Shoulder Stiffness After Breast Cancer Surgery? Causes And Best Exercises

Shoulder stiffness is a common concern during recovery from breast cancer surgery.

After a mastectomy, lumpectomy or lymph-node procedure, you may notice that lifting your arm feels difficult, reaching overhead is uncomfortable, or movements that were previously effortless now feel restricted.

This can happen for several reasons.

Pain may cause you to protect the arm, while changes around the chest, armpit and shoulder can affect normal movement.

Reduced activity during the early recovery period can also contribute to stiffness and weakness.

The good news is that shoulder stiffness does not necessarily have to become a permanent limitation.

Appropriate movement, progressive exercise and physiotherapy can help restore shoulder function while respecting the healing process.

Why Does Shoulder Stiffness Happen After Breast Cancer Surgery?

Shoulder stiffness after breast cancer surgery can have more than one cause.

Understanding what is contributing to the restriction is important because treatment should be based on the underlying problem rather than simply trying to stretch the shoulder harder.

Pain and Protective Movement

Pain is one of the body’s natural protective responses after surgery.

When moving your arm hurts, you may instinctively keep it closer to your body and avoid reaching overhead.

Although this may be appropriate during the initial healing period, prolonged avoidance can contribute to reduced shoulder movement.

This can create a cycle:

Pain → less movement → stiffness → difficulty moving → reduced confidence → even less movement.

Physiotherapy aims to gradually interrupt this cycle while keeping exercise appropriate for your stage of recovery.

Chest and Shoulder Muscle Tightness

Breast cancer surgery can affect tissues around the breast, chest wall and armpit.

You may experience a pulling or tight sensation when raising the arm.

This can make normal shoulder movement feel restricted even when the shoulder joint itself is not the primary problem.

The chest and shoulder muscles may also become tense when you spend more time protecting the surgical area.

Lymph-Node Surgery

Procedures involving the lymph nodes can affect how the shoulder and arm move.

Some people develop axillary web syndrome, commonly referred to as cording, after axillary lymph-node surgery.

It may present as tight cords or bands under the skin around the armpit and arm, sometimes accompanied by restricted shoulder movement.

A systematic review has identified axillary web syndrome as a recognized complication after breast cancer surgery and highlighted its association with reduced upper-limb function (Yeung et al., 2015).

A physiotherapist can assess whether cording may be contributing to your restricted movement and determine an appropriate rehabilitation approach.

Does Breast Cancer Surgery Affect Shoulder Range of Motion?

It can.

Research has demonstrated that shoulder range of motion can be reduced following breast cancer surgery, particularly during the early stages of recovery.

The extent of restriction varies considerably between individuals.

Factors such as the type of surgery, lymph-node treatment, pain, reconstruction and subsequent radiotherapy can all influence recovery.

A systematic review examining exercise interventions for upper-limb dysfunction found that exercise can improve shoulder range of motion and function following breast cancer treatment (McNeely et al., 2010).

This is one reason rehabilitation focuses on gradually restoring useful movement rather than simply waiting for stiffness to disappear on its own.

What Does Shoulder Stiffness Feel Like?

Shoulder stiffness can feel different from person to person.

You may notice:

• Difficulty raising your arm above your head
• Tightness across the chest
• A pulling sensation near the armpit
• Difficulty reaching behind your back
• Difficulty putting on or removing clothing
• Trouble brushing or styling your hair
• Discomfort when sleeping on the affected side
• Reduced ability to reach shelves or cupboards
• Weakness when using the affected arm

Some people describe the shoulder as feeling “stuck,” while others mainly notice tightness or discomfort at the end of a movement.

These symptoms do not necessarily mean that the shoulder joint has been damaged.

Can Scar Tissue Cause Shoulder Stiffness?

Scar tissue may contribute to a feeling of tightness around the surgical area.

As the incision heals, scar tissue forms as part of the normal healing process. In some individuals, changes in the mobility of the scar and surrounding tissues can affect how comfortably the chest and shoulder move.

However, scar-related tightness is only one possible contributor.

A physiotherapist can assess the scar, chest wall, shoulder and surrounding tissues to determine whether restricted tissue mobility may be affecting your movement.

When Is Scar Management Appropriate?

Scar management should only begin once the surgical wound has adequately healed and your healthcare team considers it safe.

Depending on your recovery, a physiotherapist may use appropriate scar-mobility techniques alongside exercises.

You should not massage an open, infected or incompletely healed wound.

Can Radiotherapy Make the Shoulder Feel Stiff?

Radiotherapy can affect tissues in the treated area, and some people experience changes in skin and soft-tissue flexibility during or after treatment.

