Myelofibrosis is rare, affecting fewer than 2 of 100,000 people in the United States. http://msd-bahamas.com/mmhe/sec14/ch178/ch178c.html
Myelofibrosis can progress to acute lymphocytic leukemia or lymphoma
Myelofibrosis goes by many names including idiopathic myelofibrosis, agnogenic myeloid metaplasia, chronic myelosclerosis, aleukemic megakaryocytic myelosis, and leukoerythroblastosis
Myelofibrosis is caused by an abnormality in a single stem cell, which causes it to grow out of control
Idiopathic myelofibrosis typically becomes progressively worse and can cause death
About one quarter of all patients with myelofibrosis have no symptoms (asymptomatic)
Because symptoms are similar to other diseases (mostly leukemias), myelofibrosis is not easy to diagnose
