Diagnosis of Leukemia
by Michael Jubinville, MPH
Blood tests may be the first sign of a problem. They may be done as part of a routine exam. Tests may also be done if there are unexplained symptoms. Swollen lymph nodes, unusual bruising, a lot of infections, or anemia may be caused a blood disorder. They can also be caused by other issues. Tests will help to find the cause.
Diagnosis of Leukemia
Blood tests will show changes in blood cells. Tests include:
Bone Marrow Aspiration and Biopsy
Bone marrow test is the only way to confirm leukemia.
A bone marrow aspiration takes a sample of bone marrow through a needle. It is often taken from the hipbone. A piece of bone may also be removed for biopsy.
Both marrow and bone sample are looked at in a lab.
Results from those tests and new tests will show details about the leukemia. It will help to make a treatment plan.
Other tests may include:
Acute leukemias are aggressive from the start. They are in bone marrow sites all over the body. Cancer often spreads to other organs. Doctors group these by type so they can find the best way to treat them.
Chronic leukemias are not as aggressive. This can change over time. Chronic leukemias are grouped by the type and phase when it is found. In the US, a Rai classification is used for chronic lymphocytic leukemia:
Treatment and outcomes depend on many factors such as the grouping, overall health, and age
