@barbarian1 Bone marrow is an easy test these days. IT can be done with conscious sedation if you are concerned about pain etc. Surprisingly for me it was pretty easy and fast. Results clarify status . Sedation took care of worry and pain. Do not avoid test if your hem/onc recommends. IT is crucial to knowing where you are and then they have a good idea if treatment is needed or if you are a watch and wait. The results will not change for the better. They either stay the same or change not for the better. Do not delay. When and if treatment does become necessary an early catch and start are better than catching after progression to a critical stage.
