Summary Summary. Listen. 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.
Fibrosis is the formation of excessive fibrous connective tissue in place of healthy tissue. The disease myelofibrosis - or MF - (one of the myeloproliferative neoplasms) is characterized by fibrosis in the bone marrow. This reduces the bone marrow's ability to produce blood cells. Prognosis for sufferers of myelofibrosis varies. The prognosis of myelofibrosis is different for every patient.
