LYMPHADENOPATHY

What are lymph nodes?

Lymph nodes are located throughout the body and are part of the lymphatic system. The basic function of the lymphatic system of the body is immunity. Lymph nodes usually occur in groups. They act as "filters" for parts of the body. Some lymph nodes are close to the skin surface making them easy to notice. These lymph nodes may give early clues to infection and malignancy.

How are large lymph nodes treated?

We usually observe swollen lymph nodes for a period of time before removing them. Most lymph node swelling is a reaction to ongoing infection. Many times a virus can cause the lymph nodes to swell. This requires no treatment. For some infected lymph nodes, antibiotics may be given. Sometimes, they develop into an abscess (acute localized infection caused by tissue destruction with swelling and inflammation) that may need to be drained. Lymph nodes are removed only if they remain large and don't shrink. If you have any further questions, feel free to ask your doctor.
