Cynthia asked: Since my mastectomy and breast reconstruction with an implant, I haven’t been able to regain full strength and mobility in my right arm. My sister has done yoga for years and keeps encouraging me to start — she believes it will help. I’ve never done yoga before, and the implant makes me nervous about moving my arm too much. When is it safe to begin?
Tari answers:
Sooner than you might think — but your specific details matter, and they depend on what surgery you had.
Your sister’s yoga practice is her own. What’s appropriate for someone without surgical history or cancer-related side effects may not be appropriate for you. Yoga is not one-size-fits-all. Here’s how certain surgeries shape what safe practice looks like and when.
Before anything else
Regardless of surgery type: incisions should be healed and surgical drains removed before you begin. If you’re fewer than six weeks post-surgery, get clearance from your surgical team first. And find a teacher with oncology training — a standard 200-hour certification doesn’t cover post-surgical care. A qualified teacher will ask about your history before your first class. If they don’t, keep looking.
Mastectomy without reconstruction
Choosing not to reconstruct — whether that was your preference or your medical situation — is a legitimate path, and it comes with its own set of physical considerations that yoga teachers need to understand.
These patterns, if left unaddressed, can compound over time. The affected arm may get used less, weakening further while the stronger side compensates. Yoga can directly support recovery here: gradual, supported movement helps restore range of motion, counters protective posturing, and rebuilds the strength needed for daily function. But a teacher needs to understand your chest wall mobility, scar tissue, and any lymph node removal before designing a practice for you.
Implant reconstruction
Post-mastectomy implant reconstruction is not the same as cosmetic augmentation. With little remaining breast tissue to cushion the implant, the pectoral muscles and chest wall carry significant surgical impact. Restricted arm range of motion is expected, and scar tissue may limit how fully the arm extends. Some people also develop capsular contracture — hardening of scar tissue around the implant — which adds further tightness.
The instinct to protect the implant by limiting movement is understandable, but avoidance isn’t the answer. Gradual, adapted movement consistently supports better long-term recovery. A good oncology yoga teacher will help you increase range of motion incrementally — and keep your stronger arm from pulling ahead of your recovering one.
Flap reconstruction
Flap procedures (TRAM, DIEP, latissimus dorsi) involve two surgical sites. Abdominal flaps affect core strength and the integrity of the abdominal wall. The latissimus dorsi flap repositions back muscle to the chest, directly affecting shoulder and upper back mobility — and contributing to the same protective posturing pattern. Recovery for the donor site is its own consideration, and a yoga teacher needs to account for both.
A note for those with tissue expanders
If you’re currently in the tissue expansion phase — the period between mastectomy and final implant placement — yoga is still possible, and can be genuinely supportive during what is often an uncomfortable and drawn-out process. Breath work, gentle movement, and guided relaxation are all accessible and valuable right now.
That said, your practice will look different than it will after the exchange surgery. As the expander is gradually filled, the chest muscle and surrounding tissue are under active tension, and range of motion on the affected side may be more limited. Comfort levels can also shift around fill appointments.
Let your body lead, confirm with your surgical team what movement is appropriate during this phase, and work with a teacher who knows how to meet you where you are — not where you’ll be when the process is complete.
How much yoga, and what kind?
Current guidelines from the American Cancer Society and AICR recommend cancer survivors work toward at least 150 minutes of moderate activity per week, plus strength training twice a week. An adapted yoga practice can be part of reaching that goal. Two to three sessions per week is a reasonable starting point — consistency matters more than intensity, especially early on.
“Gentle” isn’t a guarantee of safe, and “active” isn’t a guarantee of risky. It comes down to how the practice is designed and who’s teaching it.
Find an oncology-trained teacher through the y4c directory — the largest in the world, with certified professionals in more than 30 countries.
I hope this helps you find a yoga teacher and class that allows you to thrive, as well as survive. Yoga can be a tool to help you reclaim your life during and after cancer. If used properly, yoga can also be a lifetime companion that will smooth out all the challenges of life, not just the ones we experience on the cancer journey. In the meantime, please send me more questions, share your findings and stay in touch.
Namaste,
Tari
