How does your doctor figure out which stage (phase) of chronic myelogenous leukemia you are in?

ANSWER

To figure out the phase of your chronic myelogenous leukemia, your doctor takes a blood and bone marrow sample and counts the number of "blast" cells -- immature cells that grow into white blood cells. The more blast cells you have, the later the phase.
