Scar tissue after breast cancer surgery can sometimes cause tightness, sensitivity or restricted movement around the chest and shoulder, particularly when healing affects the surrounding skin and soft tissues.
A scar is a normal part of healing after breast cancer surgery.
Whether you have had a lumpectomy, mastectomy or lymph-node surgery, the incision gradually closes and the body produces collagen to repair the damaged tissue.
Over time, the scar may become flatter and softer, but it can sometimes remain firm, sensitive or tight.
Quick Answer
Scar tissue after breast cancer surgery is a normal part of healing, but it can sometimes contribute to tightness, tenderness, altered sensation or restricted shoulder and chest movement. Physiotherapy may help by combining appropriate scar mobilisation, mobility exercises, strengthening, stretching and functional rehabilitation. Scar treatment should only begin after the wound has adequately healed and your healthcare team has cleared you for hands-on treatment.
For some women, scar tissue is more than a cosmetic concern.
Changes around the surgical area can contribute to tightness, tenderness, altered skin sensation and restricted movement of the chest or shoulder.
The scar may also feel uncomfortable when clothing touches it or when the arm is raised.
This is where physiotherapy can become useful.
Physiotherapy does not simply focus on the appearance of a scar.
The broader goal is to help restore comfortable movement, reduce physical restrictions and support a return to everyday activities.
Research on postoperative breast cancer rehabilitation shows that physical therapy interventions can improve postoperative pain and shoulder range of motion,
although the evidence for specific techniques such as myofascial therapy remains less certain. (De Groef et al., 2015)

- A physiotherapist can assess the scar together with the shoulder, chest wall, arm and overall movement pattern.
What Is Scar Tissue After Breast Cancer Surgery?
Scar tissue is the body’s natural response to tissue injury.
When an incision is made during breast surgery, the body begins a healing process involving inflammation, new tissue formation and collagen remodelling.
The resulting scar is made from repaired tissue rather than the same organised tissue that was present before surgery.
Why Can a Surgical Scar Feel Tight?
As scar tissue matures, it can become firmer and less flexible than surrounding skin and connective tissue.
A scar may therefore feel:
- Tight when you stretch your arm
- Firm or thick compared with surrounding skin
- Sensitive or tender to touch
- Itchy during healing
- Numb or less sensitive
- Adherent to deeper tissues
- Uncomfortable when the shoulder or chest moves
Not everyone develops problematic scar tissue.
Some scars remain relatively soft and cause little or no functional limitation.
Can Scar Tissue Affect Shoulder Movement?
It can, particularly when the scar and surrounding tissues are located near the breast, chest wall or armpit.
After surgery, people may naturally protect the area by reducing arm movement because of pain or fear of disturbing the wound.
This can contribute to stiffness and reduced shoulder mobility.
A systematic review of early rehabilitation after breast cancer surgery found moderate evidence that range-of-motion exercises can improve shoulder flexion, abduction and external rotation, supporting the importance of rehabilitation alongside normal healing. (Ribeiro et al., 2019).
What Does Problematic Scar Tissue Feel Like?
Scar-related symptoms vary from person to person.
You might notice that the scar:
- Feels unusually hard or raised
- Pulls when you lift your arm
- Feels stuck to the underlying tissue
- Causes local tenderness
- Produces a stretching sensation across the chest
- Makes certain movements uncomfortable
- Feels sensitive when touched
- Is associated with reduced shoulder mobility
It is important to remember that these symptoms do not automatically mean the scar itself is the only cause.
Pain and restricted movement after breast cancer surgery can have several contributing factors, including muscle weakness, protective movement patterns, nerve-related sensory changes, lymphoedema and axillary web syndrome.
A physiotherapy assessment can help determine what is actually limiting movement rather than assuming every postoperative restriction is caused by scar tissue.
How Can Physiotherapy Help With Scar Tissue?
Physiotherapy can help when scar-related changes are contributing to pain, tightness, reduced mobility or difficulty using the arm comfortably.
Treatment is not limited to working directly on the scar.
A physiotherapist may assess the scar, skin, chest wall, shoulder, surrounding muscles and overall movement pattern to identify what is restricting function.
