My mom has ILC & is having a lumpectomy. Her CBC was norm except low RBC (4.05) & high immature granulocytes (.04 k/mcL). Is this concerning?

Hemoglobin. The graulocyte count is not of concern. What is her hemoglobin. RBC count suggests that it is low and you should discuss with her doctor about giving her iron and vitamin supplements to correct anemia.
