Childhood Leukemia Severity and Treatment

Michale Jonas

Blood has three types of cells: white blood cells that fight infection, red blood cells that carry oxygen, and platelets that help blood clot. Every day, your bone marrow makes billions of new blood cells, and most of them are red cells. When you have leukemia, your body makes more white cells than it needs. These leukemia cells can’t fight infection the way normal white blood cells do. And because there are so many of them, they start to affect the way your organs work. Over time, you may not have enough red blood cells to supply oxygen, enough platelets to clot your blood, or enough normal white blood cells to fight infection.
