Myelofibrosis

September 20 was Myelofibrosis Awareness Day in the US, see http://bit.ly/SfKg8I You wouldn't expect there to be much awareness of this or other myeloproliferative neoplasms in the UK, but it would be good if there was an information website on all rare blood cancers. What does exist? Either the most elementary descriptions of these diseases, or papers from learned journals that require detailed knowledge of haematology to be understood, with nothing in between.
