Nyirokcsomómegnagyobbodás

Nyirokcsomómegnagyobbodás, often referred to as lymphadenopathy in medical literature, is a condition characterized by the swelling of one or more lymph nodes. Lymph nodes are small, bean-shaped glands that are part of the lymphatic system, a network of vessels and organs that help the body fight infection and disease. They are located throughout the body, including the neck, armpits, and groin.

When the body encounters an infection, such as a common cold or the flu, lymph nodes can swell as they work to filter out the pathogens. This is a normal immune response, and the swelling typically subsides once the infection clears. However, persistent or significant swelling of lymph nodes can indicate a more serious underlying condition.

Causes of nyirokcsomómegnagyobbodás are diverse and can range from common viral or bacterial infections to autoimmune diseases like lupus or rheumatoid arthritis. In some cases, lymphadenopathy can be a symptom of cancer, particularly lymphoma or leukemia, or a sign that cancer has spread from another part of the body to the lymph nodes. Certain medications can also cause lymph node swelling as a side effect.

Diagnosis usually involves a physical examination to assess the size, tenderness, and mobility of the swollen nodes. Further investigations may include blood tests, imaging scans like ultrasound or CT scans, and in some instances, a lymph node biopsy to examine the tissue for abnormal cells. Treatment depends entirely on the underlying cause. If it's an infection, antibiotics or antiviral medications may be prescribed. For more serious conditions, specific treatments for the underlying disease will be necessary.
