Acute myelogenous leukemia is caused by damage to the DNA of developing cells in your bone marrow. When this happens, blood cell production goes awry. The bone marrow produces immature cells that develop into leukemic white blood cells called myeloblasts. These abnormal cells are unable to function properly, and they can build up and crowd out healthy cells.

It's not clear what causes the DNA mutations that lead to leukemia. Radiation, exposure to certain chemicals and some chemotherapy drugs may play a role. It's believed that most cases of acute myelogenous leukemia aren't inherited.
