Leukemia is the 10th-most common cancer diagnosed in the United States. But leukemia isn’t just one disease—many types of leukemia originate in different parts of the blood stream and affect different types of blood cells. Also, some leukemias are regarded as acute, meaning they may require aggressive treatments. Others are considered chronic, which means they are slow to develop and may require a less aggressive treatment plan.

What causes leukemia?

Who gets leukemia?

In the United States, an estimated 62,770 Americans will be diagnosed with leukemia in 2024, according to the American Cancer Society. Leukemia is diagnosed more often in men than in women. Although people of any age can develop the disease, it is common in adults over 65 years old.

"There is so much more to the experience of City of Hope than just the treatment. Some people have asked me why I travel for treatment, why I don’t just go somewhere local. Doesn’t it make life complicated? No, it doesn’t. City of Hope takes the worry away. Scheduling, appointments, all of these details are taken care of. My response when people ask me about the inconvenience of traveling for treatment is that all I need to do is get there and get myself home. City of Hope takes care of everything else."

Types of leukemia

Leukemia is categorized by the type of white blood cells affected and by how quickly the disease grows.

Types of leukemia include:

  • Acute lymphocytic leukemia (ALL), also known as acute lymphoblastic leukemia, affects the blood and bone marrow, and progresses rapidly.
  • Acute myeloid leukemia (AML), also known as acute myelogenous leukemia, acute myeloblastic leukemia, acute granulocytic leukemia or acute nonlymphocytic leukemia, affects the blood and bone marrow, and progresses rapidly.
  • Chronic lymphocytic leukemia (CLL) typically grows slowly, beginning in the lymphocytes of the bone marrow and then spreading to the blood.
  • Chronic myeloid leukemia (CML), also known as chronic myelogenous leukemia, begins in the blood-forming cells of the bone marrow and then spreads to the blood.
  • Hairy cell leukemia (HCL) is rare and progresses slowly, developing when bone marrow makes too many B cells.
  • Myelodysplastic syndromes (MDS) are related diseases that develop when the bone marrow produces too few functioning red blood cells, white blood cells or platelets, or any combination of the three.
