Polycythemia Vera, or "PCV" for short, is a disorder of the bone marrow in which too many Red Blood Cells (RBC's) are produced. There are other types of Polycythemia will be discussed. PCV is not actually "cancer", since the Red Blood Cells that are overproduced to not go on to divide themselves. Rather, it is a "myeloproliferative disorder", which simply means that too many NORMAL Red Blood Cells are being made. A problem with any myeloproliferative disorder is that the bone marrow loses "equilibrium" and does not make necessary cells in the proper ratios. This impacts all the cells normally produced by the bone marrow. 1) Lymphocytes 60% in children, 30% in adults-- especially increase with viruses. 2) Neutrophils 30% in children, 60% in adults-- especially increase with bacteria. 3) Monocytes-- about 5-10% in children or adults, increase with viral infections. 4) Eosinophils -- 2-5% in children & adults, increased by allergies or parasites. 5) Basophils-- 1% in children & adults, do not commonly increase with infection.
