Myeloproliferative neoplasms (MPN)

Myeloproliferative neoplasms (MPNs) are slow-growing blood cancers that develop when cells in your bone marrow grow out of control and make too many blood cells. There are different types of MPN depending on which type of blood cell is being over-produced.

Myelofibrosis (MF)

In myelofibrosis (MF), your bone marrow makes too many immature blood cells that cause your bone marrow to become inflamed and scarred. Your bone marrow becomes filled with scar tissue. This stops it making enough healthy blood cells.
