To diagnose what might be causing your swollen lymph nodes, your doctor may check your medical history. A physical exam near the surface of your skin is also suggested. Size, tenderness, warmth, texture and the site of your swollen lymph nodes will offer clues to the underlying cause.
A Blood tests can be conducted depending on what your doctor suspects is causing your swollen lymph nodes. The tests will include a complete blood count (CBC). This helps evaluate your overall health and detect a range of disorders, including infections and leukemia.
A chest X-ray or computerized tomography (CT) scan of the affected area may help determine potential sources of infection or find tumors.
In Lymph node biopsy, a sample from a lymph node or even an entire lymph node will be remove for microscopic examination.
Some swollen lymph nodes return to normal when the underlying condition, such as a minor infection, gets better. Treatment for swollen lymph nodes from other causes depends on the cause:
- Bacterial infection can be cure by antibiotics. If your swollen lymph nodes are cause by virus or an HIV infection you need to have specific treatment for that condition.
- Immune disorder. If your swollen lymph nodes are a result of certain conditions, such as lupus or rheumatoid arthritis, treatment is directed at the underlying condition.
- Cancer. Swollen nodes caused by cancer require treatment for the cancer. Treatment may involve surgery, radiation or chemotherapy depending on the type of cancer.
