What lymphoedema is
Lymphoedema is chronic swelling caused by impaired lymphatic drainage, allowing protein-rich fluid to accumulate in the tissues.
The lymphatic system runs alongside the veins. Its job is to collect the protein and fluid that leaks out of the small blood vessels into the tissues every day, and return it to the bloodstream through a network of fine vessels and lymph nodes.
When that drainage system is damaged or absent — from surgery, radiation, infection, or rarely a congenital problem — the fluid cannot drain normally. It builds up in the tissues, and over time it changes them: first soft and pitting, then firmer and fibrotic, then sometimes nodular and severely deformed.
Lymphoedema is different from other causes of swelling in three important ways:
- The fluid is protein-rich, not just water — so it triggers tissue changes over time
- It usually does not respond meaningfully to diuretics (those treat water, not the lymphatic problem)
- It is usually chronic and can progress if untreated, but with early recognition and proper management, most people can control swelling and maintain good quality of life
The good news: with early recognition, accredited therapy, and consistent self-management, most patients can control the swelling, prevent progression, and avoid the severe stages.
Primary vs secondary lymphoedema
Most lymphoedema is secondary — acquired from something that damages the lymphatic system. Primary lymphoedema is rare and usually genetic.
Primary lymphoedema (rare)
Genetic abnormality of lymphatic vessel development.
- Congenital — present from birth or appearing in early childhood (sometimes called Milroy disease)
- Early-onset primary — typically appears around puberty, more common in girls (sometimes called Meige disease)
- Late-onset primary — usually after age 35
Secondary lymphoedema (common)
- Cancer treatment — in Australia, one of the most common recognised causes. Breast cancer treatment commonly causes arm lymphoedema. Pelvic lymph node surgery or radiation for gynaecological, prostate, bladder, colorectal, or melanoma treatment commonly causes lower-limb lymphoedema.
- Chronic infection — recurrent cellulitis. Worldwide, filariasis is a major cause, but it is uncommon in people who have lived only in Australia.
- Trauma — major leg injury, burns, or extensive surgery
- Chronic venous insufficiency — long-standing CVI can secondarily impair lymphatic drainage (phlebolymphoedema)
- Obesity — severe obesity can cause obesity-induced lymphoedema
Lymphoedema after cancer treatment
Cancer-related lymphoedema can appear soon after treatment or many years later. It may follow lymph node removal, sentinel node biopsy, radiotherapy, or a combination of treatments. Breast cancer treatment commonly affects the arm, while pelvic surgery or radiation can cause leg or genital lymphoedema. Risk increases with the number of nodes removed, the extent of radiation, post-operative complications such as cellulitis, and being overweight. Early recognition allows early management, which is the single most effective way to prevent progression.
Symptoms and the Stemmer sign
Lymphoedema often starts subtly — a sense of heaviness, a ring or watch feeling tighter, a sleeve not fitting the same way. The Stemmer sign is the most useful clinical clue.
Common symptoms:
- A feeling of heaviness, fullness or tightness in the affected limb
- Visible swelling, often involving the back of the hand or foot (which distinguishes lymphoedema from venous oedema)
- Reduced range of motion or difficulty with fine movements
- Skin changes over time — thickening, dryness, a "peau d'orange" (orange-peel) texture in advanced cases
- Recurrent cellulitis is common in established lymphoedema and should raise suspicion, especially when swelling is chronic or asymmetric
- In late stages: fibrosis, nodular skin changes, and significant limb deformity
Stages of lymphoedema
Lymphoedema is staged 0 to 3 by the International Society of Lymphology. The staging matters because treatment effectiveness depends on how early it's caught.
| Stage | What it looks like | What it means |
|---|---|---|
| Stage 0 latent |
Lymphatic drainage is impaired, but there is no visible swelling. The patient may notice mild heaviness or tightness intermittently. | Can persist for months or years before progressing. Critical window for prevention strategies in high-risk patients. |
| Stage 1 reversible |
Visible swelling that improves with elevation overnight. Pitting on pressure. No skin changes. | Usually responds well to treatment. |
| Stage 2 irreversible |
Swelling no longer fully resolves with elevation. Pitting becomes less prominent as the tissue fibroses. Skin starts to thicken. | Active treatment can still significantly improve the situation. |
| Stage 3 severe advanced |
Severe non-pitting swelling. Marked skin changes — thickening, fibrosis, nodular changes, hyperkeratosis. Recurrent cellulitis common. | Sometimes called lymphostatic elephantiasis. Treatment is more difficult but still meaningful — debulking and intensive therapy can help. |
How lymphoedema is diagnosed
Lymphoedema is largely a clinical diagnosis. Imaging is reserved for uncertain cases or before surgical planning.
