I was annoyed that such an important Cancer Charity in the UK still referred to MPN as a disease and put it under headings of Pre-cancerous conditions.
An Internet search for ET led me to the Macmillan website where I was given this out of date information.
The proper classification of MPN's is significant when people need to make claims for medical insurance and for prescriptions for chemotherapy.
Macmillan do a lot of good for Cancer patients and their families, and usually provide very good information. Perhaps some e-mails would help to get this site up to date?
