Acute Lymphoblastic Leukaemia (ALL)

Acute Lymphoblastic Leukaemia (ALL), also known as Acute Lymphocytic Leukaemia or Acute Lymphoid Leukaemia, is a type of Leukaemia that starts from the white blood cells in the bone marrow. It develops from a type of white blood cells that are central to the immune system called lymphocytes, or from lymphoblasts, an immature form of lymphocytes. ALL causes the body to make too many lymphocytes, that aren’t able to fight infection very well. This buildup of lymphocytes in the blood crowds out the healthy blood cells causing infections, anaemia and easy bleeding. ALL is the most common type of childhood leukaemia usually occurring in children (2 to 5 years) and also the most successfully treated. It may also occur in adults.
