My husband is 53 years old and in excellent health -- doesn't drink, exercises regularly. He has a bicuspid aortic valve that is being managed with Lisinopril, and he had a prostate biopsy last year that came back negative, and since then, his PSA is within normal range. Last month he had a routine physical and his wbc came back at 1.9 with neutrophil ABS at 0.4. He has received no treatment thus far, the doctor has adopted a "wait and see" attitude and ordered weekly cbc's. This last week's was: wbc at 2.8 and neutrophile ABS at 0.7 (down from 0.8 the week before). All other counts are normal, it's just the neutrophils that are way off. He has been tested for vitamine b-12 and folate deficiencies, HIV, ANA are negative, and we do not remember him having ANY type of viral infection except a slight cold maybe in early June. Sed rate is 4. He has no symptoms of illness whatsoever and feels "perfect".
Of course I'm worried about leukemia or MDS. We see the hematologist next week, but she doesn't seem overly concerned like we are. I would expect the next course to be a bone marrow biopsy, but how worried should I be about this neutropenia?
