This condition can be caused by certain medications and by infections. In some cases, it is caused by a cancer or precancerous condition. Myelofibrosis, bone marrow scarring that can result from various hematologic cancers, typically leads to low blood counts. Pancytopenia can also be caused by aplastic anemia, a bone marrow failure disorder that affects blood cell production.
Myelofibrosis (MF). 1  Is a rare bone marrow cancer. 2  Is a type of chronic leukemia and can occur on its own (primary myelofibrosis) or as a result of another bone marrow disorder. It is one of a related group of blood cancers known as âmyeloproliferative neoplasms (MPNs)â in which bone marrow cells that produce the blood cells develop and function abnormally. 2  The resulting fibrous scar tissue formation leads to severe anemia, weakness, fatigue and an enlarged spleen and liver.
