my 81 yo mother's primary care physician is sending her to a hematologist oncologist next month because she has enlarged red blood cells, macrocytosis, liver is slightly elevated, but the B12 and folate levels are normal (she does take supplements). Other words have been thrown out there like MDS, Bone Marrow Dsplasia, leukopenia is down and polycythemia is up, DNA synthesis deficiency...I'm thinking Leukemia. So at 81 and other illnesses to boot, what happens if she decides not to treat it. Is it a painful aweful death or is it treatable...she pretty worn out...just had two angioplasties in legs and had stent put in after heart attach about 3 years ago.
