Myelofibrosis is a serious bone marrow disorder that disrupts your body's normal production of blood cells. The result is extensive scarring in your bone marrow, leading to severe anemia, weakness, fatigue, and often, an enlarged spleen and liver.

Myelofibrosis — also called agnogenic myeloid metaplasia or idiopathic myelofibrosis — can occur at any age, although it mainly develops after age 50.

Many people with myelofibrosis get progressively worse, and some eventually develop a serious form of leukemia. Yet it's also possible to have myelofibrosis and live symptom-free for years. Treatment for myelofibrosis, which focuses on relieving symptoms, can involve a variety of options.
