Where are the lymph nodes?

The National Cancer Institute (NCI) dictionary says there are hundreds of lymph nodes throughout the body, connected to one another by lymph vessels, and that clusters are found in the neck, axilla (underarm), chest, abdomen, and groin. MedlinePlus lists common areas where lymph nodes can be felt with the fingers: the groin, the armpit, the neck, under the jaw and chin, behind the ears, and on the back of the head.

What do lymph nodes do?

According to the NCI dictionary, lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. MedlinePlus calls them an important part of the immune system and says they help the body recognize and fight germs, infections, and other foreign substances.

MedlinePlus explains that the term "swollen glands" refers to enlargement of one or more lymph nodes and that the medical name is lymphadenopathy. Infections are the most common cause, and painful lymph nodes are generally a sign that the body is fighting an infection. MedlinePlus also notes that a nearby lymph node is often the first place a cancer spreads. A lymph node biopsy is among the tests MedlinePlus says may be done.
