Detailed explanation-1: -Polycythemia vera (pol-e-sy-THEE-me-uh VEER-uh) is a type of blood cancer. It causes your bone marrow to make too many red blood cells. These excess cells thicken your blood, slowing its flow, which may cause serious problems, such as blood clots. Polycythemia vera is rare.

Detailed explanation-2: -If you have polycythemia vera, blood tests might reveal: More red blood cells than normal and, sometimes, an increase in platelets or white blood cells. A greater percentage of red blood cells that make up total blood volume (hematocrit measurement)

Detailed explanation-3: -Polycythaemia vera (PV) is pronounced pol-ee-sigh-thee-me-a vee-rah. Poly means many and cythaemia relates to blood cells. It is also sometimes called erythrocytosis, which means too many red blood cells.
