Lymphoedema exercises after cancer: what is safe?

For most people, yes. The evidence, mostly from people with arm swelling after breast cancer, shows exercise is safe with lymphoedema, and the NHS lists regular exercise among the main ways to keep the swelling under control [1]. In a breast cancer trial, slowly built-up weight lifting did not increase arm swelling and led to fewer flare-ups [2]. Start gently, wear your compression garment if you have one, and get assessed before lifting weights.

What is lymphoedema and who gets it after cancer?

Lymphoedema is long-term swelling caused by a build-up of lymph fluid when the lymphatic system is not working properly [1][3]. After cancer it usually follows surgery to remove lymph nodes, radiotherapy to an area with lymph nodes, or both, and it can appear months or even years after treatment [4].

Cancer Research UK lists the cancers where it is more likely: breast, vulval, cervical, womb, penile, prostate and bladder cancer, lymphoma, melanoma and head and neck cancer [3]. Macmillan adds anal, testicular and rectal cancers, and notes that cancer spreading to the lymph nodes, or a tumour pressing on lymph vessels, can also cause it [4].

It mostly affects an arm or a leg, but it can also develop in the breast, chest, back, abdomen, genitals, head, neck or face [3]. Typical signs are swelling, a heavy feeling, difficulty moving the limb and repeated skin infections [1]. There is no cure, but the NHS says symptoms can usually be managed with compression garments, regular exercise, skin care and specialised massage [1].

Can exercise make lymphoedema worse?

The evidence says no for most people. Cancer Research UK states that exercise "doesn't cause or worsen lymphoedema" and may improve quality of life [5].

When your muscles contract, they push lymph along the lymphatic vessels [5]. A Cochrane review of 24 trials with 2,132 participants after breast cancer found "no evidence of increased risk of lymphedema from exercise at any time point" [6]. Cancer Research UK also says any type of exercise and movement can help lower the risk of developing lymphoedema in the first place [7].

One honest caveat. Most of the research is in women with arm lymphoedema after breast cancer. The international exercise guidelines for cancer survivors (the ACSM roundtable, 2019) say the effects seen in breast cancer "may not translate" to lymphoedema after head and neck, bladder, melanoma, gynaecological or other cancers [8]. Moving regularly is still the advice for leg and head and neck lymphoedema [1][5]; let a specialist set the pace for anything harder than everyday activity.

Is weight training safe with lymphoedema?

For arm lymphoedema after breast cancer, yes, when it is supervised and built up slowly. Two trials called "Physical Activity and Lymphedema" (PAL; US spelling) found that slowly progressive weight lifting did not increase arm swelling in women who already had lymphoedema, and did not increase the risk of new lymphoedema in women who had had lymph nodes removed [2][9]. In the first trial, flare-ups were less common in the lifting group (14% vs 29%) [2].

The ACSM roundtable turns this into practical guidance: for arm lymphoedema after breast cancer, a progressive programme for the large muscle groups, two to three times a week, starting low and progressing slowly, is safe when supervised by a trained exercise professional [8]. It adds that there is not enough evidence to say whether starting weights unsupervised is safe, and that every programme it reviewed began with supervision [8]. For the full trial results and arm and shoulder recovery after surgery, see exercise after breast cancer.

Leg lymphoedema and other cancers. The evidence is much thinner. The ACSM roundtable limited its lymphoedema advice to arm swelling after breast cancer [8], so it gives no weight-training advice for swelling in a leg, the groin, the abdomen or the head and neck. That is a gap in the research, not proof of harm. Cancer Research UK still includes strength training and leg exercises such as heel raises [5]; ask your lymphoedema specialist to agree a starting point, and build up with a professional who can watch how your swelling responds.

Should you wear compression when exercising?

If you have been given a compression garment, UK cancer charities advise wearing it when you exercise. Macmillan says you usually need to wear it during exercise, and Cancer Research UK advises wearing your sleeve or leg garment if you have one [10][5].

The PAL trial required everyone to wear a well-fitted compression garment while lifting [2]. The ACSM roundtable notes that there is not yet enough evidence to support or refute this advice for arm lymphoedema after breast cancer [8], so follow what your own lymphoedema specialist tells you. If your garment is uncomfortable when you exercise, talk to your specialist [10].

What lymphoedema exercises help arms and legs?

Gentle, regular movement of the swollen limb, done slowly, alongside everyday activity such as walking or swimming. Cancer Research UK suggests doing some exercise every day, starting gently and building up slowly [5].

These are examples, not a programme for you; your lymphoedema service will show you which exercises suit your swelling.

