Hi @Littleone, welcome to the Forum.
The confusion youāre feeling makes sense as pre-fibrotic myelofibrosis (which is what I think youāre referring to) sits in its own category, and because it can look very similar to Essential thrombocythemia ('ET'), the two can be tricky to tell apart. Itās part of the same family of blood cancers (myeloproliferative neoplasms, or MPNs), and the JAK2 mutation is very common across all of them. Our myelofibrosis information page also covers pre-fibrotic MF and might help.
If youād like to talk it through with some actual experts (which Iām definitely not!), you can call our support line and speak to one of our nurses on 0808 2080 888, or email support@bloodcancer.org.uk.
Keep posting whenever you need to, weāre here.
Take care,

Hi @Littleone and welcome to the forum.
It can be so confusing canāt it. I like to know exactly what I have and where it sits so I understand your frustration.
I think it would be useful to give the helpline a call as they may be able to help.
How are you doing at the moment? Diagnosis can be a difficult time as itās a lot to process.

Hello there @Littleone, welcome to the forum. Iām glad you found us!
All this really is confusing, I feel for you. In 2023 I was also diagnosed with the JAK2 gene mutation, which people with Myeloproliferative neoplasms ('MPN') often have, like dear @Ceri_BloodCancerUK says. I went onto being diagnosed with Polycythaemia vera ('PV').
To be honest, I hadnāt heard of Prefibrotic Myelofibrosis before you joined the forum, it sounds like itās similar to Essential thrombocythemia ('ET'). Hereās some information about it researched by Blood Cancer UK: What is myelofibrosis? | Blood Cancer UK
Hereās information about testing for Myelofibrosis (āMFā) which gives an idea of the kinds of testing you might expect: Tests for myelofibrosis (MF) | Blood Cancer UK
Hereās the Blood Cancer UK information about Myeloproliferative neoplasms ('MPN') for when you fancy reading more about our family of blood disorders: What are myeloproliferative neoplasms (MPN)? | Blood Cancer UK
I wonder if you have the contact details for the doctor who diagnosed you? You could contact them directly to ask for more details when ready. I always keep a notepad nearby these days as thereās bound to be lots of medical language used by our specialists. Iād also suggest having a loved one with you during appointments to help take notes and offer support.
Once youāre sure what youāve been diagnosed with I bet itāll feel a bit less confusing. It helped me get some ideas of ways to deal with my diagnoses once I could read about what to expect.
Do please let us know how you get on @Littleone.

I spoke to the doctor and she said I have pre myloid frombosis and I asked ( as I have read) if she could tell me life expectancy and she said No 2 medium if that means anything to anybody x

Hello @Littleone and thank you for sharing. I think it is myelofibrosis that your doctor is talking about. Hopefully it will encourage you to know that I have lived with myelofibrosis for over thirty years. I was diagnosed at the age of thirty five. Much more is known and understood about this blood cancer these days and there are many more new treatments for it. I have learnt over the years that it seems to be a variable condition and no two patients are going to be exactly the same. You refer to it as āpre myloid frombosisā but, as I say, I guess it is actually myelofibrosis. Anyway, I am happy to share my experiences if it would help you, but obviously I am not a doctor and can only speak from the perspective of a fellow patient. Thinking of you and wishing you well.

Hi @Littleone, glad you got some extra clarity. And what a lovely thing to have Willow share her experience, thank you @Willow 
Regarding the āNo 2 mediumā comment, thatās the kind of thing our blood cancer nurses could help explain in plain English if it would be useful. You can give them a ring for free on 0808 2080 888 (option 1) or drop them an email at support@bloodcancer.org.uk.
Take care,

@littleone I was diagnosed with post Polycythaemia vera ('PV') myelofibrosis in 2023 after 24 of Polycthemia Vera.
I donāt know what no 2 medium means. I was classified as intermediate risk group one and given a prognosis based on this although it was only a median survivable rate based on the risk group.
I did go on a clinical trial and the treatment has helped me greatly.
The two bits of advice I would give is get a Myeloproliferative neoplasms ('MPN') specialist involved in your care as MF is very rare. And consider any clinical trials that are available.