Scar Mobilisation
Once the surgical wound has fully healed and your healthcare team has cleared you for hands-on scar treatment, a physiotherapist may use gentle scar mobilization techniques.
These techniques can involve moving the skin and superficial tissues around the scar in different directions to encourage comfortable movement between the scar and surrounding tissues.
The aim is not to force or break the scar. Instead, treatment should be gradual and comfortable.
When Should You Start Scar Massage?
Scar massage should not be performed over an open, infected or incompletely healed incision.
Your surgical team or physiotherapist can advise when the wound is sufficiently healed for massage or other hands-on techniques.
This is particularly important after breast cancer surgery because healing times vary depending on the type of surgery, reconstruction, wound healing and any complications.
Does Scar Massage Actually Work?
Scar massage is commonly used in rehabilitation, but evidence for its effectiveness varies depending on the type of scar and the specific technique used.
A systematic review of physical scar-management interventions found that massage and other physical approaches may improve some scar characteristics and symptoms, although studies differ considerably in their methods and quality. (Shin & Bordeaux et al., 2012)
For breast cancer rehabilitation, therefore, scar mobilization should be viewed as one possible component of a broader rehabilitation program, rather than a guaranteed way to eliminate scar tissue.
What Exercises Can Help After Breast Surgery?
Exercise is an important part of recovery because the effects of surgery can extend beyond the scar itself.
A physiotherapist may prescribe exercises according to your stage of recovery, symptoms and surgical restrictions.
Gentle Shoulder Movement
Early rehabilitation may include comfortable movements such as:
- Shoulder flexion
- Shoulder abduction
- Shoulder circles
- Elbow and wrist movements
- Gentle chest-opening movements
These exercises can help restore mobility without placing unnecessary stress on healing tissues.
Progressive Strengthening
As healing progresses, strengthening exercises can be introduced.
These may eventually include:
- Resistance-band exercises
- Light weights
- Scapular strengthening
- Postural exercises
- Functional upper-body movements
The progression should be individualised rather than based solely on a fixed timeline.
Can Physiotherapy Reduce Tightness Around the Scar?
It can help when tightness is related to restricted soft-tissue mobility, shoulder stiffness, muscle guarding or reduced movement.
Treatment may combine:
- Scar mobilisation
- Soft-tissue techniques
- Stretching
- Shoulder mobility exercises
- Strengthening
- Postural rehabilitation
- Breathing and chest-expansion exercises
- Education about movement and recovery
The benefit often comes from addressing the whole movement system, rather than trying to manipulate the scar aggressively.
What About Numbness Around the Scar?
Numbness or altered sensation around a breast surgery scar is relatively common because small sensory nerves can be affected during surgery.
You may experience:
- Numbness
- Tingling
- Increased sensitivity
- Burning sensations
- Reduced sensation when touching the area
These changes do not necessarily mean that something has gone wrong with the scar.
Over time, sensation may change as nerves recover and the tissues remodel.
However, persistent, severe or worsening nerve-related symptoms should be discussed with your healthcare team.
Can Physiotherapy Help With Pain Around a Surgical Scar?
Yes, depending on the underlying cause.
Scar discomfort can sometimes occur because the tissues remain sensitive or because movement around the surgical area has changed.
Reduced shoulder movement can also contribute to muscle tension and discomfort.
Physiotherapy can address these factors through graded movement, exercise, education and appropriate hands-on treatment.
A broader rehabilitation approach is supported by evidence showing that physiotherapy after breast cancer surgery can improve pain, shoulder range of motion and upper-limb function. (De Groef et al., 2015)
When Should You Not Massage the Scar?
Avoid massaging the surgical area and seek medical advice if the wound is:
- Open
- Bleeding
- Increasingly red
- Hot or swollen
- Producing discharge
- Becoming increasingly painful
- Showing signs of infection
You should also follow your surgeon’s instructions if you have had reconstruction or another procedure requiring specific wound-care precautions.
Scar treatment should begin only when the tissues are ready.
Can You Treat Scar Tissue Yourself at Home?
