You cannot tell if you have leukemia by how low your neutrophils are. The main reason you can’t judge leukemia by the neutrophil value is that there are many types of leukemia, and different types of leukemia have different values of neutrophils, which can be increased, normal or decreased. In the case of acute lymphoblastic leukemia, neutrophils are lowered, mainly due to the proliferation of lymphocytes, which inhibits the production of neutrophils. In the case of acute granulocytic leukemia, which is characterized by an abnormal malignant proliferation of granulocytes, a large number of granulocytes are present in the bone marrow, in which case the neutrophils are elevated and also belong to leukemia. In addition, a decrease in neutrophils can be seen in leukemia, but also in aplastic anemia, juvenile idiopathic arthritic diseases. Therefore, it is not possible to determine whether a person has leukemia by the size of the neutrophil count. After the onset of leukemia, there may be a reduction in the three cell lines, granulocytopenia, thrombocytopenia, erythrocytopenia, and patients often have symptoms of anemia, infection and bleeding. If the patient has neutropenia, dizziness, fever, pneumonia or skin bleeding, bleeding gums, skin petechiae, ecchymosis, menorrhagia, nosebleeds and other symptoms should be noted. Prompt medical attention is needed.
