Polycythemia vera (PV) is currently classified among the bcr/abl-negative, "classic" myeloproliferative disorders (MPDs), which also include essential thrombocythemia (ET) and primary myelofibrosis (PMF). Precautionary measures, such as blood tests, may be required before oral healthcare is undertaken and a close communication and cooperation is required between the treating hematologist and the oral healthcare provider.

Blood Cancer Journal. Concepts of genetics and immunology help define the origin and behaviour of the disease: the tracking of allele burdens of mutations (genetic dosage), the timing or order of acquired mutations, the import of bystander mutations and the onco-inflammatory response; all theories are invoked to explain the progression of disease severity and potential transformational leukaemia. Polycythemia vera is a rare, chronic disorder involving the overproduction of blood cells in the bone marrow (myeloproliferation). Rare disease umbrella organizations focus on improving the lives of all those impacted by rare diseases through education and advocacy efforts.