Once you have been cleared for scar care, your physiotherapist can teach you appropriate techniques to continue at home.
A typical home programme may include gentle scar mobility, shoulder exercises and regular functional movement.
The important principle is consistency rather than force.
You should not aggressively pull, pinch or press the scar in an attempt to make it disappear.
If an exercise or scar technique causes significant pain, skin irritation or a persistent increase in symptoms, stop and discuss it with your healthcare professional.
How Long Does Scar Tissue Take to Mature After Breast Cancer Surgery?
Scar healing is a gradual process rather than something that finishes when the incision closes.
In the early stages, a scar may appear red, raised or relatively firm.
As healing continues, collagen is remodelled and the scar can gradually become flatter, softer and less noticeable.
The timeline varies considerably depending on the type of surgery, individual healing, infection or wound complications, reconstruction and other treatments.
Can Scar Tissue Disappear Completely?
Usually, a mature surgical scar does not disappear completely.
However, its color, texture, sensitivity and flexibility can change considerably over time.
The more important question from a physiotherapy perspective is often not how the scar looks, but whether it is affecting:
- Shoulder movement
- Chest-wall mobility
- Arm function
- Comfort
- Posture
- Daily activities
If the scar is not causing symptoms or restricting function, extensive treatment may not be necessary.
When Should You See a Physiotherapist?
Consider a physiotherapy assessment if you notice persistent:
- Tightness around the breast or chest
- Difficulty raising your arm
- Shoulder stiffness
- Pulling around the surgical area
- Pain with movement
- Sensitivity or discomfort around the scar
- Difficulty returning to normal activities
- Changes in movement because you are protecting the surgical area
Physiotherapy can be particularly useful when scar-related restrictions occur alongside shoulder weakness, lymphoedema or other postoperative complications.
Exercise-based rehabilitation has been shown to improve shoulder mobility and upper-limb function after breast cancer surgery, supporting its role in recovery. (Xu et al., 2024)
What Can You Expect During Physiotherapy?
Your first appointment may involve more than examining the scar.
A physiotherapist may assess:
- Scar mobility
- Shoulder range of motion
- Chest-wall movement
- Arm strength
- Posture
- Pain and sensitivity
- Swelling
- Functional movement
- Your current stage of cancer treatment and recovery
Based on the findings, your programme may include hands-on treatment, mobility exercises, strengthening, stretching, breathing exercises and a home programme.
The treatment should be progressive and adapted to your recovery, rather than using the same scar-treatment approach for everyone.
Is Scar Massage Enough?
Usually, no.
Scar massage may be useful for selected people once the wound has healed, but it should not replace rehabilitation when there are shoulder restrictions, weakness or functional problems.
A broader exercise programme may be more important for restoring movement and confidence.
Evidence from systematic reviews supports exercise-based rehabilitation for improving physical outcomes after breast cancer surgery, particularly shoulder mobility and upper-limb function. (Redemski et al., 2022)
What Can You Do at Home?
Once your surgical team has cleared you for normal activity and your physiotherapist has advised that scar care is appropriate, you can usually incorporate simple strategies into your recovery.
Keep Moving Within Your Restrictions
Gentle shoulder and arm movement can help prevent stiffness.
Avoid forcing your arm into painful positions, but do not unnecessarily keep it still for prolonged periods.
Follow Your Exercise Program
Perform prescribed mobility and strengthening exercises consistently.
As your tissues heal, exercises can usually be progressed gradually according to your symptoms and surgical restrictions.
Look After the Scar
Once completely healed, moisturising and appropriately taught scar-mobility techniques may help with comfort and tissue mobility.
Do not massage an open, infected or irritated wound.
Pay Attention to Your Whole Arm
If scar tightness occurs together with arm swelling, heaviness, unusual pain or reduced shoulder movement, mention all of these symptoms to your healthcare professional.
Treating only the scar may not address the full problem.
When Should You Contact Your Medical Team?
Scar changes should generally be assessed if they are accompanied by symptoms that are new, worsening or unusual for your recovery.
