General information about MPN

There are three main types of MPN:

  • Polycythaemia vera (PV)
  • Essential thrombocythaemia (ET)
  • Myelofibrosis (MF)

The type of MPN you have depends on the type of blood cell your body is making too many of. To find out more about a specific type of MPN, choose a type from the menu above.

There are around 520 cases of MPN in the UK each year.

MPN is classed by the World Health Organisation (WHO) as types of blood cancer. This means your care and treatment follows national cancer guidelines and you should have access to cancer support services.

Although MPN is classed as a cancer, many people with MPN feel quite well and the condition doesn’t interfere too much with everyday life.

Often, MPN can remain stable or progress quite slowly.
