Lymphedema is swelling caused by a build-up of fluid, usually in the arms or legs in patients who have been treated for cancer. Lymphedema is one of the most troubling complications that can develop after cancer surgery. Many patients find that lymphedema worsens the physical and emotional strain of living with (or following treatment for) cancer.
The risk of developing lymphedema depends upon the type of surgery received, the time since surgery, and if radiation therapy was used. Generally, patients who undergo more extensive surgery, have many lymph nodes removed, or have radiation therapy to the axilla (arm pit) or groin after surgery are more likely to develop lymphedema, though even the removal of a single lymph node bears a small risk. Most patients who develop lymphedema do so within two years after their surgery, but it is important to note that it is a lifetime risk, especially in association with new trauma to a limb.
More detailed information about lymphedema, written for healthcare providers, is available by subscription. (See 'Professional level information' below.)
WHAT IS LYMPHEDEMA?
Lymph is a clear fluid that contains mostly protein and white blood cells (the blood cells that fight infection). Lymph vessels drain lymph fluid from the body's tissues and organs. The fluid is filtered through lymph nodes (also called glands) and eventually drains into the bloodstream (figure 1).
Lymphedema can develop if surgery or radiation treatment affects the lymph nodes and vessels. Patients who have multiple lymph nodes removed (eg, a full axillary or inguinal node dissection) are more likely to develop lymphedema than those who have only one or a few nodes removed (eg, sentinel lymph node biopsy). Patients who have both surgery and radiation treatment are at even higher risk.
Lymph node biopsy and dissection are discussed in detail in a separate topic review. (See "Patient education: Surgical procedures for breast cancer — Mastectomy and breast conserving therapy (Beyond the Basics)".)
The initial symptoms of lymphedema may include any or all of the following symptoms in the limb involved in cancer treatment:
●A heavy sensation or an aching discomfort
●Fatigue with use
●Numbness or tingling
In some cases, these symptoms develop before swelling is noticeable. Let your doctor or nurse know as soon as possible if you develop any of these symptoms; recognizing and treating lymphedema in the early stages may reduce its severity or slow its worsening over time.
As mentioned above, the risk of lymphedema is higher in people who have multiple lymph nodes removed (for example, in an axillary lymph node dissection, a procedure in which most or all of the nodes in the underarm area are removed). In some cases, doctors can instead remove only one or a few lymph nodes (called a sentinel lymph node biopsy); this reduces the risk of lymphedema. This may not be an option in some cases, such as if the nodes have already been found to contain cancer cells.
If you have not yet developed lymphedema, monitor your limb by taking arm or leg measurements as instructed by your doctor. Although there are no measures that will prevent lymphedema with certainty, there are some things you can do to that can help reduce severity if it develops.
To avoid trauma and/or injury to the affected limb:
●Keep your skin clean. Wash with a mild soap every day.
●Be careful with your nails. Don't pick at the skin around your nails or cut your cuticles.
●Use lotion to keep your skin from getting dry and cracked.
●Use an electric razor instead of a razor blade to shave.
●Always use sunscreen when you go outside.
●If an arm is affected, wear gloves when gardening, cooking, or doing other things that could hurt your skin.
●If a leg is affected, wear hard-soled shoes when outside.
●If you do get a small cut, scrape, or bite on your arm, hand, leg, or foot, clean it well with soap and water. Then use an antibiotic cream. Call your doctor or nurse if it does not heal quickly or if you have signs of an infection.
●Avoid extreme temperature changes – This includes staying away from hot tubs, steam baths, and saunas.
PREVENTING WORSENING OF LYMPHEDEMA
If you already have lymphedema, in addition to the measures listed above, there are things you can do to help keep it from getting worse over time. Below are the most important things you can do.
●To limit swelling:
•Do not wear clothing that restricts flow to and from the limb, and avoid activities that could interfere with lymph flow (eg, using a pelvic harness for rock climbing could constrict flow from the lower limb). Your doctor will prescribe special custom compression sleeves or hosiery and these should be worn as instructed.
•Keep your weight under control – Excessive weight gain or being overweight can worsen lymphedema and may limit the effectiveness of compression garments.
•Do not let your arm hang at your side for long periods of time without moving it; if your leg is affected, avoid standing for long periods. Elevate the limb when possible.
●Try to do some exercise and weight training – These activities can reduce of the severity of lymphedema, improve overall fitness, and help with weight control.
●If one of your arms is affected, avoid blood draws, intravenous (IV) lines, injections, and acupuncture on that arm, if at all possible. In addition, avoid continuous blood pressure monitoring on the affected arm. Blood pressure can be taken in the opposite arm, or if both arms are affected, in one of your legs.
●Contact your doctor or nurse if the affected arm or leg develops a rash, becomes red, blistered, painful, or warm to the touch, or if you get a fever (temperature greater than 100.4ºF or 38ºC). These symptoms could signal a possible infection that could cause the beginning or worsening of lymphedema.
If you notice symptoms of lymphedema, contact your doctor or nurse. Other causes of limb swelling, such as deep vein thrombosis or cancer recurrence, need to be excluded before lymphedema therapy can begin. There is no cure for lymphedema once it is firmly established. The main goals of treatment are to control swelling, relieve symptoms, and prevent the swelling from worsening over time. A therapy program that combines massage, skin care, exercise, and compression garments (compression bandages or a lymphedema sleeve or stocking) is recommended. Rarely, devices that forcefully compress the affected limb are used.
Treatment should begin as soon as possible. A healthcare provider or program with expertise in treating lymphedema can be especially helpful.
IMPACT OF LYMPHEDEMA
While lymphedema is usually not a life-threatening condition, it can have a major impact on your quality of life. A change in how your limb looks can be distressing as well as painful.
●After breast cancer surgery, having a swollen or misshapen arm may increase the worry about how it looks.
●If lymphedema affects the ability to use your arm or leg, this can affect your quality of life, particularly if it is your dominant arm (eg, right arm if you are right-handed).
●Lymphedema can reduce tissue healing and occasionally causes chronic pain. For these reasons, prevention and early treatment of lymphedema are recommended.
●The limb with lymphedema can develop cellulitis, a skin infection that requires antibiotics and possible hospitalization.
If you develop lymphedema many years after surgery or have worsening lymphedema, contact your doctor or nurse immediately.
WHERE TO GET MORE INFORMATION
Your healthcare provider is the best source of information for questions and concerns related to your medical problem.
This article will be updated as needed on our web site (www.uptodate.com/patients). Related topics for patients, as well as selected articles written for healthcare professionals, are also available. Some of the most relevant are listed below.
Patient level information — UpToDate offers two types of patient education materials.
The Basics — The Basics patient education pieces answer the four or five key questions a patient might have about a given condition. These articles are best for patients who want a general overview and who prefer short, easy-to-read materials.
Beyond the basics — Beyond the Basics patient education pieces are longer, more sophisticated, and more detailed. These articles are best for patients who want in-depth information and are comfortable with some medical jargon.

Professional level information — Professional level articles are designed to keep doctors and other health professionals up-to-date on the latest medical findings. These articles are thorough, long, and complex, and they contain multiple references to the research on which they are based. Professional level articles are best for people who are comfortable with a lot of medical terminology and who want to read the same materials their doctors are reading.
