ON THIS PAGE: You will learn about how doctors describe ALL. This is called subtype and classification. To see other pages, use the menu.
To help plan treatment and predict prognosis, doctors divide ALL into subtypes and classify the disease based on the type of lymphocytes that are affected. 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 predict how well treatment is likely to work and may guide the treatment choices.
