Abbreviated AML. Also known as intense myeloid leukemia or intense nonlymphocytic leukemia (ANLL). A quickly progressive cancerous illness in which you will find too many immature blood-forming cells within the bloodstream and bone marrow, the cells being specifically those destined to provide rise to your granulocytes or monocytes, both types of white-blood cells that fight attacks. In AML, these blasts cannot mature and thus become too many. AML can occur in grownups or kids.
