There are about 1, cases each year. Generally affects older adults. Juvenile myelomonocytic leukemia JMML Is an uncommon blood cancer that have overlapping features of two other types of blood cancers.
Large granular lymphocytic LGL leukemia is a type of chronic leukemia affecting white blood cells called "lymphocytes. LGL leukemia is characterized by enlarged lymphocytes, containing noticeable granules, which can be seen when the blood is examined under the microscope.
B-cell prolymphocytic leukemia B-PLL is a very rare and typically aggressive malignancy cancer characterized by the out of control growth of B-cells B-lymphocytes. B-cells are a type of white blood cell that is part of the immune system. B-PLL usually affects older adults with a median age at diagnosis of 69 years, and it is slightly more common in men than women.
T-cell prolymphocytic leukemia T-PLL is an extremely rare and typically aggressive malignancy cancer that is characterized by the out of control growth of mature T-cells T-lymphocytes. Health Alert:. Learn More. Explore this Section.
What is Leukemia? What Causes Leukemia? Types of Leukemia The four most common types of leukemia are: Acute lymphocytic leukemia Acute myeloid leukemia Chronic lymphocytic leukemia Chronic myeloid leukemia Acute lymphocytic lymphoblastic leukemia ALL ALL is more common in children. ALL can affect the bone marrow all over the body. It can also spread to the: Lymph nodes Liver Spleen Doctors further sub-classify ALL based on the variety and developmental stage of the lymphocyte involved.
Blood stem cells in the bone marrow form into either: Lymphoid cells, which become white blood cells. Myeloid cells, which can become red blood cells, white blood cells, or platelets. More subtypes of CLL exist that affect other types of cells. Chronic myeloid leukemia CML This type of leukemia is rare.
Adults are more likely than children to get CML. A subtype of CML can form very quickly. This type is hard to treat. Hairy cell leukemia A rare type called hairy cell leukemia HCL — because of how it looks under a microscope — affects fewer than 6, people each year. HCL grows slowly.
Some people live with the disease for many years before symptoms appear. Leukemia Prognosis Prognosis — or chance of recovering from leukemia — depends on many factors.
A lower white blood cell count at the time of diagnosis is predictive of a better outcome. Leukemia Risk Factors Common risk factors for leukemia include: Benzene exposure — benzene is a carcinogen that often makes up other chemicals, such as plastics and rubbers. People who work in industries that use benzene may be at increased risk. Radiation exposure — people exposed to high levels of radiation from treatment for other cancers or from nuclear weapons are at increased risk.

Medically reviewed by Shuvani Sanyal, MD. According to data from the National Cancer Institute Surveillance, Epidemiology, and End Results SEER Program , chronic lymphocytic leukemia is the most common type in the United States, followed by acute myeloid leukemia, chronic myeloid leukemia and acute lymphocytic leukemia. Acute lymphocytic leukemia ALL progresses rapidly, replacing healthy cells that produce functional lymphocytes with leukemia cells that can't mature properly. The leukemia cells are carried in the bloodstream to other organs and tissues, including the brain, liver, lymph nodes and testes, where they continue to grow and divide.
The growing, dividing and spreading of these leukemia cells may result in a number of possible symptoms, some of which may resemble the flu. They include fatigue, shortness of breath, fever, and easy bruising or bleeding , among other symptoms. ALL develops when changes in DNA mutations cause the bone marrow to produce too many abnormal lymphocytes a type of white blood cell.
Lymphocytes are supposed to help fight infections, but the ones produced in people with ALL are unable to do so properly. The proliferation of these abnormal cells also crowds out other types of healthy blood cells. Risk factors for ALL include:.
ALL may be diagnosed with blood tests and a bone marrow aspiration and biopsy, which involve extracting a sample of bone marrow and a tiny piece of bone, then studying the cells under a microscope. Acute myeloid leukemia AML , also known as acute myelogenous leukemia, acute myeloblastic leukemia, acute granulocytic leukemia or acute nonlymphocytic leukemia, is a fast-growing form of cancer of the blood and bone marrow. Some symptoms may resemble the flu—such as fever, fatigue and night sweats.
Others include easy bruising or bleeding and weight loss. Blood tests and bone marrow aspiration and biopsy are among the tests that may be done to diagnose this cancer. Chronic lymphocytic leukemia CLL is a typically slow-growing cancer that begins in lymphocytes in the bone marrow and extends into the blood. It may also spread to lymph nodes and organs such as the liver and spleen. CLL develops when too many abnormal lymphocytes grow, crowding out normal blood cells and making it difficult for the body to fight infection.
When it does cause symptoms, these may include swelling in the lymph nodes neck, underarm, stomach or groin , fatigue, fever, infection, weight loss and more.