For most patients, lymphoedema is diagnosed at the bedside by combining:
- A relevant history — cancer treatment, injury, family history
- Examination — Stemmer sign, distribution of swelling, skin texture
- Exclusion of other causes — heart failure, kidney disease, venous insufficiency
When imaging is used:
- Lymphoscintigraphy — the traditional reference imaging test, showing lymphatic flow with a radioactive tracer. Used when the diagnosis is uncertain or before surgical planning.
- Duplex ultrasound — often used when one leg is swollen, to exclude DVT or venous reflux (see our guide to chronic venous insufficiency)
- MRI lymphangiography — sometimes used in specialised centres
- ICG (indocyanine green) lymphography — increasingly used in centres performing supermicrosurgery
Blood tests are not used to diagnose lymphoedema itself, but are sometimes ordered to exclude other causes (kidney, liver, thyroid, heart failure).
Treatment — what actually works
Lymphoedema cannot be cured, but it can be controlled. The cornerstone is Complete Decongestive Therapy (CDT) delivered by an accredited lymphoedema therapist.
Complete Decongestive Therapy (CDT)
The cornerstone treatmentA structured, two-phase program delivered by an accredited lymphoedema therapist — usually a physiotherapist, occupational therapist, nurse, or other clinician with recognised lymphoedema training and ALA accreditation.
- Phase 1 — intensive
- Typically 2–6 weeks. Manual lymphatic drainage (MLD), multilayer compression bandaging, skin care, and exercises designed to promote lymphatic drainage.
- Phase 2 — maintenance
- Lifelong. Compression garments (custom-fitted; usually need regular replacement, often around every 6 months, because they lose elasticity), self-MLD techniques, daily skin care, exercise programs, and periodic review with the therapist.
Treatment hierarchy
First-line for everyone:
- Complete Decongestive Therapy with an accredited lymphoedema therapist
- Custom-fitted compression garments
- Daily skin care to prevent cellulitis
- Regular exercise — strongly encouraged (see callout below)
- Weight management
Adjunctive options:
- Intermittent pneumatic compression pumps — useful at home, adjunct to CDT
- Low-level laser therapy — may help selected patients with fibrotic lymphoedema, but it is an adjunct rather than core treatment
Surgical options (specialised centres only):
- Liposuction (Brorson technique) — particularly effective for late-stage non-pitting fibrotic lymphoedema
- Lymphaticovenous anastomosis (LVA) — supermicrosurgery joining tiny lymphatic vessels to small veins
- Vascularised lymph node transfer (VLNT) — transplanting healthy lymph nodes from another site
These procedures are performed in specialised lymphoedema or reconstructive microsurgery centres. They are considered only after careful assessment and are not suitable for every patient. They are not "cures" but can reduce limb volume substantially in selected patients.
Lipo-lymphoedema (briefly)
Long-standing lipoedema can progress to secondary lymphoedema — a condition called lipo-lymphoedema. Both are present together, and management combines elements of each.
Lipoedema is a disorder of fat distribution that overwhelmingly affects women. In longstanding or severe cases, the mechanical and inflammatory effects of the fat tissue can secondarily damage lymphatic drainage, producing features of both conditions in the same limb.
Recognition is important because:
- The treatment combines lipoedema-specific approaches (potentially including liposuction) with lymphoedema management
- Diagnosis is sometimes delayed because lipo-lymphoedema can look like obesity
See our dedicated lipoedema guide for full coverage — diagnosis, characteristic features, and treatment.
When your GP sends you to a cardiologist — but it's lymphoedema
A small but consistent group of patients arrive at cardiology with swollen legs that have been assumed to be cardiac. The story is similar: bilateral swelling, no clear cardiac history, and a GP doing the right thing by excluding heart failure before assuming the swelling is lymphatic. The cardiac workup is normal — and the diagnosis turns out to be lymphoedema.
The pattern that should make a cardiologist (or a GP referring to one) reconsider:
- Echo is normal
- BNP or NT-proBNP is normal or only mildly elevated
- JVP is normal
- No orthopnoea or paroxysmal nocturnal dyspnoea
- Swelling involves the toes and dorsum of the foot
- Swelling is often non-pitting in later stages, but may be pitting early — do not exclude lymphoedema because it pits
- Stemmer sign is positive
- There is a relevant history — previous pelvic surgery, radiation, recurrent cellulitis, or a known cancer treatment
When this pattern is present, the next step is not more cardiac investigation, but referral to an accredited lymphoedema therapist for assessment and Complete Decongestive Therapy. A cardiologist's involvement is to confirm the heart is not the cause and to point the patient toward the right pathway.
When both are present
Lymphoedema and heart failure can coexist, particularly in older patients. The combination can be tricky: heart failure may make lymphoedema look worse, and lymphoedema may make heart failure seem more advanced than it is. When both are suspected, an echocardiogram, BNP, and Stemmer assessment together usually clarify the picture.
