###Human: How to proceed with the blood cancer treatment for my 8-year-old son? ###Assistant: Dear, Your son may have leukemia and there are so many types of lukemia. Just with CBC leukemia cannot be confirmed. And there are multiple tests that has to be done. Fluid tests may not show positive results in a single test. It may be repeated. They must have done flow cytometry and thta will give you better idea regarding the condition. Is he having fever or any other complaints? sore those? Bone marrow transplantation will be done only after subtyping leukemia. Chemotherapy will be usually started after knowing diagnosis but if child is sick enough or if it is not going to affect the test result, they may start chemo early and wait for the test results. Hope it's useful. let me know with some more details. I would like to give my opinion.
