Detailed explanation-1: -As the stem cells of the blood develop, they become blast cells (blasts), which are immature blood cells. In leukemia, there is an overproduction of blast cells. These blast cells develop abnormally and don’t develop into mature blood cells.
Detailed explanation-2: -Acute leukemia is rapidly progressing and results in the accumulation of immature, functionless blood cells in the bone marrow. With this type of leukemia, cells reproduce and build up in the marrow, decreasing the marrow’s ability to produce enough healthy blood cells.
Detailed explanation-3: -Acute myeloid leukemia (AML) starts in the bone marrow (the soft inner part of certain bones, where new blood cells are made), but most often it quickly moves into the blood, as well.
Detailed explanation-4: -The Leukemia & Lymphoma Society notes that the increase in the number of immature WBCs prevents the bone marrow from making healthy red blood cells (RBCs) and platelets. Therefore, in addition to increasing the WBC count, CML may cause a decrease in the RBC count.
