Myelofibrosis (MF) is a rare bone marrow disease that disrupts how the body produces blood cells. Because the disease develops slowly and doesn’t always present noticeable symptoms, it can be hard and difficult to diagnose. If your primary care doctor suspects MF, they will likely conduct a series of tests including a physical exam, blood test, and imaging test. Polycythemia vera (PV) is another serious bone marrow condition, and more than 15 percent of people with PV will develop MF. Take a look at these articles to learn more about MF including treatment options and what to expect after receiving a diagnosis.
