Leukemia Symptoms & Signs, Causes and Screening | AMO

Commonly known as “blood cancer”, it usually originates in the bone marrow, causing massive proliferation of abnormal white blood cells. Under normal circumstances, hematopoietic stem cells in the bone marrow gradually divide into different cells such as red blood cells and white blood cells. Any abnormality in the process, however, would produce abnormal blood cells that circulate in the blood. There are four types of leukemia: chronic lymphocytic leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, and acute myeloid leukemia.
