Most of us are struggling with low hemoglobin. This is the delivery of oxogen to the cells. Here is the problem. having low hemoglobin drives tumor angiogenesis and tumor growth. If you have low hemoglobin you must urgently deal with this. I forced my oncologist to run feritin and iron blood work. My feritin came back high iron low. They are now doing an iron infusion to fix my low iron. This will lead to less overall cancer growth. A very simple thing that no one is doing that may have a large impact. If your hemoglobin is low simply ask them to check iron level on your next blood work and get this dealt with right away!
