Acute lymphoblastic leukemia, illustration 插畫檔

Illustration of cancerous white blood cell precursors (pink with white spots) resulting from acute lymphoblastic leukaemia (ALL). Healthy red blood cells (red discs) and white blood cells (purple) are seen in the surrounding blood. ALL is a rare cancer in which excess white blood cell progenitor cells called lymphoblasts are produced in the bone marrow. It is the most common form of leukaemia in children, but affects adults as well. Treatment typically involves chemotherapy, immunotherapy or radiotherapy
