Can kidney cancer cause weight gain?

Yes, leukemia can be missed in a CBC (Complete Blood Count) as it is not a definitive diagnostic test for leukemia. CBC is a blood test that measures the levels of various types of blood cells in the body, such as white blood cells, red blood cells, and platelets. In leukemia, the white blood cell count may be abnormally high or low, but it is not always the case. In some cases, the CBC may show no abnormalities at all. To diagnose leukemia, additional tests such as bone marrow biopsy or flow cytometry are needed to detect abnormal cells and determine the type and subtype of leukemia. In summary, CBC can provide some indications that may suggest the presence of leukemia, but it is not enough to diagnose the disease definitively. Therefore, if there is a suspicion of leukemia, further testing must be done to confirm the diagnosis.
