What is MF?
Myelofibrosis (MF) is one of the myeloproliferative disorders (MPDs). It is also known as agnogenic myeloid metaplasia or meylofibrosis with myeloid metaplasia. In this condition the bone marrow (the place in the body that produces blood cells) becomes scarred or fibrosed. This scarring occurs because there are too many cells (fibroblasts) in the marrow. Having too many fibroblasts in the marrow can in turn stop the bone marrow from making blood cells.
