Hi all, Diane Hertzog asked me to post this for her: She was called by an oncologist who has a mom breastfeeding an adopted baby. (Diane doesn't know how much milk mom is producing). Mom is 44; at sometime in the past had a bone marrow malignancy. She now has an elevated alkaphosphatase level, which is indicative of either an infection, malignancy, or loss of bone density through loss of calcium. The physician's question is, is the elevated level due to a reoccurance of the malignancy or is it due to decreased bone density from breastfeeding? Any takers on this one? It isn't in any of the books. Has anyone ever measured alkaphosphatase levels in breastfeeding women to see what the normals are??? TIA Jan B -- wondering here in Wheaton.
