Hi @trarenrut, ultimately your health isn’t in the hands of your hematologist/oncologist. It’s in your hands. You sound concerned about your continually high white blood count and I’m wondering if you have actually been able to talk to your oncologist about your concerns.

WBCs can fluctuate daily as an immune response. Multiple factors can raise WBC for example: Infections, underlying inflammation, stress, smoking, allergies, bacterial or viral infections and certain drugs, etc..
Treatment for high white blood cell counts usually involves addressing the underlying cause rather than phlebotomy. That’s generally used to reduce excess iron or lower blood volume.
What is your actual diagnosis that has you on Jakafi the past few years?
