Leukemia and other cancers share biological characteristics, as clonality. In acute myelogenous leukemia (AML), the predominant cells are the youngest recognizable precursors (myeloblasts) of the neutrophils of the blood. The bone marrow produces immature cells that develop into leukemic white blood cells called lymphoblasts. In ALL, the majority of the cases, the transformation affects the B lineage cells. Leukemia starts in the soft, inner part of the bones (bone marrow), but often moves quickly into the blood. In ALL, there’s an increase in a type of white blood cell (WBC) known as a lymphocyte.
