About Lymphedema 

What is lymphedema? 

Lymphedema is when fluid builds up in your body’s tissues, causing swelling. This can happen after treatments like radiation or surgery, or from injuries like burns or infections. The lymphatic system, which is like your blood vessels but carries lymph fluid instead of blood, can get damaged during these treatments. This damage can cause lymph fluid to build up in the treated area, leading to swelling called lymphedema.

Although lymphedema can be treated, there is no cure. It is important to pay close attention to symptoms and seek medical treatment early on. Lymphedema can be managed with the help of a specialized lymphedema therapist.  

What are the symptoms of lymphedema? 

• Swelling 

• Heaviness 

• Tightness  

• Firmness       

• Numbness or tingling  

• Stiffness in the arms, legs, or other affected body parts 

• Pain or aching 

How can I reduce the risk of lymphedema? 

• Maintain a healthy body weight:

  • Losing body fat can help reduce lymphedema. 

• Protect your skin:

  • Take care of your skin to avoid infections.  Clean cuts with soap and water. Use antibacterial ointment for up to a week.

  • Call your medical team if a wound doesn't heal.

• Use your unaffected arm:

  • When possible, use your unaffected arm for blood pressure readings, blood draws, injections, and vaccinations. 

  • If both arms are affected, use the arm with fewer lymph nodes removed. 

• Exercise:

  • Movement helps reduce the risk of fluid buildup. 

Physical Activity and Exercise 

• Exercise does not cause lymphedema. In fact, it can help with prevention. It’s also good for your overall recovery.

• Aerobic and resistive exercise help promote the movement of lymph fluid.

• Gradually increase the resistance and duration of your exercises.  

• It is important to wear loose-fitting clothes and stay hydrated.

• If you have lymphedema, support the affected area with a compression garment. 

How does NYU Langone Health treat Lymphedema? 

• Complete Decongestive Therapy (CDT):  This treatment reduces swelling, prevents the condition from getting worse, and lowers the risk of infection. CDT includes: 

  • Manual Lymphatic Drainage 

  • Exercises 

  • Compression garments (like bandages and compression sleeves) 

  • Skin care 

• At NYU Perlmutter Cancer Center (PCC) and Rusk Rehabilitation, licensed clinical practitioners with special training perform CDT and other lymphedema treatments. Your medical team will help to coordinate these therapy services.
