Myeloproliferative neoplasm
Myeloproliferative neoplasm (mye-lo-pro-lif-er-a-tive ne-o-plasm) is a type of disease that occurs when the body makes too many white or red blood cells, or platelets. This condition is considered a type of blood cancer.
Etymology
The term "myeloproliferative" comes from the Greek words "myelos" meaning marrow, and "proliferate" meaning to reproduce or multiply. "Neoplasm" is derived from the Greek "neo" meaning new, and "plasma" meaning formation. Thus, the term refers to the excessive formation of new cells in the marrow.
Types of Myeloproliferative Neoplasms
There are several types of myeloproliferative neoplasms, including:
- Polycythemia vera (pol-i-cy-the-mia ve-ra): A slow-growing blood cancer where your bone marrow makes too many red blood cells.
- Essential thrombocythemia (es-sen-tial throm-bo-cy-the-mia): A rare disorder where the body produces too many blood platelets.
- Primary myelofibrosis (pri-mary mye-lo-fi-brosis): A disorder where your bone marrow is replaced with fibrous scar tissue.
- Chronic myelogenous leukemia (chronic mye-lo-genous leu-ke-mia): A type of cancer that causes bone marrow to produce too many white blood cells.
Symptoms
Symptoms of myeloproliferative neoplasms can vary greatly, but may include fatigue, weakness, increased susceptibility to infections, and easy bruising or bleeding.
Treatment
Treatment for myeloproliferative neoplasms often involves managing symptoms and complications. Treatments may include medication, blood transfusions, or in some cases, a bone marrow transplant.
