Leukemia

Patent Granted Leukemia /luːkiːmiːɑː/ (American English) or leukaemia (British English) is a group of cancers that usually begin in the bone marrow and result in high numbers of abnormal white blood cells.[1] These white blood cells are not fully developed and are called blasts or leukemia cells. Symptoms may include bleeding and bruising problems, feeling very tired, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically by blood tests or bone marrow biopsy.
