The lymph system is made up of lymph nodes and vessels (tiny tubes that carry blood throughout your body). These lymph nodes and vessels run throughout your body to drain extra fluid and return it to the blood near your heart. Lymph nodes filter (clear out) viruses, dying cells, foreign matter, and bacteria to fight infection and keep us safe. The lymph system also recycles proteins throughout your body.
Lymphedema is swelling that is caused by a buildup of fluid that happens over a long period of time (chronic swelling). When lymph fluid is not moving well through the lymph system, it builds up in the tissues and causes swelling.
If you have head and neck cancer, lymphedema can happen in any part of the head, neck, or face. There are many lymph nodes in these areas. Lymphedema can happen after cancer treatment because parts of the lymph system have been removed or harmed by surgery or radiation. Scar tissue from these treatments can also change how the lymph system works.
Lymphedema happens 2 to 6 months after treatment. Lymphedema can happen internally (inside the body) or externally (closer to the outer parts of the body):
You can have internal lymphedema, external lymphedema, or both.
The more lymph nodes removed or harmed during treatment, the higher the chance of having lymphedema. It is normal to have swelling during and shortly after treatment that gets better on its own, but this is not lymphedema. Your provider will know the difference between normal swelling and lymphedema. The normal swelling from surgery often goes away, but if it lasts more than 6 weeks, you may need treatment for it.
The most common first symptoms of lymphedema are swelling, skin tightness, and achiness. A provider will check for these symptoms and look for any signs of lymphedema. If swelling is found, the provider may measure the swelling or rate it using a special scale for lymphedema.
Symptoms of head and neck lymphedema vary, depending on where and how bad the edema is. Symptoms can be:
The earlier lymphedema is treated, the better the outcome. You may be referred to a therapist who specializes in lymphedema to learn how to lower your risk of getting lymphedema, like:
If you have been diagnosed with lymphedema, your treatment will most likely use complete decongestive therapy (CDT). CDT uses:
It is important to find a therapist who has specialized training in lymphedema. Therapy is often done in two phases.
In serious cases, you may need to be followed closely as the swelling could block your airway, making it hard to breathe. Lymphedema in patients with head and neck cancer is manageable when diagnosed and treated early. Report any symptoms to your provider. If you feel like the swelling is making it hard to breathe, call 911 right away. Learn more about lymphedema on OncoLink.
