What my physical therapist taught me about my shoulders after cancer

I went in expecting foam rollers, stretchy bands, and a list of generic stretches. What my physiotherapist handed me instead was a mirror, a tissue box, and a long list of questions about how I actually use my body in a normal day. The appointment was at a quiet clinic in inner Melbourne, the kind with reclaimed timber benches and a kettle in the corner. We spent most of the first session just talking, which surprised me, because I had assumed I would spend the whole hour face-down on a treatment table.

For four years after my mastectomy, my shoulders had quietly become a casualty of cancer treatment. I had blamed the lingering stiffness on surgery, on scar tissue, on the cording that ran like a guitar string down my armpit. I had accepted the limited range of motion as the price of survival. I have written about the slow unravel of post-surgery stiffness over on the blog, and it remains one of the most-read topics in our corner of the survivorship world.

I had asked my surgeon. I had asked my GP. I had stretched in front of the telly at night and followed the YouTube videos everyone recommends. Nothing shifted the heavy, locked sensation between my shoulder blades. It took a women's health physiotherapist asking me, "when was the last time you raised your arm above your head without thinking about it," for me to realise how much I had quietly been compensating.

That was the moment the recovery I thought I had finished officially restarted.

The day I couldn't reach the top shelf

I remember exactly when I knew something was wrong. I was at my local Coles in Brisbane, reaching for a jar of vegemite on the top shelf, and my right arm simply refused to cooperate. It froze halfway, trembling in a way that was mortifying in a public place. A stranger reached it down for me, smiled kindly, and probably forgot about it within two minutes. I went home and cried at my kitchen table.

It was not the first time my shoulder had misbehaved. It was the first time I could not pretend it was just a stiff neck from sleeping funny. The reaching motion that used to be automatic required me to recruit muscles from my neck, my jaw, even my breath. I had built an entire compensation strategy without knowing it, and my body was paying the price for every awkward workaround I asked of it.

When I described this to my physio, she nodded like she had heard it a hundred times. She said the shoulder is a liar, that it will keep letting you down quietly until you give it what it needs.

Why shoulders suffer after breast cancer treatment

The mechanics of breast cancer treatment are brutal on the shoulder girdle, even when the surgery itself was on the breast and not the chest wall. Lymph nodes are removed or sampled, muscles are retracted and sometimes divided, scar tissue forms along planes that nature never intended to be glued together. After radiation, the soft tissue changes again, tightening like old leather.

My physio walked me through what was happening to my pectoral fascia, my latissimus dorsi, my serratus anterior. These are words I now know the way I once knew the names of the Wiggles songs my kids loved. The cording under my arm was collagen doing its best to heal, but doing so in the wrong direction. My rotator cuff was weak because it had stopped being the primary mover.

None of this is unusual. In Australia, one in seven women will be diagnosed with breast cancer before the age of 85, according to Cancer Council Australia, and shoulder dysfunction after treatment is one of the most common but least talked about after-effects. It is also one of the easiest things to leave unaddressed, especially when life is busy and the ache feels manageable.

My physio's first rule: stop shrugging

The first exercise she taught me was not an exercise at all. It was a prohibition. Stop shrugging your shoulders up toward your ears, she said. Stop hiking your shoulder blade up to meet your neck every time you reach, drive, type, or hold your phone. Stop living in your upper traps like they are paying rent.

I had not realised how much of my day was spent in subtle shoulder elevation. I checked my posture in windows, in the back of my phone screen, in the reflective surface of the kettle in my kitchen. The shrug was everywhere, and it was strangling the muscles underneath. My physio told me that upper traps are designed for short bursts of work, not the marathon of holding a phone, a steering wheel, or a toddler on one hip all afternoon.

She explained that chronic upper trap dominance is what happens when the deeper stabilisers of the scapula go offline after surgery. The bigger, fussier muscles take over by default, and they are not built for endurance. That is why my neck ached by 3pm every arvo even when I had done nothing physically demanding. Resources like this recovery guide lay out the same principle in plainer language, and they gave me vocabulary to keep using between sessions.

The strengthening work no one warned me about

What surprised me most was that the work was not gentle. My physio prescribed wall slides, prone Y-T-W raises, serratus punches, and banded rows with a tempo that left my mid-back trembling. None of it looked dramatic from the outside. From the inside, it was harder than any Pilates class I had ever attended.

The shoulder is not a single joint. It is a coordinated system of four joints and seventeen muscles, and cancer treatment had dismantled the unspoken choreography between them. Strengthening was less about getting bigger or fitter and more about rebuilding the relationship between muscles that used to work as a team.

Progress was slow and uneven. Some weeks I could lift my arm cleanly overhead by midweek. Other weeks, a single sleepless night would pull everything back into compensation. My physio kept reminding me that the goal was not perfection, it was reliable function. I have had to learn that lesson more than once, and I am still learning it.

Daily habits I now do without thinking

The biggest shifts came from the smallest things. I set a timer that reminds me to soften my shoulders down every ninety minutes while I work. I switched to a backpack instead of a one-shoulder tote, even when I am just popping down to the markets in Adelaide. I stand up to brush my teeth. I stopped pushing myself up from chairs with my hands.

The hardest habit was the simplest one. I had to learn to ask for help reaching things, not because I am broken, but because using the right muscles for the right task matters. It also meant having honest conversations at home about money, treatment top-ups, and what our budget actually allowed for extras. If you struggle with that kind of talk with a partner, this guide on financial conversations is a fair starting point.

These habits feel like nothing when I list them. They feel like everything when I forget one. They are also the things that travel with me on the days I do not have time to think about my shoulders at all.

Working with a physio through Medicare and private cover in Australia

Finding the right practitioner mattered more than any single exercise. My GP referred me under a Chronic Disease Management plan, which gave me a small Medicare rebate on a set number of sessions each year. On top of that, my private health cover with Bupa covered a portion of the remaining fee, so the out-of-pocket cost was manageable for our family budget.

Not every clinic bulk bills for these sessions, and not every physiotherapist has women's health training, so it is worth asking directly. The Australian Physiotherapy Association has a practitioner directory, and many cancer centres in Sydney, Perth, and Hobart now have in-house lymphoedema and shoulder rehab specialists. If you want to know more about how I approach the survivorship side of all this, you can find it on my about page.

Whatever you do, do not stop going because the gap feels too wide. A good physio will always have options, including telehealth, group rehab, and sliding scale fees for those going through active treatment.

What I carry with me into every appointment now

I turn up differently now. I arrive early. I bring a list of questions, even the awkward ones. I tell her when I have skipped exercises, when I have been awake half the night, when something hurts in a new way. None of that used to feel like part of my job, but it is the part that has changed my recovery the most.

I have learned that shoulder recovery is also a recovery of voice. Cancer taught me to be polite about my own needs. Physio is teaching me to be specific. Different therapist, different strategies, but the muscle underneath is the same one I am rebuilding in the gym.

The biggest lesson was the easiest one to miss. My shoulders were not failing me. They were carrying things I had never asked them to put down, and they were waiting for me to notice.

Shoulders do not respond to willpower. They respond to repetition, to load, to kindness, to time. The simplest commitment that has worked for me is to pick one small habit, repeat it daily for two weeks, and see what changes. A timer on the phone, a sticky note on the fridge, a habit paired with the first cup of coffee in the morning, any of these work. Small movements, done consistently, are what finally unstitched the stuckness I had assumed was permanent.
