Secondary polycythemia is the most common cause of polycythemia. It occurs in reaction to chronically low oxygen levels , medications, other genetic mutations that impact the body's ability to transport or detect oxygen, or, rarely because of certain cancers.
In oncology, polycythemia vera (PV) is an uncommon myeloproliferative neoplasm in which the bone marrow makes too many red blood cells. [1] The majority of cases [2] are caused by mutations in the JAK2 gene, most commonly resulting in a single amino acid change in its protein product from valine to phenylalanine at position 617.

Symptomatic features of paraneoplastic syndrome cultivate in four ways: endocrine, neurological, mucocutaneous, and hematological.The most common presentation is a fever (release of endogenous pyrogens often related to lymphokines or tissue pyrogens), but the overall picture will often include several clinical cases observed which may specifically simulate more common benign conditions.
In hematology, essential thrombocythemia (ET) is a rare chronic blood cancer (myeloproliferative neoplasm) characterised by the overproduction of platelets (thrombocytes) by megakaryocytes in the bone marrow. [3] It may, albeit rarely, develop into acute myeloid leukemia or myelofibrosis. [3]
The disorder cannot be associated with eosinophil-based tissue damage or a primary or secondary cause of eosinophilia. That is, it is a diagnosis of exclusion and has no known cause. Over time, this disorder can resolve into a primary hypereosinophilia, typically clonal hypereosinophilia, chronic eosinphilic leukemia, or an eosinophilia ...
Endometrial cancer is the most common form of cancer of the female reproductive organs in the U.S., with 67,880 new cases diagnosed each year.Over the past decades, rates have increased and ...
A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
