Maladies et problèmes de santé
Leukemia is the most common form of cancer diagnosed in children and acute lymphoblastic leukemia, or ALL as it’s commonly called, is the most common type of leukemia. ALL is a cancer of the blood and bone marrow, and it affects the body's white blood cells (WBCs). Normally, these cells help fight infection and protect the body against disease. But in leukemia, these cells turn cancerous and multiply when they shouldn't, resulting in too many abnormal WBCs.
