What distinguishes polycythemia from polycythemia vera?
Polycythemia is a general term that means having too many red blood cells in your blood. It can happen for various reasons, including as a response to low oxygen levels or other conditions.
Polycythemia vera (PV), on the other hand, is a specific type of blood cancer classified as a myeloproliferative neoplasm. In PV, your bone marrow produces too many red blood cells due to genetic mutations, most commonly the JAK2V617F mutation.
The key differences are:
* Polycythemia is a symptom or finding that can have multiple causes
* Polycythemia vera is a specific cancer diagnosis where abnormal cells in your bone marrow continuously overproduce red blood cells
With PV, the excess red blood cells thicken your blood, increasing the risk of dangerous blood clots, stroke, or heart attack. PV can also cause elevated white blood cells and platelets, along with symptoms like itching, enlarged spleen, headaches, and blurry vision.
PV is a chronic, progressive condition that requires ongoing monitoring and treatment to manage blood cell counts and reduce complications.
