How is B-cell lymphoma diagnosed?

Healthcare providers use a range of tests to diagnose B-cell lymphoma:

• Complete blood count (CBC). A CBC measures and counts your blood cells. Providers use CBC to detect a variety of illnesses.
• Blood chemistry test. This test measures the number of certain substances in your blood.
• Computed tomography (CT) scan. CT scans use a series of X-rays and a computer to create three-dimensional images of your soft tissues and bones.
• Positron emissions tomography (PET) scan. Providers inject a radioactive tracer into your body to detect early signs of cancer.
• Magnetic resonance imaging (MRI). This is a painless test that uses a large magnet, radio waves and a computer to produce very clear images of organs and structures within your body.
• Lumbar puncture (spinal tap). To do this test, your healthcare provider inserts a needle into your lower back to get a sample of cerebrospinal fluid, the clear liquid that surrounds your spine and brain.
• Bone marrow biopsy. To do this test, providers insert a special needle through your skin and into your pelvic bone or breastbone so they can remove a small sample of bone marrow from inside it.
