Acute Lymphocytic Leukemia (ALL)

Acute lymphocytic leukemia (ALL) is a cancer of the blood and bone marrow—the soft, spongy tissue inside bones where blood cells are produced. The term “acute” indicates that the disease progresses rapidly and involves the overproduction of immature blood cells rather than fully developed ones. “Lymphocytic” refers to lymphocytes, a type of white blood cell affected by the disease. ALL is also known as acute lymphoblastic leukemia. ALL is the most common type of cancer in children, and with modern treatments, the chances of cure are high. Although it can also occur in adults, treatment outcomes are generally less favorable compared to those in children.
