ON THIS PAGE: You will learn about how doctors describe ALL. This is called subtype and classification. Use the menu to see other pages.

For example, flow cytometry (see Diagnosis) distinguishes between ALL involving T cells or B cells. Specific chromosomal or genetic changes in the cancer cells are used to help plan treatment and predict prognosis.
