SWOLLEN LYMPH NODES

Lymph nodes also called lymph glands, play a vital role in your body’s ability to fight off infections. They function as filters, trapping viruses, bacteria and other causes of illnesses before they can infect other parts of your body. Swollen of these nodes may occur when you are exposed to bacteria or viruses. When swollen lymph nodes are caused by an infection, this is known as lymphadenitis. Other swollen lymph nodes are caused by cancer although this a rarely case.

In some cases, the passage of time and warm compresses may be all you need to treat swollen lymph nodes. Treatment of lymphadenitis depends on the cause.

Your lymphatic system is a network of organs, vessels and lymph nodes situated throughout your body. Common areas where you might notice swollen lymph nodes include your neck, under your chin, in your armpits and in your groin.

  • Runny nose, sore throat, fever and other indications of an upper respiratory infection

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.

  • 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.
