Chronic myeloid leukemia, scientifically known as chronic granulocytic leukemia, is mainly characterized by myeloid hyperplasia, leukocytosis of peripheral blood, splenomegaly, and other clinical manifestations, which can be specified through various stages, such as the chronic stage, accelerated stage, and acute stage. 1. Chronic phase: patients will have anemia, spleen discomfort, bleeding, fatigue, low fever, weight loss, etc., which is mainly related to hypersplenism caused by leukocytosis. 2. Accelerated stage: patients may have symptoms such as low fever, splenomegaly, worsening anemia, bleeding, bone pain, and weight loss. 3. Acute stage: progressing to acute leukemia, patients may have symptoms such as unexplained fever, enlarged spleen, bone pain, bleeding, enlarged lymph nodes, and soft tissue lumps on the skin. Chronic granulocytic leukemia has different stages and clinical symptoms, and needs to receive standardized treatment under the guidance of physicians.
