Leukemia

Leukemia is a cancer that starts in blood stem cells (immature blood cells) in the bone marrow. Bone marrow is the soft, spongy material that fills the centre of most bones.

There are several different types of leukemia. The 4 main types of leukemia are: Acute Lymphoblastic Leukemia (ALL),  Acute Myelogenous Leukemia (AML), Chronic Lymphocytic Leukemia (CLL) and Chronic Myelogenous Leukemia (CML)
