Leukaemia is the most common cancer seen in children. Leukaemia is a type of blood cancer that occurs in early blood-forming cells, usually in the white blood cells, and is found in the blood or bone marrow. Acute lymphoid leukaemia (ALL) and Acute myeloid leukaemia (AML) are the two types of leukemia. Acute lymphoid leukaemia (ALL) involves abnormal growth of a type of immature white blood cell called lymphoblasts. Acute myeloid leukaemia (AML) involves abnormal growth of another type of white blood cell called myeoblasts and monoblasts. #WorldBloodCancerDay
