Acute myelogenous leukemia (AML) is the most common form of leukemia. About 15% of childhood leukemia cases are AML. This disease is more likely to affect the older individuals.
The average age of diagnosis is 67. Of the patients with AML, less than 6 % are younger than 20 years of age when diagnosed; more than 55 % are diagnosed at 65 years or older.
There will be about 44,240 new cases of leukemia in the United States in 2007. Nearly half of these will be acute leukemias. There will be about 13,410 new cases of AML. Of these, 12,700 will be adults. The incidence of AML is slightly more among men than among women.
