This is one of the most frustrating realities of living with an MPN — and scientists are still working to fully understand it. Even with good disease control, transformation can still happen, and there are a few leading theories as to why. Here are the main theories being explored:

- Selective pressure — Things like chemotherapy, radiation, or exposure to certain chemicals can push the body toward transformation, even when the MPN itself seems controlled.
- Genetic predisposition — Some people may have gene changes in their stem cells from the start that make multiple blood cancers more likely to develop over time, regardless of treatment.
- Accumulated mutations — Over time, additional gene mutations (such as in IDH2 or SRSF2) can build up and increase the risk of transformation. The key takeaway is that current MPN treatments can manage the disease but cannot fully prevent transformation. That's why staying closely connected with a hematologist is so important — regular monitoring can catch any changes early, which makes a real difference in treatment options and outcomes.
