Dr. Anand Patel of the University of Chicago explains that
myelofibrosis (
MF) is a subtype in the family of chronic blood cancers called
myeloproliferative neoplasms (
MPNs)
—caused by abnormal signaling in the bone marrow that disrupts normal blood cell production. He describes how MF differs from related conditions such as polycythemia vera and essential thrombocythemia due to
increased bone marrow scarring. Dr. Patel discusses how this scarring can lead to low blood counts, spleen enlargement, and other complications, and explains that MF can range from a slow-moving disease to more aggressive forms. He also outlines the differences between
primary myelofibrosis and
secondary myelofibrosis, which can develop from polycythemia vera or essential thrombocythemia.
