I have a question to the public or any doctor out there that would dignify an answer. My brother-in-law is experiencing a drop in platelets, about 30,000 and the white blood count is 2.5, and the bone marrow biopsies have come back negative for any cancer. Ct scan of the spleen is normal and they cannot figure out what is wrong, so therefore have offered no treatment. What should we do and can you offer what should be the next course of action besides a third bone marrow biopsy? Should we seek a second opinion from another Hematologist oncologist or is it really a waiting game till some other symptom appears. So far he is a-symptomatic except for tiredness, but nothing unusual. he never gets sick and says he feels fine! Help!
