Myelofibrosis is a rare and chronic bone marrow disorder characterized by the abnormal production and accumulation of fibrous tissue in the bone marrow. This condition disrupts the normal production of blood cells, leading to anemia, thrombocytopenia, and enlargement of the spleen. Myelofibrosis can be primary (idiopathic) or secondary to other bone marrow disorders such as polycythemia vera or essential thrombocythemia. Understanding the causes, symptoms, diagnosis, treatment, and management of myelofibrosis is essential for providing comprehensive care to affected individuals.
