How can bone marrow test help in the diagnosis of acute myeloid leukemia (AML)?

ANSWER

Acute myeloid leukemia (AML) is a type of cancer that keeps immature stem cells from growing into healthy blood cells. To confirm that you have AML, you'll need a bone marrow test. The doctor will place a needle into a bone -- usually near your hip -- and remove a little bit of fluid or a small piece of bone.

The sample will go to a lab for testing. A doctor called a pathologist will look at your cells under a microscope. If 20% or more of the blood cells in your bone marrow are immature, you may be diagnosed with AML.
