Summary Summary. Myelofibrosis is a disorder of the bone marrow, in which the marrow is replaced by fibrous (scar) tissue. When the bone marrow is scarred, it cannot make enough blood cells. This leads to anemia, weakness, fatigue, and often, swelling of the liver and spleen.
1 There is no known way to prevent myelofibrosis, except in cases caused by exposure to radiation or industrial chemicals. 2  Patient history and physical examination are necessary. 3  Blood tests show abnormal numbers and appearance of blood cells.  A bone marrow biopsy is necessary for a definite diagnosis.
