Post-Mastectomy & Breast Cancer Rehabilitation
Breast cancer surgery, particularly when lymph nodes are removed from the armpit, commonly leaves problems that have nothing to do with the cancer itself and everything to do with the shoulder, the arm and the tissue that was operated on. At Modern Physio we focus on understanding the root-cause of your problem & personalizing your treatment for lasting results.
Understanding Post-Mastectomy & Breast Cancer Rehabilitation
Breast cancer surgery, particularly when lymph nodes are removed from the armpit, commonly leaves problems that have nothing to do with the cancer itself and everything to do with the shoulder, the arm and the tissue that was operated on. Shoulder stiffness and reduced reach, tightness across the chest and armpit, altered sensation, scar restriction, and swelling of the arm are all common, and so is a specific and often alarming problem called axillary web syndrome, where tight visible cords appear running from the armpit down the inner arm and restrict movement. Lymphoedema of the arm is widely reported in around one in five women after axillary lymph node dissection, with the risk considerably lower after sentinel node biopsy alone. The most important thing we can tell you is that the old advice was wrong. For years women were told to avoid lifting or resistance training with the affected arm, for fear of triggering or worsening lymphoedema. The Physical Activity and Lymphedema trial, published in the New England Journal of Medicine, tested slowly progressive weightlifting in nearly three hundred breast cancer survivors, both those with existing lymphoedema and those at risk, and found it did not increase lymphoedema incidence or exacerbation. That finding overturned decades of protective advice. The qualification is that the programme was slow, supervised and progressive, so this supports graduated strength training rather than an unstructured return to heavy lifting. At Modern Physio in Vaishali Nagar, Jaipur, we work to your surgeon's timing and rebuild shoulder movement, strength and confidence.
Common Symptoms
- Restricted shoulder movement, particularly reaching overhead or behind the back
- Tightness across the chest, armpit or upper arm
- Visible or palpable tight cords running from the armpit down the inner arm, which is axillary web syndrome
- Pain or pulling when reaching, dressing or washing hair
- Swelling of the arm, hand or the area near the surgery
- Numbness or altered sensation on the inner upper arm and around the scar
- Scar tissue that feels tethered or restricts movement
- Weakness of the arm and shoulder from a period of reduced use
- Postural changes, including a protective rounded shoulder on the operated side
- Neck and upper back pain developing from altered posture and movement
- Fatigue, particularly during and after radiotherapy or chemotherapy
How Common Is It?
Lymphoedema of the arm is widely reported in approximately one in five women following mastectomy with axillary lymph node dissection, with risk increased by axillary radiotherapy and by the number of nodes removed, and markedly lower where only a sentinel node biopsy was performed. Shoulder movement restriction, chest and axillary tightness and altered sensation are common in the early months. Axillary web syndrome typically appears in the weeks after surgery and is a recognised, generally self-limiting complication that responds well to treatment. Breast cancer treatment volumes in urban India, including Jaipur with its tertiary oncology services, mean this is a substantial and under-served rehabilitation population rather than a rare referral.
Causes & Risk Factors
- Surgery to the breast and, in particular, removal of lymph nodes from the armpit
- Axillary lymph node dissection, which carries considerably higher lymphoedema risk than sentinel node biopsy alone
- Radiotherapy to the armpit and chest wall, which causes tissue scarring and stiffness over time
- Scar tissue formation restricting movement across the chest and armpit
- Axillary web syndrome, where cords of tissue develop in the armpit and along the inner arm after surgery
- A period of protective non-use of the arm, which leads quickly to stiffness and weakness
- Advice to avoid using or loading the arm, which is now understood to be counterproductive
- Nerve irritation or division during surgery, causing altered sensation
- The general deconditioning that accompanies cancer treatment
Our Diagnosis Process
- Coordination with your surgical and oncology team, including clearance on timing before shoulder range work begins
- Review of exactly what surgery was performed, particularly whether axillary dissection or sentinel node biopsy was done, since this determines lymphoedema risk
- Measurement of shoulder range in all directions, compared with the other side
- Baseline limb measurement at defined points, so that any developing swelling is detected early rather than late
- Examination for axillary web syndrome, meaning the tight cords running from the armpit into the arm
- Assessment of scar mobility and tissue tightness across the chest and armpit
- Assessment of arm and shoulder strength, and of posture
- Discussion of your treatment plan, since radiotherapy and chemotherapy affect timing, fatigue and what is realistic
Our Treatment Approach
- Early shoulder range of movement work, with timing agreed with your surgeon rather than applied from a fixed protocol
- Exercise and stretching for axillary web syndrome, which systematic review evidence identifies as the most effective physiotherapy approach for this problem
- Scar mobilisation once the wound has healed and your surgeon is satisfied
- Progressive strength training for the arm and shoulder, introduced slowly and supervised, which trial evidence shows does not increase lymphoedema risk
- Baseline and repeated limb measurement so that swelling is picked up early, when it is easiest to manage
- Compression garment assessment and fitting where lymphoedema develops or where risk is high
- Postural work to address the protective rounded shoulder pattern that develops on the operated side
- Graded general conditioning, adjusted around chemotherapy and radiotherapy cycles and the fatigue that accompanies them
- Skin care education for the at-risk arm, focused on infection prevention rather than fear of using the limb
- Reassurance and clear explanation, since a great deal of avoidable disability comes from women being afraid to use the arm
Key Highlights
Graduated strength training, supported by trial evidence showing it does not increase lymphoedema risk
Specific treatment for axillary web syndrome, where exercise and stretching have the best support
Early and repeated arm measurement so swelling is caught before it becomes established
Timing coordinated with your surgical and oncology team rather than a fixed protocol
Recovery & Prevention Tips
- Use your arm. The old advice to protect it and avoid lifting has been overturned by trial evidence, and non-use causes stiffness, weakness and loss of function
- Follow your surgeon's guidance on when to begin shoulder movement, since the timing after surgery is a surgical decision
- Build strength gradually and under supervision, which is what the evidence supports, rather than jumping straight to heavy loads
- Report new cords in the armpit or arm rather than waiting, since axillary web syndrome responds well to exercise and stretching
- Have your arm measured at baseline and periodically, because swelling caught early is far easier to manage
- Look after the skin on the at-risk arm and treat cuts and infections promptly, while still using the arm normally
- Report any new swelling, or a feeling of heaviness or tightness in the arm, promptly
- Pace yourself through chemotherapy and radiotherapy, and expect fatigue to affect what you can do
- Keep an eye on your posture, since protecting the operated side quietly becomes a rounded shoulder and neck pain
- Seek same-day medical care if the arm becomes red, hot and painful with feeling unwell, which suggests infection

Evidence & Sources
The Physical Activity and Lymphedema trial, a randomised controlled trial of slowly progressive weightlifting in breast cancer survivors both with and at risk of lymphoedema, found that weightlifting did not increase the incidence or exacerbation of lymphoedema, overturning previous advice to avoid resistance training with the affected arm.
