AskTari: Hi Tari – I have a student with metastatic breast cancer who has lymphedema in her breast from prior treatment. I don’t recall seeing specific information on breast lymphedema — most of the resources focus on the limbs. Are there any particular precautions or considerations for practicing yoga with breast lymphedema specifically?Thank you for any info!
Great question, Pam — and an important one. You’re right that most lymphedema resources focus on the arms and legs, because that’s where it’s most visible and most functionally limiting. But lymphedema can occur anywhere in the body, including the remaining breast tissue, the chest wall, and the back. Lymphedema in those areas is referred to as Truncal Lymphedema. It’s one of those side effects that falls into what I call the “unanticipated” category — less talked about, but very real.
Here’s what teachers and survivors need to understand.
Why breast lymphedema happens
When lymph nodes are removed — wherever they are — the lymphatic system is permanently altered. Lymph fluid needs to find new pathways to reach the thoracic duct. Until it does, fluid can collect in unexpected places. If the removed nodes were located deep in the center of the chest rather than near the underarm, breast tissue is particularly vulnerable to fluid buildup.
For a student with metastatic breast cancer and prior treatments, there’s an added layer. Lymphedema can emerge or worsen years after the original surgery — triggered by factors like weight changes, reduced activity, infection, or the progression of disease. It is a sign that the lymphatic system is struggling to do its best with a compromised map.
The core principle: keep lymph moving in the right direction
Think of yoga as the muscle that keeps lymph flowing — the way the heart keeps blood moving. The lymphatic system has no pump of its own. Breath, movement, and gravity do that work. Which means yoga done well is genuinely therapeutic here. But some postures, if not taught carefully, can obstruct that flow rather than support it.
Direction is everything.
What to watch for and how to modify
Forward folds and prone postures: Rounding the spine compresses the chest and can obstruct lymph flow in that central area. In any forward fold — and in prone poses like cobra — use props to keep the chest lifted and the spine long. Block towers at the right height for your student’s flexibility ensure the spine stays elongated and the chest stays open. That’s not just a comfort modification; it’s a lymphatic one.
Arms overhead: Full overhead arm extension in standing or seated poses asks lymph to travel with gravity. For a student with breast lymphedema, modify with cactus arms instead — elbows bent, arms wide — which provides a more gradual flow back toward the center of the body where the thoracic duct sits.
Backbends: Some backbends will direct lymph flow toward the chest, which in this case you want to approach with care. Supported bridge, for example, may not be the best choice. Supported fish or elevated cobbler — where the chest is gently and passively opened with props — are better options.
Your best tool: the exhale
Start every practice with pranayama. The exhale is a natural internal assist to lymphatic flow — it creates pressure changes in the chest that help move lymph toward the thoracic duct. Matching the exhale to movement in twists, side bends, and modified forward folding works like a gentle internal lymphatic massage. This is especially valuable in restorative poses, where a focused breath practice gives your student something active she can do from the inside — on her own, at home, whenever she needs it.
Teaching her to use breath this way is one of the most practical gifts you can offer. It gives her agency over a side effect that can feel completely out of her control.
