Acute lymphoblastic leukaemia, illustration - Illustrazioni stock

Computer illustration of a cross-section of blood vessel from a patient with acute lymphoblastic leukaemia (ALL) showing abundant lymphoblasts (purple). Leukaemia is a malignant disease in which the bone marrow and other blood-forming tissues overproduce certain types of white blood cells. These immature and abnormal cells suppress the normal production of white and red cells, thereby increasing the susceptibility to other diseases such as anaemia.
