When this happens, blood cell production becomes abnormal. Exposure to high levels of radiation is a known risk factor for ALL as well as acute myeloid leukemia (AML). This type of cancer usually gets worse quickly if it is not treated. To confirm the diagnosis and identify the specific type of leukemia, a needle biopsy and aspiration of bone marrow from a pelvic bone will need to be done to test for leukemic cells, DNA markers, and chromosome changes in the bone marrow. The bone is made up of compact bone, spongy bone, and bone marrow. Leukemia is an umbrella term that includes many different types of blood cancer, each one of them depending on what cell line is affected.Leukemia is a complex ailment that may include several alterations and severe symptoms that usually require hospitalization until the patient is stable. x�mZɎeG�?��?зs�4� ^ �Qɦ$W!٬�{Ή)_U!K]y^N�1G\��?�������~���q=~{��Ի�v�u�V�o����ߘ������/O׿��Hw�����wZ�{Nف�?�t�2��G�w^��[�z�ր�Kj��L��]�3o��vۂ���Go�˃�~{�i�Ev�J��������~�Z�˽����.
