When a routine blood test suggests the possibility of leukemia, further diagnostic tests such as bone marrow aspiration, biopsy, and immunophenotyping are required to confirm the diagnosis. Leukemia can be divided into acute leukemia and chronic leukemia. Acute leukemia includes acute myeloid leukemia and acute lymphoblastic leukemia. Acute myeloid leukemia is further categorized into eight types, from M0 to M7. Acute lymphoblastic leukemia is divided into three subtypes: L1 to L3. Chronic leukemia can be divided into chronic myeloid leukemia and chronic lymphocytic leukemia.

Symptoms of Acute Leukemia

The common symptoms of acute leukemia include four main categories: infection, anemia, bleeding, and tumor infiltration. Symptoms of infection manifest as fever, cough, expectoration, chest pain, abdominal pain, diarrhea, frequent urination, urgent urination, painful urination, skin infections, and perianal infections. Anemia is characterized by dizziness, fatigue, poor appetite, and decreased endurance. Symptoms of reduced platelets mainly involve bleeding, which can manifest as bleeding of the skin and mucous membranes, organ bleeding, and even cerebral hemorrhage. Tumor infiltration can manifest as gingival hyperplasia and skin rashes among other swellings.

Is bleeding when brushing teeth leukemia?

Bleeding during brushing is not necessarily leukemia; it could also be due to gingivitis or periodontitis. Bleeding can occur around the teeth where there are irritants like soft plaque or dental plaque. These irritants chronically stimulate the gingival tissues, causing them to be in a congested state. A stimulus, such as brushing, can then lead to bleeding of the gums. This condition is a common early sign of gingivitis or periodontitis. After dental cleaning to remove these irritants, followed by rinsing and medicating the area around the gums, the condition of gingivitis can be improved. Therefore, if bleeding during brushing can be improved through dental cleaning and medication, it indicates that the bleeding is simply caused by gingivitis or periodontitis, and not leukemia.

How is leukemia treated?

Leukemia treatment currently mainly consists of three aspects: supportive care, chemotherapy, and transplantation. Supportive care refers to actively preventing and treating infections, as well as transfusing red blood cells and platelets in leukemia patients, who often suffer from repeated infections, anemia, and bleeding. Chemotherapy can be divided into oral chemotherapy and intravenous chemotherapy, depending on the specific type of leukemia. Transplantation can be divided into autologous hematopoietic stem cell transplantation and allogeneic hematopoietic stem cell transplantation. Autologous transplantation costs less and has fewer side effects but has a higher relapse rate. Allogeneic transplantation is more costly, has more severe side effects, but a lower relapse rate. Whether to undergo autologous or allogeneic hematopoietic stem cell transplantation depends on the specific type of disease and the patient's individual circumstances.

Chronic Granulocytic Leukemia Classification

Chronic granulocytic leukemia is a myeloproliferative tumor originating from pluripotent stem cells, characterized by the presence of the Philadelphia chromosome or changes in the BCR/ABL fusion gene. Chronic granulocytic leukemia progresses through four stages: asymptomatic, chronic, accelerated, and blast crisis phases. Most patients are diagnosed after the onset of symptoms. Only a very few patients are diagnosed through routine physical examinations or other reasons when blood abnormalities are discovered. The earliest symptoms experienced during the chronic phase of the illness typically include fatigue, dizziness, and abdominal discomfort. The accelerated phase is a transitional stage before the blast crisis, marking a turning point where the disease worsens. It is often difficult to distinctly separate the accelerated phase from the blast crisis, and about 20%-25% of patients may enter the blast crisis phase directly without passing through the accelerated phase.
