When they do the bone marrow (BM) procedure they should do a molecular panel which looks at 400 genes commonly associated with blood cancers. The JAK2 mutation is common among many different blood cancers. The BM and molecular panel should identify what type of blood cancer your husband has. When you get the results you should have a long talk with your Hematologist/Oncologist. We're here for further information but first, get the appropriate tests done.

Good luck.

Thanks for the question. I was diagnosed with Thrombocytosis, Essential Thrombocythemia and JAK2 gene mutation over 3 years ago. It is a form of blood cancer that is not very life threatening. The MPN Foundation has been most helpful to my understanding. I chose to avoid chemotherapy drugs prescribed by my oncologist. I take 325 mg ASA daily and have a platelet count every three months. The MDs try to frighten me into drugs or stroke, but I believe the cure may be worse than the disease. If you have a medical background, you may take a very different view. I hope this helps with your anxiety. I live with the disease daily and travel, work and play a full life at 73.