Lymphoedema care in Australia
Australia has a network of accredited lymphoedema therapists and partial government subsidies in several states. The care system is fragmented but the resources exist.
Finding an accredited therapist
The Australasian Lymphology Association (ALA) maintains the National Lymphoedema Practitioners Register (NLPR) — a searchable directory of ALA Accredited Lymphoedema Practitioners. Accreditation requires postgraduate training in lymphoedema and is the standard for Complete Decongestive Therapy in Australia. Accredited practitioners may be physiotherapists, occupational therapists, nurses, doctors, or massage therapists with recognised lymphoedema training.

Garment subsidies
Compression garments are essential for ongoing management but are not subsidised by Medicare. Some Australian states and territories run government subsidy schemes (for example, EnableNSW in New South Wales, the Statewide Equipment Program in Victoria, and the South Australian Lymphoedema Compression Garment Subsidy Scheme). Schemes vary widely between states, change over time, and have different eligibility criteria, co-payments, and exclusions — some states do not run a subsidy scheme at all.
Because these arrangements change, the most reliable, up-to-date source is the Australasian Lymphology Association, which maintains a current list of state and territory subsidy schemes. Private health insurance may also provide rebates for garments — check your individual policy. Out of pocket, garments typically cost A$200–500 each and usually need regular replacement (often around every 6 months) because they lose elasticity.
NDIS
For Australians under 65 with permanent and significant lymphoedema affecting function, NDIS funding may cover therapy, garments, and equipment. Eligibility is determined by the NDIA based on functional impact, not diagnosis alone. People who acquire lymphoedema after age 65 may need to explore My Aged Care or state-based supports rather than NDIS.
Medicare
Medicare does not specifically cover lymphoedema therapy. Limited subsidised allied health visits may be available through a GP-arranged chronic condition management plan — these arrangements change periodically and your GP can advise on what currently applies. The number of subsidised visits is generally modest and rarely covers the full cost or frequency of lymphoedema care.

Frequently asked questions
Is lymphoedema curable?
No, lymphoedema cannot be cured — but it can be controlled. With early recognition, Complete Decongestive Therapy, and consistent compression and self-management, most people maintain a good quality of life and prevent progression to the severe stages.
Will lymphoedema come back if I stop wearing my garment?
Swelling often worsens again if compression is stopped. Compression is part of long-term management for most people with established lymphoedema. After successful intensive therapy, some patients can reduce garment use, but most need to continue some form of compression long-term, particularly during travel, heat, or prolonged standing.
Can I fly with lymphoedema?
Yes, but with planning. Wear your compression garment throughout the flight (some patients use a higher compression class than usual for flying). Stay well hydrated and move around regularly. Most lymphoedema therapists recommend continuing your usual exercises before and after the flight.
Why do I keep getting cellulitis?
Lymphoedematous tissue is protein-rich and has impaired immune surveillance, making it more vulnerable to bacterial infection. Cellulitis can also further damage the lymphatics, creating a worsening cycle. Daily skin care and prompt treatment of any cuts or breaks are essential. Repeated cellulitis should prompt a discussion with your doctor about prevention, including skin care and, in selected cases, antibiotic prophylaxis.
Is lymphoedema covered by Medicare or NDIS?
Partially. Medicare does not specifically cover lymphoedema therapy, but limited subsidised allied health visits may be available through a GP-arranged chronic condition management plan — your GP can advise on what currently applies. NDIS may fund therapy and garments for eligible patients under 65 with significant functional impact. State-based garment subsidy schemes exist in several states but vary widely. Private health insurance may also provide rebates.
Should I avoid blood pressure measurements on my affected arm?
This advice has become more nuanced. The historical recommendation was to avoid blood pressure, blood draws, and injections in the affected arm after breast cancer surgery. More recent evidence suggests these activities do not meaningfully increase lymphoedema risk in most patients. However, many therapists still recommend using the unaffected arm where practical, particularly in the first 2 years after treatment.
Can lymphoedema cause shortness of breath?
Lymphoedema itself does not usually cause breathlessness. New breathlessness should prompt assessment for another cause, such as heart failure, lung disease, anaemia or pulmonary embolism. A cardiology assessment is appropriate.
Is lymphoedema dangerous?
Lymphoedema is not directly life-threatening, but the morbidity is significant — recurrent cellulitis, reduced limb function, skin complications, and substantial impact on quality of life. Very rarely, long-standing severe lymphoedema has been associated with angiosarcoma, a cancer called Stewart-Treves syndrome. This is uncommon, but persistent new lumps, bleeding, or rapidly changing skin lesions should be assessed.
