Many people think of leukemia as a blood cancer predominantly of children, but it can occur at any age, says James McCloskey, M.D., a leukemia specialist at John Theurer Cancer Center at Hackensack University Medical Center. “Certain kinds of leukemia are very common in children,” he says. “Other types of leukemia are more common in adults.”

Leukemia is one of the most common blood cancers diagnosed in adults and in children in the U.S., according to the National Institute of Health’s National Cancer Institute. In adults, it is most often diagnosed in people aged 65 to 74.

There are two main types of leukemia:

  • Acute leukemias including lymphoblastic (also called lymphocytic) leukemia (ALL), Acute myelogenous leukemia (AML)
  • Chronic leukemias including Chronic lymphocytic leukemia (CLL) and Chronic myelogenous leukemia (CML)

Early Symptoms of Acute Leukemia

Early symptoms may be fairly subtle but usually develop quickly, Dr. McCloskey says.

Common symptoms include:

  • Shortness of breath
  • Fatigue
  • Unexplained fever
  • Night sweats
  • Unexplained weight loss
  • Loss of appetite
  • Bone pain
  • Bruising
  • Bleeding

Frequently, people learn there’s something wrong as a result of having blood work done for something else, says Jamie Koprivnikar, M.D., another leukemia expert at John Theurer Cancer Center.

Dr. McCloskey cautions. “Any time a person is experiencing a symptom that seems out of the ordinary to them, they should listen to their instincts and see their primary care physician,” Dr. McCloskey says.

Adds Dr. Koprivnikar, “The best place to start is always with your primary care doctor. They know you, and they have some prior labs that provide a baseline sense of what’s normal for you.”

Who Is at Risk of Leukemia?

In general, there aren’t any risk factors making it more likely you’ll get leukemia, says Dr. Koprivnikar.

“For most patients, we really don’t understand why they develop the disease,” she says. “Most patients don’t have any risk factors. They’re often left wondering why this happened to them.”

That said, there is a higher incidence of the disease among those of Hispanic ethnicity and those who had certain types of chemotherapy or radiation to treat an earlier malignancy, Dr. Koprivnikar says.
