• Acute Lymphoblastic Leukemia (ALL) is the most common childhood cancer, but also occurs in adults. 

• ALL develops from the overproduction of immature lymphocytes, leading to too many immature leukemic lymphoblasts in the blood and an imbalance in the normal percentages of cells.

• FISH testing identifies the genetic changes underlying this disease.
