question: Hi This is Rashmi from Delaware just want to ask a question regarding my mother . My mother has been diagnosed with Poem syndrome where found some myeloma in bone marrow , she is in India . She is seeing one Oncologist , he is giving her chemotherapy medicine by mouth . Oncologist said that after medicine they need to check again weather the level of Myeloma went down or not .Question is does she really need to go for bone marrow test again to check the level or the whole body test or blood test (ESR in blood )can also tell how much improvement is there?
