Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with normal blood cell production. [1] Symptoms may include feeling tired, shortness of breath, easy bruising and bleeding, and increased risk of infection. [1]
These blood cells are not fully developed and are called blasts or leukemia cells. [2] Symptoms may include bleeding and bruising, bone pain, fatigue, fever, and an increased risk of infections. [2] These symptoms occur due to a lack of normal blood cells. [2] Diagnosis is typically made by blood tests or bone marrow biopsy. [2]
Acute lymphoblastic leukemia (ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. [1] Symptoms may include feeling tired, pale skin color, fever, easy bleeding or bruising, enlarged lymph nodes, or bone pain. [1]
Leukocytes. Symptomatic Hyperleukocytosis (Leukostasis) is defined by a tremendously high blast cell count along with symptoms of decreased tissue perfusion.Leukostasis is associated with people who have bone and blood disorders and is very common among people with acute myeloid leukemia or chronic myeloid leukemia.
When a child has leukemia, the cells do not respond to the signals telling them when to stop and when to produce cells. The bone marrow becomes crowded, resulting in problems producing other blood cells. [4] [5] Common childhood leukemia signs and symptoms include excessive tiredness, easy bruising or bleeding, bone pain and paleness. [6]
Chronic lymphocytic leukemia; Other names: B-cell chronic lymphocytic leukemia (B-CLL) [1] Peripheral blood smear showing CLL cells: Specialty: Hematology and oncology: Symptoms: Early: None [2] Later: Non-painful lymph nodes swelling, feeling tired, fever, weight loss, night sweats [2] Usual onset: Older than 50 [3] Risk factors
T-lymphoblastic cells of acute leukemia in the bone marrow. In some cases, the cytoplasm is concentrated at one pole of the cell, forming "hand mirror cells". Specialty: Haematology, oncology: Symptoms: Recurrent infections, unusual or common bleeding and bruising, extreme tiredness, unexplained fever, unexplained weight gain, swollen lymph nodes
Chronic myelomonocytic leukemia (CMML), not to be confused with chronic myelogenous leukemia or CML characterized by less than 20% myeloblasts in the bone marrow and greater than 1*10 9 /L monocytes (a type of white blood cell) circulating in the peripheral blood.
