How is Lymphoma Diagnosed?
Lymphoma is diagnosed through a series of tests that may include blood tests, bone marrow tests, and imaging tests. Each of these tests provides different information that helps in the diagnosis and staging of the disease.
Blood Tests:
- Complete Blood Count (CBC): This test measures the amount of different types of blood cells in a sample of your blood. Abnormal levels of white blood cells, red blood cells, or platelets may suggest lymphoma.
- Blood Chemistry Tests: These tests measure the levels of various substances in the blood that can indicate how well your organs are functioning and if lymphoma has affected them.
- Lactate Dehydrogenase (LDH) Levels: High levels of this enzyme in the blood can be a sign of cell damage and rapid cell turnover, which can indicate lymphoma.
- Immunophenotyping: This test identifies cells based on the types of proteins or markers present on the surface of the cells. It can help determine the type of lymphoma.
Bone Marrow Tests:
- Bone Marrow Aspiration and Biopsy: These tests involve taking a small amount of bone marrow, blood, and a small piece of bone from your hipbone or breastbone to look for lymphoma cells. The samples are examined under a microscope to determine if lymphoma cells are present.
- Cytogenetic Analysis: This test looks at the chromosomes of cells from samples of blood, bone marrow, or lymph nodes to see if there are any changes that might indicate lymphoma.
Imaging Tests:
- Computed Tomography (CT) Scan: This test uses x-rays to make detailed pictures of sections of the body where lymphoma might be present, such as the neck, chest, abdomen, and pelvis.
- Magnetic Resonance Imaging (MRI): This test uses magnetic fields, not x-rays, to produce detailed images of the body. It can help determine the extent of the disease.
- Positron Emission Tomography (PET) Scan: This test uses a small amount of radioactive glucose (sugar) to find cancer cells in the body. It is often used in conjunction with a CT scan (known as a PET/CT scan).
A Summary of Diagnosing Lymphoma
Diagnosing lymphoma involves a comprehensive evaluation that includes a physical examination, medical history, and a variety of tests. These tests may include blood tests, bone marrow tests, and imaging tests. The results of these tests help doctors determine the type and stage of lymphoma, which are crucial factors in deciding the best treatment approach.
