My mother is 76-yrs-old with severe osteoporosis (having had 5 kyphoplasties). Routine bloodwork has show anemia with a dropping hgb of now 8.5 over the last two months. Multiple labs have been drawn and now she has been sent to a hematologist who wants to perform a bone marrow biopsy. My concern is the complications of the bone marrow biopsy at this point. And if the treatment will be the same (i.e.: blood products and Epogen) regardless of the actual diagnosis, should we go ahead with the bone marrow biopsy.
