Leukemia is a malignant type cancer of the bone marrow and blood. It is defined by the uncontrolled accumulation of blood cells. They are not able to carry out the normal functions of blood cells.
Depending on the type of leukemia, its symptoms is vary. So doctor will always looks for the symptoms first before decided its type. Here are 4 main types of leukemia:
1. Acute lymphocytic leukemia (ALL)
Acute lymphocytic leukemia (ALL) is a fast-growing cancer in which the body produces a large number of immature white blood cells (lymphocytes). These cells are found in the blood bone marrow, lymph nodes, spleen, and other other organs. It affects both children and adults but is more common in children. It accounts for 65% of the acute leukemias in children.
2. Acute myelogenous leukemia (AML)
Acute myelocytic leukemia (AML) is the most common acute leukemia in adults. It is cancer that starts inside bone marrow, the soft tissue inside bones that helps from blood cells. The cancer grows from cells that would normally turn into white blood cells.
3. Chronic lymphocytic leukemia (CLL)
Chronic lymphocytic leukemia (CLL) is cancer of a type of white blood cells called lymphocytes. It is essentially an adult disorder and is almost twice as common as chronic myelocytic leukemia.
4. Chronic myelogenous leukemia (CML)
Chronic myelocytic leukemia (CML) is cancer that starts inside bone marrow, the soft tissue inside bones that helps form blood cells. The cancer grows from cells that produce white blood cells. It is far more common in adults than in children.