• Deep breathing first. Cancer Research UK describes slow, deep breaths in through your nose, feeling your abdomen rise under your hand [5].
• Arm exercises. Breast Cancer Now's arm and shoulder exercises are done three or four times a day, "slowly and gently", because fast movements do not let lymph fluid drain properly [11]. A seated example from Cancer Research UK: touch your knees, then your shoulders, then lift your arms as far as you can without pain [5].
• Leg exercises. Cancer Research UK suggests marching on the spot or sitting down, heel raises to squeeze the calf muscles, and ankle circles in both directions [5]. The British Lymphology Society points out that everyday movement such as walking and heel raises helps the lymphatic system too [12].
• Resting position. With arm lymphoedema, rest the arm on a cushion at a comfortable height; with leg lymphoedema, try not to sit with your legs down for long periods [5]. Macmillan suggests not leaving the limb in one position for too long [10].
• Whole-body activity. Walking, swimming, aqua aerobics, cycling, dancing, yoga, tai chi and Pilates are all suggested [5]. Macmillan notes that swimming and aqua aerobics put less strain on your joints if you have joint problems [10].
• Before you swim or do aqua aerobics. Wait until your wounds have completely healed, to avoid infection [22]. Do not swim with a central line or PICC line, because of the risk of infection [21], and ask your team first if you are having chemotherapy [22]. During radiotherapy, and until any skin reaction has gone, avoid swimming, because pool chemicals can irritate your skin; ask your radiotherapy team when you can start again [21][22].
• Strength work. Cancer Research UK includes strength training [5]; build it up with a professional, as in the PAL trials [2][8]. Avoid static holds such as the plank, where muscles work without your body moving [21].

Weight matters as well: Cancer Research UK says being overweight can increase the risk of lymphoedema because of extra pressure on the lymphatic system [7].

When should you stop exercising and get help?

Stop and contact your lymphoedema specialist if the swelling changes or gets worse during or after exercise [5][10]. Skin that is red, hot, painful or more swollen, especially with a temperature or feeling unwell, may be cellulitis, an infection that needs urgent help [13][14].

People with lymphoedema are more prone to cellulitis. Cancer Research UK lists these signs [13]:

• a temperature of 37.5°C or higher, or below 36°C
• redness of the skin, which may look darker or purple on brown or black skin
• heat, pain or swelling
• flu-like symptoms

Who to contact:

• Your 24-hour advice line, straight away, if you think you have an infection [13].
• An urgent GP appointment or NHS 111 if your skin is painful, hot and swollen [14].
• 999 or A&E if you have cellulitis with a very high temperature, a fast heartbeat or breathing, purple patches on the skin, confusion, cold or clammy skin, or dizziness or fainting [14].

Macmillan advises not exercising while you have a skin infection [10].

Ask your specialist when to restart exercise after an infection.

Who should you see?

Your NHS lymphoedema service comes first. Your cancer doctor, specialist nurse or GP can refer you [1][4]. The team may include specialist lymphoedema nurses, physiotherapists and occupational therapists [4]. If you have not been referred to a lymphoedema clinic, the Lymphoedema Support Network, a national patient charity, can tell you where your nearest one is [15]; the British Lymphology Society also has a directory of services [12].

Physiotherapists are regulated by the Health and Care Professions Council (HCPC), and physiotherapist is a title protected by law [18]. They are often part of lymphoedema care [4].

Clinical exercise physiologists (CEPs) are university-qualified professionals who specialise in prescribing and delivering evidence-based exercise for acute, chronic and complex conditions [16]. CEPs can join a voluntary register held by the Academy for Healthcare Science, which is accredited by the Professional Standards Authority [17]. Once your lymphoedema has been assessed, a CEP can build the kind of progressive, supervised strength programme tested in the PAL trials, and fit it around fatigue, bone health and the rest of your treatment. CEPs work alongside physiotherapists and your lymphoedema team rather than replacing them.

Level 4 cancer rehabilitation instructors, whom Macmillan calls cancer exercise specialists, are fitness instructors qualified to help people with cancer exercise safely, and might work in a gym or local leisure centre [19].

To see how these roles fit together, read who is on a cancer rehabilitation team, or start at cancer rehabilitation in the UK.

Talk to your oncology team first

Cancer Research UK advises talking to your doctor or lymphoedema specialist before you start any exercise [5]. Check first, or start with supervision, if any of these apply:

• You have had lymph nodes removed or radiotherapy and want to start weights [8].
• You have new swelling that has not been assessed. Macmillan warns that swelling, aching and redness in an arm or leg can also be a sign of a blood clot: tell your doctor or nurse straight away, or call NHS 111 if you cannot reach them [4]. Call 999 or go to A&E if you also feel short of breath or have chest pain, because a clot can travel to the lungs [20].
• You have signs of a skin infection [10][13].
• You have recently had surgery, or have cancer in your bones. See exercise after cancer treatment and exercise with other cancers.
• You have had pelvic surgery or radiotherapy for prostate cancer: see exercise and prostate cancer.
