Acute myeloid leukemia (AML) starts in the bone marrow -- the spongy tissue inside your bones where blood cells are made. The disease prevents immature blood cells from growing into healthy blood cells. You have three main types of blood cells:

__White blood cells fight infections.
__Red blood cells carry oxygen around your body.
__Platelets clot your blood when you're injured.

In the early stages of AML, as your body makes fewer healthy blood cells, you might feel like you've come down with the flu or another illness. Symptoms can include:
__Tiredness
__Fever
__Loss of appetite
__Weight loss
__Night sweats

A lot of other things can cause those symptoms, too. So you and your doctor would work together to find the cause.
