens when the body makes too many red blood cells. Typically, excess red blood cells do not create problems in the body, however, in some individuals it may result in blood clots forming in the body, stopping the flow of blood to vital areas, and other patients may experience other symptoms such as thickening of the blood that results in bleeding. If left untreated, polycythemia vera can process into more serious forms of cancer such as myelofibrosis.
