Acute lymphocytic leukemia (ALL) progresses rapidly, replacing
healthy cells that produce functional lymphocytes with leukemia
cells that can't mature properly. The leukemia cells are carried in
the bloodstream to other organs and tissues, including the brain,
liver, lymph nodes and testes, where they continue to grow and
divide. The growing, dividing and spreading of these leukemia cells
may result in a number of possible symptoms. |
Chronic lymphocytic leukemia (CLL) is a typically slow-growing
cancer that begins in lymphocytes in the bone marrow and extends
into the blood. It may also spread to lymph nodes and organs such
as the liver and spleen. CLL develops when too many abnormal
lymphocytes grow, crowding out normal blood cells and making it
difficult for the body to fight infection. |
Acute myeloid leukemia (AML), also known as acute myelogenous
leukemia, acute myeloblastic leukemia, acute granulocytic leukemia
or acute nonlymphocytic leukemia, is a fast-growing form of cancer
of the blood and bone marrow. |
Chronic myeloid leukemia (CML), also known as chronic
myelogenous leukemia, begins in the blood-forming cells of the bone
marrow and then, over time, spreads to the blood. Eventually, the
disease spreads to other areas of the body. |
