LYMPH•LOGISCH · Understand your symptoms
After breast cancer: when your arm or hand swells.
Does your arm feel heavy, your hand look fuller or your rings suddenly feel tighter? Lymphoedema may develop after lymph node surgery or radiotherapy. Early assessment and targeted care can often help control swelling.
Why can the arm or hand swell?
Lymphatic vessels return tissue fluid to the circulation. Removing underarm lymph nodes or damaging pathways through surgery or radiotherapy can reduce transport capacity. Fluid may then remain in the tissues. This can affect the arm, hand and fingers, and sometimes the breast or chest. It may develop soon after treatment or years later. Not everyone who has lymph nodes removed develops lymphoedema. [3]
Which early signs matter?
Heaviness or tightness can appear before visible swelling. Watches, sleeves or rings may feel tighter. The back of the hand, fingers or parts of the arm may look fuller, and changes may fluctuate during the day. Do not wait for the whole arm to become noticeably swollen. Assessment combines symptoms, tissue findings and circumference or volume measurements over time. Earlier baseline measurements can help. [3], [6]
Reducing swelling, then maintaining the result.
More pronounced swelling may first need an intensive reduction phase. Multilayer compression bandaging, movement, skin care and drainage where appropriate may be combined. Bandages are adjusted as volume changes. Once swelling is sufficiently reduced and stable, suitable compression garments are fitted. Maintenance combines garments, movement and self-care to preserve the result. Mild findings may sometimes be managed with appropriate garments without an intensive bandaging phase. [1], [2]
Does the hand need its own compression?
The arm and hand are assessed together. An arm sleeve alone does not suit every swelling pattern. Hand or finger involvement may require an additional hand garment, such as a fitted glove. Design, material and pressure are chosen individually, with movement and comfort in mind. New finger swelling, constriction, pain or numbness should prompt a timely fit review. [1]
What is the role of manual lymphatic drainage?
Gentle, targeted techniques aim to support fluid transport through available pathways. Use is guided by your findings and response. Drainage alone does not replace necessary compression. A large comparative trial in chronic arm lymphoedema found no clinically important added benefit over well-delivered compression, exercise, skin care and education. [4] This supports selecting each component deliberately and reviewing progress.
Can I use my arm and build strength?
Yes. Lymphoedema does not mean permanently resting the arm. Tailored activity and gradually progressed strength training can support function and quality of life. Loading is adapted to your starting point and tissue response. Skin and nail care and practical self-management also matter. You receive an individual exercise programme and learn how to recognise changes early. [2]
When is medical assessment needed first?
New or rapidly increasing swelling is not automatically lymphoedema. Other causes, including infection or a blood clot, may need to be excluded. Redness, warmth, pain or fever require immediate medical assessment. New lumps or unusual changes also belong with the treating team. Lymphological care can then be planned appropriately. [2], [3]
Research in context
What do the studies show?
How were the treatment components compared?
The 2022 EFforT-BCRL trial included 194 people with chronic unilateral arm lymphoedema. All received education, skin care, compression and exercise. Additional image-guided drainage, traditional drainage or sham treatment were compared. Excess arm and hand volume decreased in every group. Drainage did not add a clinically important benefit for volume or other measured outcomes such as function and quality of life. This concerns that addition in that patient group. Care therefore selects components according to findings, goals and progress rather than making a manual technique the sole focus. [4], [2]
What is new in compression research?
The randomised 2026 LYMphoNIGHT trial studied 56 patients after an intensive reduction phase. A specific night-compression system added to a daytime sleeve reduced excess arm volume more over three months than daytime compression alone. Some other outcomes and quality-of-life measures also improved. This was a small, product-specific trial, not a requirement for everyone to wear night compression. Any night garment is selected separately where appropriate: do not simply continue wearing a daytime sleeve overnight without advice. [5]
What does this mean for your care?
The NICE guideline updated in 2025 places compression at the start of management and supports physical activity. [2] Together with the trials, this supports an individual plan and follow-up measurements. The aim includes not only reduced circumference but also a mobile hand, less tightness and care that fits your daily life.
Looking at arm and hand together.
A tighter ring or unfamiliar heaviness can be a reason to look more closely. I assess arm and hand together so that less obvious changes are considered too. If decongestion is needed, we plan suitable compression and maintenance just as carefully afterwards. I want you to understand which steps are appropriate for your findings and how to put them into practice.
