Lymphatic leukemia includes acute lymphoblastic leukemia and chronic lymphoblastic leukemia. Clinical manifestations include dizziness, fatigue, chest tightness, dyspnea, ecchymosis and petechiae of skin and mucous membranes, hemorrhage of mucous membranes of the oral cavity and the nasal cavity, splenomegaly and lymph node enlargement, and headache, nausea and vomiting when the central nervous system is involved. 1. The normal hematopoiesis of bone marrow in patients with acute and chronic lymphoblastic leukemia will be severely inhibited, resulting in a significant decrease in red blood cell, hemoglobin and platelet counts. Reduced red blood cells and hemoglobin means anemia, which may cause dizziness, fatigue, panic and other symptoms of anemia. 2. Acute and chronic lymphoblastic leukemia patients with abnormal lymphocyte counts in the peripheral blood is significantly higher, so that the blood viscosity increases, hyperviscosity may occur, and the patient may have chest tightness, dyspnea and other manifestations. When the platelet count is significantly lowered, skin and mucous membrane bleeding may occur, which may be manifested as petechiae, ecchymosis, hematoma and so on. 3. Acute and chronic lymphocytic leukemia patients may also have enlarged spleen and enlarged lymph nodes all over the body. Acute lymphoblastic leukemia is more likely to invade the central nervous system, which can lead to a significant increase of leukemia cells in brain tissue and cerebrospinal fluid, which can increase intracranial pressure and lead to headache, nausea and vomiting, and elevated blood pressure, etc. Patients should consult a hematologist promptly. Patients should consult the hematology department in time, complete the relevant examinations such as bone marrow aspiration and biopsy to evaluate the condition, and have the physician formulate an appropriate chemotherapy plan for treatment or undergo bone marrow transplantation.
