What is buttock lymph nodes?

Buttock lymph nodes are part of the lymphatic system, which is responsible for helping the body fight infection and disease. They are located in the gluteal region, which is the upper part of the buttocks.

The function of the buttock lymph nodes is to filter lymph fluid from the lower extremities, pelvis, and lower abdomen. Lymphatic vessels carry lymph fluid which contains white blood cells, proteins, and other substances that help fight off infections. When lymphatic vessels pass through the buttock lymph nodes, the lymph fluid is filtered and any harmful substances or pathogens are removed.

The buttock lymph nodes can become enlarged or swollen due to various reasons, such as infections, cancer, injury, or inflammation in the surrounding area. If the lymph nodes in the buttock area are enlarged, a doctor may perform tests to determine the cause and develop a treatment plan. In some cases, surgery or radiation therapy may be recommended to remove or shrink enlarged lymph nodes.
