Leukemia
Exams and Tests
If your doctor suspects leukemia, he or she will ask about your medical history. Your doctor also will check for enlarged lymph nodes
in your neck, underarm, or groin. He or she will also examine you to see if your liver or spleen is enlarged.
Your doctor will order blood tests, such as a complete blood count (CBC) and a blood profile. These provide important information about the cells in your blood. They are used to look into symptoms such as fatigue, weakness, fever, bruising, or weight loss.
If your blood work points to possible leukemia, your doctor will want to find out what kind you might have. Different kinds of leukemia need different kinds of treatment.
- A blood test is usually enough to find signs of chronic lymphocytic leukemia (CLL).
- A bone marrow aspiration and biopsy is the key to diagnosing most leukemias.
Unusual cells, chromosomes, or proteins on cells can tell what type of leukemia you have, such as acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), or chronic myelogenous leukemia (CML), or even a subtype. It is important to know if you have a subtype of a leukemia. Different subtypes get better with different kinds of treatment.
Your doctor may also order other tests, including:
- Chest X-rays, to find out if leukemia or an infection is the cause of lung problems such as persistent coughing, coughing up blood, chest pain, or difficulty breathing.
- CT scan of the head, chest, and belly, to find out whether leukemia has spread there.
- Lumbar puncture, to find out whether leukemia cells are in your cerebrospinal fluid (CSF).
- MRI of the brain, to look into symptoms such as confusion, paralysis, numbness, vision problems, vertigo, or headaches. Those symptoms could mean the leukemia has spread to the brain.
Also, a biopsy of a lymph node or other tissues may be done to look for cancer cells.
