Cancers that have moved into the lymph nodes tend to be more advanced. Often, the risk of recurrence is higher in these patients than those without lymph node involvement. Removing cancerous lymph nodes can help keep a cancer from spreading further or coming back.
But it can sometimes result in lymphedema , a condition where lymph fluid backs up in the part of the body where a node used to be. Lymphedema can cause swelling and nerve discomfort or dysfunction, but the good news is that lymphedema can often be managed or even cured.
Your doctor can help you weigh the benefits and risks of having cancerous nodes removed. Share This. View all posts. What role do lymph nodes play in the body? Why do lymph nodes sometimes swell? Therefore, imaging technologies such as X-rays, MRIs, ultrasound, or CAT scans are also used to spot any enlargements or irregularities. A lymph node biopsy is also typically part of the diagnosis process.
Your cancer surgeon will usually remove one or two of the nearby lymph nodes to see if they show any evidence of cancer. When any of the following symptoms accompany swollen lymph nodes, seek medical attention. These symptoms include:. If your doctor has indicated that you should have a lymph node screening and are located in Colorado, please find the RMCC location that is most convenient for you and call to request an appointment.
Your primary care physician or oncologist should be able to recommend a screening provider near you if you are not located close to one of our cancer treatment centers. Request an Appointment.

How Lymph Nodes and Cancer are Related Cancer can appear in lymph nodes either from spreading from the original location, or it can begin in the lymph nodes It is crucial to keep in mind that cancer in the lymph nodes does not necessarily mean you have lymph node cancer.
Lymph Node Screening If you have a cancer diagnosis, it is likely tests will be run to see if the lymph fluid shows evidence of cancer cells. That is the focus of this section. When cancer cells break away from a tumor, they can travel to other areas through either the bloodstream or the lymph system.
If they travel through the lymph system, the cancer cells may end up in lymph nodes. Most of the escaped cancer cells die or are killed before they can start growing somewhere else. But one or two might settle in a new area, begin to grow, and form new tumors. This spread of cancer to a new part of the body is called metastasis. In order for cancer cells to spread to new parts of the body, they have to go through several changes. They must become able to break away from the original tumor and attach to the outside wall of a lymph or blood vessel.
Then they must move through the vessel wall to flow with the blood or lymph to a new organ or lymph node. When cancer does spread to lymph nodes, it usually spreads to nodes near the tumor itself. These are the nodes that have been doing most of the work to filter out or kill the cancer cells.
But if there are only a few cancer cells in a lymph node, it may look and feel normal. Lymph nodes deep in the body cannot be felt or seen. So doctors may use scans or other imaging tests to look for enlarged nodes that are deep in the body.
Often, enlarged lymph nodes near a cancer are assumed to contain cancer. The only way to know whether there is cancer in a lymph node is to do a biopsy. Doctors may remove lymph nodes or take samples of one or more nodes using needles.
