This is a conversation between two students at Pasadena City College.
            
            
Duke's friends who with a sign and symptoms like leukemia have just .
            
sends .
            
to hospital. Duke is a little worried and uncomfortable about Adult .
            
Acute .
            
Leukemia. At the same time, Jeff presents many valid arguments in favor .
            
of .
            
it. Duke presents many medical questions that Jeff answers.
            
Duke: Hey, Jeff. One of my good friends has just sent to hospital with .
            
a .
            
suspect of leukemia, which made me worried and uncomfortable. And there .
            
are .
            
many medical questions, such as: what is leukemia, what are the key .
            
statistics for adult acute leukemia, risk factor, classified, symptoms, .
            
diagnosed and treated, should be answered.
            
Jeff: I am so sorry to hear that. And I was just doing a project with .
            
generally leukemia. Leukemia is cancer of the white blood cells. This .
            
cancer .
            
starts in the bone marrow but can then spread to blood, lymph nodes, .
            
the .
            
spleen, liver, central nervous system and other organs. In contrast, .
            
other .
            
types of cancer can start in these organs and then spread to the bone .
            
marrow .
            
or elsewhere. Those cancers are not leukemia. Both children and adults .
            
can .
            
develop leukemia.
            
Duke: what is the difference between normal blood cells and leukemia .
            
cells?.
            
Jeff: blood cells form in the bone marrow, which is the soft material .
            
in the .
            
center of most bones. Most blood cells mature in the bone marrow and .
            
then .
            
move into the blood vessels. In people with leukemia, the bone marrow .
            
produces abnormal white blood cells. The abnormal cells are leukemia .
            
cells. .
            
When they crowd out normal white blood cells, red blood cells, and .
            
platelets, which makes it hard for blood to do its work.
            
Duke: Is it only one disease? What are the key statistics for adult .
            
leukemia?.
            
Jeff: No, it is a complex disease with many different types and .
            
sub-types. .
            
The leukemia that adult developed is called Adult Acute Leukemia. About .
            
30,600 new cases of leukemia will be diagnosed in the United States .
