The most common types are: - [Acute Myeloid Leukemia (AML)](): A rapid-growing cancer characterized by the accumulation of immature myeloid cells, known as myeloblasts, in the bone marrow and blood. - [Chronic Myeloid Leukemia (CML)](): A slower-growing cancer that typically affects older adults, characterized by the presence of an abnormal chromosome called the Philadelphia chromosome.
