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.
The end result is usually a lack of red blood cells â which causes the anemia characteristic of myelofibrosis â and an overabundance of white blood cells with varying levels of platelets. In people with myelofibrosis, the normally spongy bone marrow becomes scarred.