Contact your healthcare team if you notice:
- Increasing redness around the scar
- Heat or significant swelling
- New discharge
- Wound separation
- Increasing or severe pain
- Fever
- A new lump or significant change around the surgical area
- Rapidly changing breast or chest-wall appearance
These symptoms should not simply be attributed to normal scar formation.
Myth vs Fact
Myth: A scar should be massaged as soon as the stitches are removed.
Fact: The wound needs to be sufficiently healed before scar massage or mobilisation begins. Your surgical or rehabilitation team should advise when it is appropriate.
Myth: The harder you massage the scar, the faster it will soften.
Fact: Aggressive pressure is unnecessary and may irritate healing tissues. Scar treatment should be gentle and progressive.
Myth: Scar tissue is the only reason for shoulder stiffness after breast cancer surgery.
Fact: Pain, protective movement, muscle weakness, nerve changes, lymphoedema and other postoperative restrictions can also affect shoulder movement.
Myth: Physiotherapy is only needed when a scar looks abnormal.
Fact: Physiotherapy may be helpful when a scar is associated with tightness, pain, restricted movement or difficulty returning to normal activities, even when the scar looks relatively normal.
What Are the Lesser-Known Facts About Breast Surgery Scars?
A Scar Can Affect Movement Without Looking Dramatic
A relatively small or visually healed scar can still feel tight or sensitive and may influence how someone moves their shoulder.
The Scar Is Only One Part of the Healing Process
Changes can occur in the skin, fascia, muscles, nerves and connective tissues around the surgical area.
Rehabilitation therefore needs to consider the whole region.
Numbness Does Not Necessarily Mean Poor Healing
Sensory changes can occur because nerves are affected during surgery.
Altered sensation may persist even when the incision itself looks completely healed.
You Do Not Need to “Break Up” the Scar
Aggressive pressure is not necessary.
Scar mobilisation should be gentle, controlled and appropriate for the stage of healing.
Rehabilitation Is About Function, Not Just Appearance
A scar does not necessarily need treatment simply because it is visible.
Physiotherapy becomes particularly valuable when scar-related changes interfere with movement, comfort or everyday function.
Final Thoughts
Scar tissue is a normal part of healing after breast cancer surgery, but persistent tightness, pain or restricted movement does not have to be accepted as something you simply have to live with.
Physiotherapy can address scar mobility alongside shoulder movement, strength, chest-wall mobility and everyday function. Always allow the wound to heal adequately before beginning scar massage or mobilisation, and seek medical advice for new or worsening symptoms.
Final Thoughts
Scar tissue after breast cancer surgery is a normal part of healing, but it does not have to be ignored when it affects how you move or feel.
Physiotherapy can look beyond the scar itself and address the shoulder, chest wall, arm, strength, mobility and overall function.
Scar mobilization may be useful for some people, but it works best as part of an individualized rehabilitation program rather than as a standalone solution.
Most importantly, scar treatment should begin only when the wound has healed sufficiently and should never involve aggressive pressure.
If you are experiencing persistent tightness, pain, restricted shoulder movement or difficulty returning to normal activities after breast cancer surgery, speak with your healthcare team or a physiotherapist experienced in breast cancer rehabilitation./ht
Frequently Asked Questions
Can physiotherapy break down scar tissue?
Physiotherapy cannot literally remove or break apart scar tissue. Treatment aims to improve tissue mobility, movement, strength and function while helping manage symptoms.
How long should I wait before massaging my breast surgery scar?
There is no single timeline for everyone. Scar massage should begin only after the wound has adequately healed and your surgical or rehabilitation team has advised that it is appropriate.
Can scar tissue cause breast or chest tightness?
Scar-related restrictions and changes in surrounding tissues can contribute to a pulling or tight sensation, although other causes should also be considered.
Can exercise make a surgical scar worse?
Appropriately progressed exercise is generally an important part of breast cancer rehabilitation. However, the type and timing of exercise should respect your surgical restrictions and individual recovery.
Should I see a physiotherapist for a painful breast surgery scar?
If pain is persistent, affects movement or interferes with daily activities, a physiotherapy assessment may be helpful. Your medical team should also evaluate new or worsening symptoms.
