Lymphoedema After Breast Cancer Treatment : Early Signs & How Physiotherapy Can Help

A ProVital Physiotherapy Guide
Have you noticed that one arm feels heavier than the other? Perhaps your sleeve feels tighter, your hand looks swollen, or your arm feels full and uncomfortable even without much activity.
After breast cancer treatment, these changes may raise concerns. One possible cause is lymphoedema, a condition that occurs when the lymphatic system cannot drain excess fluid effectively.
Not everyone develops lymphoedema after breast cancer treatment, but recognising the early signs and seeking appropriate assessment can help ensure timely care.
What Is Lymphoedema?
The lymphatic system helps transport fluid and supports immune function. When lymphatic drainage is impaired, fluid can accumulate in the tissues, causing swelling known as lymphoedema.
Following breast cancer treatment, lymphoedema may affect the arm, hand, breast or chest on the treated side. It can develop after lymph node surgery or radiotherapy, and symptoms may appear months or even years later.

What Are the Early Signs of Lymphoedema?
Early symptoms may be subtle and can include:
Heaviness: Your arm feels heavier or more tired than usual.
Tightness: Your sleeve, watch or rings feel tighter on the affected side.
Swelling: Puffiness appears around the hand, fingers or arm.
Fullness or discomfort: Your arm, breast or chest feels stretched or uncomfortable.
Reduced movement: Tightness or swelling makes it harder to lift your arm or perform daily activities.
These symptoms do not necessarily mean you have lymphoedema. Other conditions can cause similar changes, so professional assessment is important.
Does Everyone Develop Lymphoedema After Lymph Node Surgery?
No. Lymph node removal and radiotherapy can increase the risk, but not everyone develops lymphoedema. Your risk depends on factors such as the extent of surgery, treatment received and individual health circumstances.
Understanding your risk and following your cancer care team's monitoring advice can help with early detection.
How Can Physiotherapy Help?
Lymphoedema management should be tailored to the patient's condition and guided by an appropriately trained healthcare professional. Depending on the assessment, treatment may include:
Exercise and movement: Gentle movement and progressive exercise help maintain mobility, strength and physical function.
Compression: Suitable compression garments may help manage swelling when recommended by a trained practitioner.
Skin care: Keeping the skin clean, moisturised and protected helps reduce skin problems and infection risk.
Specialist lymphoedema treatment: A structured programme may combine compression, exercise, skin care and manual lymphatic drainage when appropriate.
Manual lymphatic drainage is not a stand-alone cure. Treatment should be individualised and delivered by a suitably trained practitioner.
Should I Stop Exercising If I Have Lymphoedema?
Not necessarily. Appropriately prescribed exercise is generally an important part of lymphoedema management. Gradual resistance training can also be suitable for many patients when introduced with appropriate guidance.
Start at a level that matches your ability and increase activity gradually. If swelling or discomfort increases significantly or new symptoms develop, seek professional advice.
When Should I Seek Medical Attention?
New swelling after breast cancer treatment should be assessed by a healthcare professional, particularly if it develops suddenly or is accompanied by pain, redness or warmth.
Fever, chills or rapidly worsening redness may indicate an infection requiring urgent medical attention. Sudden arm swelling or pain also requires prompt assessment to rule out a blood clot.
Do not assume that every episode of swelling is lymphoedema.
Living Well After Breast Cancer Treatment
Recovery often continues long after surgery and the final treatment appointment. Understanding your symptoms, staying appropriately active and seeking the right support can help you manage changes with greater confidence.
At ProVital Physiotherapy Centre, we believe rehabilitation should be based on each patient's needs rather than a standard programme.
If you notice swelling or heaviness after breast cancer treatment, begin with a medical assessment. Your healthcare team can help identify the cause and guide you towards appropriate lymphoedema care.
