In the United States, about 53,000 adults are diagnosed with leukemia each year. The most common type of leukemia in adults is acute myeloid leukemia (AML), which accounts for about 30% of all cases. Other types of leukemia include acute lymphoblastic leukemia (ALL), chronic myeloid leukemia (CML), and chronic lymphocytic leukemia (CLL).

Leukemia is diagnosed through a blood test. The blood test will look for abnormal cells in the blood. If abnormal cells are found, a bone marrow biopsy may be necessary to confirm the diagnosis.
What Are the Treatment Options for Leukemia?
The treatment options for leukemia depend on the type of leukemia, the stage of the leukemia, and the patient’s overall health. Treatment options may include:
- Chemotherapy
- Radiation therapy
- Targeted therapy
- Immunotherapy
- Stem cell transplant
Can Leukemia Be Cured in Adults?
The cure rate for leukemia varies depending on the type of leukemia and the stage of the leukemia. However, the overall cure rate for leukemia in adults is about 60%.
What Are the Risk Factors for Leukemia?

- Gender: Men are more likely to develop leukemia than women.
- Race: White people are more likely to develop leukemia than black people or Asian people.
- Family history: People who have a family history of leukemia are more likely to develop leukemia.
- Exposure to radiation: People who have been exposed to high levels of radiation are more likely to develop leukemia.
- Certain chemicals: Exposure to certain chemicals, such as benzene, can increase the risk of leukemia.
How Can I Reduce My Risk of Leukemia?
There is no sure way to prevent leukemia, but there are a number of things you can do to reduce your risk, including:
- Avoid exposure to radiation.
- Avoid exposure to certain chemicals, such as benzene.
