Swelling of the arm, known as lymphoedema, is a common and distressing consequence of breast cancer surgery, particularly when lymph nodes are removed. Manual lymphatic drainage (MLD) is a gentle, hands-on technique widely used to help manage it, and this large review set out to test how well it actually works.
The authors pooled 17 randomised controlled trials involving 1911 patients, examining whether MLD helps prevent lymphoedema and whether it reduces swelling and improves symptoms in people who already have it.
Breast cancer-related lymphoedema is one of the most common reasons people are referred for lymphatic drainage. A large review helps show where MLD genuinely helps and where expectations should be measured.
Light, rhythmic, skin-stretching strokes that follow the lymphatic pathways to encourage excess fluid to move away from the swollen arm.
MLD is typically used alongside compression, exercise and skin care, together known as Complete Decongestive Therapy, rather than on its own.
The evidence was encouraging for swelling, and more mixed for other outcomes.
Some evidence suggested MLD may reduce the risk of developing lymphoedema after breast cancer surgery, though this remains debated.
Adding MLD to standard care was associated with greater reductions in arm swelling volume in several trials.
Benefits for subjective symptoms such as heaviness, and for arm function, were less consistent across studies.
MLD is low-risk and well tolerated, making it a reasonable component of lymphoedema care.
Manual lymphatic drainage, used alongside compression and exercise, was associated with reduced arm swelling in breast cancer-related lymphoedema, with a possible role in prevention, though its effect on symptoms and function is less certain.
This supports MLD as a genuine, evidence-informed part of managing breast cancer-related swelling, best delivered within a broader plan that includes compression, movement and skin care, and in coordination with the person’s medical team.
It also encourages honest expectations. MLD can help move fluid and support comfort, but it is one part of a package, not a stand-alone cure, and results vary from person to person.
Directly supports MLD as a core technique for breast cancer-related swelling, delivered within Complete Decongestive Therapy.
Reinforces gentle, appropriate soft-tissue and scar work as part of recovery, always within scope and with medical clearance.
Of interest for supporting comfort and movement around the shoulder and arm alongside lymphatic care.
Limited direct relevance; included for completeness rather than treatment application.
The included trials varied in quality, in how MLD was delivered, and in how swelling was measured, which lowers certainty. Notably, some reviews, including a Cochrane review, have not found a clear added benefit of MLD within Complete Decongestive Therapy, so the evidence is genuinely mixed.
The honest reading is that MLD may help swelling volume and is safe, but it should be framed as part of a package. Please confirm the citation details and author list against the source before publishing.
Pooling 17 trials with 1911 patients, this review found MLD was associated with reduced arm swelling in breast cancer-related lymphoedema, with a possible preventive role, though effects on symptoms and function were less certain and some reviews find limited added benefit.
For lymphatic drainage practitioners, it supports MLD as a valued part of a broader plan, delivered with medical coordination and realistic expectations.