Schmitz et al. - Weight lifting in women with breast-cancer-related lymphedema (New England Journal of Medicine, 2009)A systematic review and meta-analysis of physiotherapy for axillary web syndrome after breast cancer found that exercise and stretching are the most effective physiotherapy interventions, with manual therapy, scar massage and myofascial release producing poorer results, while noting that the pooled pain outcome drew on only three small studies.
Effectiveness of physical therapy in axillary web syndrome after breast cancer: systematic review and meta-analysis (PMC, 2023)Frequently Asked Questions
I was told never to lift anything heavy with that arm. Is that right?
That advice is out of date, and it caused a great deal of unnecessary disability. The Physical Activity and Lymphedema trial tested slowly progressive weightlifting in nearly three hundred breast cancer survivors, including women who already had lymphoedema and women at risk of it, and found it did not increase lymphoedema incidence or exacerbation. The important qualification is that the programme was slow, supervised and progressive, so this supports graduated strength training rather than suddenly lifting heavy weights. What is clear is that protecting the arm by not using it costs you strength and function without protecting you from swelling.
What are these tight cords in my armpit and arm?
That is almost certainly axillary web syndrome, sometimes called cording. Tight, often visible cords develop running from the armpit down the inner arm, occasionally as far as the wrist, usually appearing in the weeks after surgery. They can be alarming and they restrict reaching considerably. The reassuring part is that it responds well to treatment: systematic review evidence identifies exercise and stretching as the most effective physiotherapy approach, performing better than manual therapy and massage-based techniques. It generally resolves over weeks with appropriate treatment rather than being permanent.
What is my actual risk of lymphoedema?
It depends substantially on what surgery you had. Lymphoedema is widely reported in around one in five women after axillary lymph node dissection, with risk increased further by radiotherapy to the armpit and by the number of nodes removed. Risk after sentinel node biopsy alone, where only one or a few nodes are taken, is considerably lower. That is why we ask exactly what was done rather than treating everyone the same. Knowing your risk matters because it determines how closely we measure your arm and how much emphasis we put on early detection.
When can I start moving my shoulder after surgery?
That is a decision for your surgeon rather than a fixed rule, and we work to their guidance. There is genuine debate in the literature about optimal timing, balancing earlier movement for better shoulder recovery against a slightly higher risk of wound complications and seroma if started very early. What is well supported is that shoulder movement work does need to happen, because prolonged immobility after this surgery produces stiffness that is much harder to reverse later. We coordinate with your surgical team rather than applying one protocol to everyone.
Why does my arm feel numb near the scar and inner arm?
Nerves supplying sensation to the inner upper arm and the area around the armpit run through the surgical field, and they are frequently stretched, irritated or divided during axillary surgery. The result is numbness, altered sensation or occasionally an oversensitive area, typically on the inner upper arm. It is common, expected, and usually improves over months, though some altered sensation can persist. It does not affect the strength of your arm. The practical implication is skin care: with reduced sensation you may not notice a burn or a cut, so check the area.
Should I have my arm measured even if it looks normal?
Yes, and this is one of the more valuable things we do. Baseline measurement before or soon after surgery, followed by periodic remeasurement, allows a developing swelling to be detected while it is still subtle and highly treatable. By the time an arm looks obviously swollen, the condition is more established and harder to reverse. Measurement is quick and non-invasive. It also has a reassuring function: many women worry about every sensation in the arm, and objective measurement often confirms that nothing is happening.
Can I exercise during chemotherapy or radiotherapy?
Generally yes, with adjustments, and it is usually beneficial rather than harmful. Fatigue is the main limiting factor, and it often follows a predictable pattern through treatment cycles, so we plan around it: more on better days, less around the days you know are hardest. Exercise during treatment helps maintain strength and function and often helps fatigue itself. What needs coordinating with your oncology team is timing around blood counts, any specific restrictions they have given you, and skin care during radiotherapy. We work within whatever they advise.
Is it too late if my surgery was years ago?
No. Shoulder stiffness, chest and axillary tightness, weakness and postural change all respond to treatment years after surgery, and many women are never offered any rehabilitation at all, so late referral is common rather than unusual. Established lymphoedema is managed rather than cured, but it can still be brought under much better control at any stage with proper compression, skin care and exercise. Late-developing shoulder problems and lymphoedema are both recognised, so a new problem years later does not mean something has gone wrong with the cancer treatment.
