There are clusters of lymph nodes near the elbow, behind the knee, along the large airways tracheobronchial , along the aorta paraaortic , and many other regions of the body.
There are many conditions in which lymph nodes become involved. Doctors use the term lymphadenopathy to describe inflammation or swelling in these glands. When doctors evaluate lymph nodes there are a number of terms they may use:. Since lymph nodes store the white blood cells that are our first line of defense against infection, they are often enlarged due to infections.
It is good in the sense that they are the powerhouses storing immune cells. This concept was not always well understood, however, and for a long time it was thought that removing the tonsils would help prevent infections. When tonsils are severely damaged, removing them can be a good idea.
But if they are healthy and only doing their job, removing them gets rid of the functional "first place" where bacteria traveling in the lymphatic vessels could be "arrested. Lymph nodes can catch viruses and bacteria but are also susceptible to infections themselves. For those who have been told to watch for a "red streak" after an injury have learned that infections usually staph or strep may begin in an infected wound and spread rapidly along lymph channels.
Infections involving the lymph nodes often cause a significant fever and chills. Cat scratch fever is an infection caused by the bacterium Bartonella henselae and is transmitted by exposure usually via a break in the skin from an infected cat. Lymph nodes are commonly involved with cancer, but their role often differs between solid tumors and lymphomas. With solid tumors such as breast cancer , the cancer cells usually travel to lymph nodes before traveling metastasizing to other regions of the body.
Cancers that have spread to lymph nodes are usually a higher stage than those that have not, meaning they have a greater risk of recurring or spreading. In a sense, the spread of cancer cells to lymph nodes has declared its intent to travel elsewhere. With lymphomas , in contrast, the cancer begins in the lymph nodes.
When lymphomas spread to regions other than lymph nodes, it is not referred to as metastasis as with solid tumors, but rather as "extranodal involvement. There are many other conditions that can cause enlarged lymph nodes, ranging from autoimmune diseases such as rheumatoid arthritis to genetic syndromes, sarcoidosis, and more. Since the lymph nodes are the rest stops for the "workers" or the white blood cells which clean up a site of trauma, they are often enlarged with any injury.
You can think of the lymph nodes as being a truck stop near a natural disaster where the firemen and paramedics are hanging out ready to do their job.
We often think of lymph nodes as heralding disease, but most of the time they are performing their job in fighting off foreign invaders. Even with solid tumors, the lymph nodes are catching the first cancer cells to travel before they can move farther in the body.
