@topsz, it's not uncommon to pause treatment if blood counts are too low, in your case red blood cells (hemoglobin). Has the blood cell count improved so that you can resume treatment again? What treatment are you getting?

Slightly improved. Was on a radiation clinical trial. Took pluvicto, lupron, zytiga.
