    Leukemia is cancer of the body’s blood-forming tissues, including the bone marrow and the lymphatic system.

    Many types of leukemia exist. Some forms of leukemia are more common in children. Other forms of leukemia occur mostly in adults.

    Leukemia usually involves the white blood cells. Your white blood cells are potent infection fighters — they normally grow and divide in an orderly way, as your body needs them. But in people with leukemia, the bone marrow produces abnormal white blood cells, which don’t function properly.

    Treatment for leukemia can be complex — depending on the type of leukemia and other factors. But there are strategies and resources that can help to make your treatment successful.

    Symptoms
    Leukemia symptoms vary, depending on the type of leukemia. Common leukemia signs and symptoms include:

    Fever or chills
    Persistent fatigue, weakness
    Frequent or severe infections
    Losing weight without trying
    Swollen lymph nodes, enlarged liver or spleen
    Easy bleeding or bruising
    Recurrent nosebleeds
    Tiny red spots in your skin (petechiae)
    Excessive sweating, especially at night
    Bone pain or tenderness
    When to see a doctor

    Make an appointment with your doctor if you have any persistent signs or symptoms that worry you.

    Leukemia symptoms are often vague and not specific. You may overlook early leukemia symptoms because they may resemble symptoms of the flu and other common illnesses.

    Rarely, leukemia may be discovered during blood tests for some other condition.

    Causes

    Scientists don’t understand the exact causes of leukemia. It seems to develop from a combination of genetic and environmental factors.

    How leukemia forms

    In general, leukemia is thought to occur when some blood cells acquire mutations in their DNA — the instructions inside each cell that guide its action. There may be other changes in the cells that have yet to be fully understood that could contribute to leukemia.

    Certain abnormalities cause the cell to grow and divide more rapidly and to continue living when normal cells would die. Over time, these abnormal cells can crowd out healthy blood cells in the bone marrow, leading to fewer healthy white blood cells, red blood cells and platelets, causing the signs and symptoms of leukemia.

    How leukemia is classified

    Doctors classify leukemia based on its speed of progression and the type of cells involved.

    The first type of classification is by how fast the leukemia progresses:

    Acute leukemia. In acute leukemia, the abnormal blood cells are immature blood cells (blasts). They can’t carry out their normal functions, and they multiply rapidly, so the disease worsens quickly. Acute leukemia requires aggressive, timely treatment.
    Chronic leukemia. There are many types of chronic leukemias. Some produce too many cells and some cause too few cells to be produced. Chronic leukemia involves more mature blood cells. These blood cells replicate or accumulate more slowly and can function normally for a period of time. Some forms of chronic leukemia initially produce no early symptoms and can go unnoticed or undiagnosed for years.
    The second type of classification is by type of white blood cell affected:

    Lymphocytic leukemia. This type of leukemia affects the lymphoid cells (lymphocytes), which form lymphoid or lymphatic tissue. Lymphatic tissue makes up your immune system.
    Myelogenous (my-uh-LOHJ-uh-nus) leukemia. This type of leukemia affects the myeloid cells. Myeloid cells give rise to red blood cells, white blood cells and platelet-producing cells.
    Types of leukemia

    The major types of leukemia are:

    Acute lymphocytic leukemia (ALL). This is the most common type of leukemia in young children. ALL can also occur in adults.
