What causes adenopathy?
Adenopathy is usually caused by an accumulation of immune cells and fluid inside a lymph node as part of your body’s response to an infection. Adenopathy can also be caused by an abnormal accumulation of circulating immune cells, due to cancer, an infectious abscess or other inflammatory triggers.
Among the common causes of adenopathy are strep throat, ear infections, and mononucleosis.
Infectious causes of adenopathy
Bacterial and viral infections are among the common causes of adenopathy. Examples include:
- Fungal or parasitic infections
- Infectious mononucleosis
- Other bacterial or viral infections
- Some sexually transmitted diseases
- Staphylococcus bacteria (staph)
- Streptococcus bacteria (strep)
- Tuberculosis (serious infection affecting the lungs and other organs)
- Upper respiratory viral infections
Noninfectious causes of adenopathy
Noninfectious causes of adenopathy include:
- Drug hypersensitivity (antiseizure medications, antibiotics, allopurinol)
- Inflammation in response to a foreign body
- Lymphoma (cancer of the lymph nodes)
- Secondary (metastatic) cancers that spread from other regions of the body
- Systemic autoimmune disorders like sarcoidosis, lupus, rheumatoid arthritis, or amyloidosis
What are the risk factors for adenopathy?
Anyone can get adenopathy, and the risk factors vary widely depending on the cause of the adenopathy. A small number of factors increase the risk of developing adenopathy. Not all people with risk factors will get adenopathy. Risk factors for adenopathy include:
- Current history of cancer
- Family history of cancer
- Frequent infections
What is adenopathy?
Adenopathy, also referred to as lymphadenopathy, is the enlargement of lymph nodes anywhere in your body. Lymph nodes are a part of your immune system and are where immune cells mature to fight infection and unfamiliar antigenic substances. Inflamed lymph nodes often indicate an infection or illness affecting nearby tissues.

How is adenopathy treated?
Treatment of adenopathy depends on the underlying cause. Adenopathy caused by a bacterial infection is treated with antibiotics. Over-the-counter pain relievers can also be helpful for symptomatic treatment associated with adenopathy.
If adenopathy is due to cancer, treatment is directed at the underlying type of cancer and will vary widely.
