It’s a few minutes before class. Tari Prinster, founder of yoga4cancer, is in the hallway outside the studio, moving from one student to the next. A regular arrives wearing a compression sleeve she didn’t have last month. Another student mentions, in about 90 seconds, a new chemo setback and a radiation appointment that means leaving class early. Three new faces have joined the group. One had a double mastectomy and 18 lymph nodes removed three weeks ago. Another is having a lumpectomy next week. A third stands quietly in street clothes, hoping to practice in the linen pants she wore to work.
From across the room, most of these students look like anyone else in a yoga class. That’s the point.
Cancer Is Mostly Invisible
When people picture someone with cancer, they often picture a bald head or a frail body. But those are effects of treatment, and not everyone has them. Many people in treatment, and most people after it, look just like everyone else on the mat.
What you can’t see is often what matters most for safety. Under a loose t-shirt, a student might have:
- A chemo port just under the skin of the chest. Direct pressure, such as lying face down or a strap pulled across the chest, can be uncomfortable or unsafe.
- Surgical drains from a recent surgery. People are generally advised to wait until drains are removed before starting yoga.
- A mastectomy, with or without reconstruction. Reconstruction can involve tissue from the abdomen (TRAM or DIEP flap) or the back (latissimus dorsi flap). This affects how the core, shoulder, and chest can move, sometimes for years.
- Missing lymph nodes. After nodes are removed from the underarm, groin, or pelvis, the risk of lymphedema is lifelong, even if the arm or leg looks completely normal today.
- Bone loss from hormone therapy or treatment-induced menopause. A deep, rounded forward fold can put real stress on a thinning spine.
- Neuropathy in the feet or hands from chemotherapy, which affects balance and grip in standing poses.
- Low blood counts during chemo, which affect energy and infection risk.
- Cancer that has spread to the bone, which changes what load and impact are safe.
None of these show from the front of the room.
Why Students Don’t Just Tell You
Teachers often assume a student will speak up if something matters. Usually, they don’t, and for good reasons.
They don’t know what YOU need to know. A student may tell you about their diagnosis but not think to mention the port, the reconstruction, or the 18 nodes. They don’t know those details change what you’d teach.
They don’t want to be treated as fragile. Most people with cancer aren’t looking to be coddled. Many want to feel like themselves again, and a yoga class can be one of the few places where they’re not a patient.
It’s personal. Sharing health details in front of a group, or writing them on a sign-in sheet, is a lot to ask.
It changes. Someone who was fine last week may have started a new treatment, developed a new side effect, or had a hard scan result since then.
Why “Any Injuries?” Isn’t Enough
Most yoga studios have some version of the same intake: a sign-in form, a waiver, and a quick “Any injuries I should know about?” before class.
That question works for a sore knee. It doesn’t work for cancer. A student who had lymph nodes removed doesn’t think of that as an injury. Someone on hormone therapy may not know their bones are thinning. And a written health questionnaire can feel like one more medical form, which is exactly what many people come to yoga to get away from.
Most yoga teacher trainings weren’t built to cover this. That’s not a failing of those trainings. They simply weren’t designed for students with cancer.
What a Good Intake Does
In the yoga4cancer method, intake is a short, private conversation before class, not a form. We call it Fast Facts. It’s built on a few ideas:
- Ask in person, one-on-one. A quiet word before class, not a question in front of the group.
- Ask in order. One answer leads naturally to the next. “I’m on chemo for stage 4 pancreatic cancer” answers several questions at once. “I had thyroid cancer” means your next question is when.
- Know what to listen for: cancer type, where they are in treatment, surgeries and reconstruction, ports or drains, lymphedema, neuropathy, dizziness, other non-cancer-related health conditions, and whether their doctor has cleared them to exercise.
- Ask again. Check in with returning students too. Treatment and side effects change week to week.
- Don’t keep medical records. You need the information to teach that day’s class safely, not to store it.
This conversation isn’t an assessment. Yoga teachers don’t diagnose and don’t give medical advice. The goal is to understand enough to teach safely, and to know when to suggest a student check in with their care team.

Teacher Takeaways
- You can’t tell what a student is managing by looking at them.
- Students often don’t know which details matter, so it’s the teacher’s job to ask.
- “Any injuries?” won’t surface ports, missing lymph nodes, bone loss, or neuropathy.
- Keep intake private, conversational, and repeated as things change.
- Gather context to teach safely. Leave medical questions to the care team.

FAQ
What should I ask a new yoga student who has cancer? Ask privately and conversationally about their cancer type, when they are in treatment, any surgeries or reconstruction, ports or drains, and side effects like lymphedema, neuropathy, or dizziness. Also ask about other health conditions and whether their doctor has cleared them to exercise.
Should students with cancer fill out a written health form for yoga class? yoga4cancer recommends a verbal intake instead. Written medical forms can feel clinical, and storing health information creates privacy and liability risks a yoga teacher doesn’t need. Standard studio waivers are separate from this.
Can someone with a chemo port do yoga? Yes, with awareness. Avoid direct pressure on the port, such as lying face down or straps across the chest, and follow any guidance from the student’s care team.
Is it safe for someone who had lymph nodes removed to do yoga? Generally, yes. Current evidence supports gradual, progressive use of the affected arm or leg rather than protecting it from movement. A trained oncology yoga teacher knows how to build that safely.