This may contribute to tightness around the chest wall and shoulder.

The timing and severity of these changes vary.

If you are receiving radiotherapy, your rehabilitation programme may need to be modified according to your treatment schedule and symptoms.

Rather than forcing a stiff shoulder through aggressive stretching, physiotherapy can use gradual mobility and strengthening strategies suited to your circumstances.

What Happens During a Physiotherapy Assessment?

A physiotherapist will typically begin by understanding your surgery, treatment history and current symptoms.

They may ask about:

• Type of breast surgery
• Lymph-node procedures
• Reconstruction
• Radiotherapy or other treatments
• Pain levels
• Arm or hand swelling
• Shoulder movement
• Daily activities that are difficult
• Your rehabilitation goals

They may then assess shoulder range of motion, strength and functional movement.

The assessment may also include looking at your posture, shoulder-blade movement, chest-wall mobility and the tissues around the surgical area.

Why Is an Individual Assessment Important?

Two women can undergo similar breast cancer surgeries but have completely different recovery experiences.

One person may primarily have shoulder stiffness, another may have weakness, while another may have cording or lymphoedema-related symptoms.

Therefore, treatment should not be based on a generic list of exercises alone.

The physiotherapist’s role is to identify the factors contributing to your limitation and develop a programme that can progress as your recovery improves.

Can Shoulder Stiffness Be Treated With Exercise?

In many cases, exercise is an important part of rehabilitation.

The programme may begin with gentle range-of-motion exercises and gradually progress toward active movement, strengthening and functional activities.

Exercise interventions have been shown to improve physical function and quality of life in people recovering from cancer treatment (Campbell et al., 2019).

However, exercises should be appropriate for your surgical stage.

More exercise is not automatically better.

The objective is to restore movement and physical capacity progressively without unnecessarily irritating healing tissues.

What Is the Goal of Physiotherapy?

The goal is not simply to make your shoulder flexible.

Effective rehabilitation aims to help you:

• Move your arm comfortably
• Regain useful shoulder range
• Improve strength
• Reduce movement-related fear
• Return to daily activities
• Improve confidence using the affected arm
• Recognise symptoms that require further assessment

Ultimately, successful rehabilitation means being able to use your arm for the activities that matter to you.

What Exercises Can Help Improve Shoulder Movement?

Once your surgical team confirms that movement is appropriate, a physiotherapist may gradually introduce exercises designed to restore shoulder mobility.

The program usually starts with comfortable, controlled movements and progresses as your recovery allows.

Research supports combining range-of-motion exercises with strengthening to improve shoulder movement after breast cancer surgery (Ribeiro et al., 2019).

The exercises may include the following.

Shoulder Flexion

Shoulder flexion involves gradually raising your arm forward and upward.

Initially, you may perform this movement with assistance from your other arm or a physiotherapy tool such as a stick.

As your mobility improves, you can gradually perform the movement independently.

The goal is not to force the arm overhead. Instead, work toward progressively increasing comfortable movement.

Shoulder Abduction

This involves gradually moving the arm out to the side.

Abduction can sometimes feel particularly restricted following breast cancer surgery, especially when there is tightness around the chest or armpit.

A physiotherapist can determine an appropriate range and help you progress it safely.

Wall-Walking Exercises

You may be asked to face a wall and slowly “walk” your fingers upward.

This provides a simple way to gradually increase shoulder elevation while allowing you to control the range of movement.

The movement should remain comfortable and controlled rather than becoming an aggressive stretch.

Shoulder Rotation

Gentle internal and external rotation exercises can help restore the rotational movements required for dressing, grooming and reaching behind your body.

These may initially be performed with the elbow supported or kept close to your side.

Should You Stretch a Stiff Shoulder?

Gentle stretching can be useful when restricted soft-tissue mobility is contributing to stiffness.

However, stretching should not be forced.

A strong pulling sensation does not necessarily mean that the exercise is working better.

Excessive force can make an already sensitive area more uncomfortable.

Your physiotherapist may combine gentle stretching with active movement, breathing and strengthening rather than relying on stretching alone.

What If You Have Axillary Web Syndrome or Cording?

Axillary web syndrome can produce tight, cord-like structures extending from the armpit toward the arm.

It may become particularly noticeable when the arm is raised.

Physiotherapy management can include stretching, active movement, manual techniques and progressive exercises.

A systematic review found that rehabilitation approaches for axillary web syndrome may improve pain, upper-limb function and clinical resolution, although the authors noted that further high-quality research is needed (Lippi et al., 2022).

Another systematic review and meta-analysis reported that exercise and stretching were among the more effective physiotherapy approaches for improving range of motion in people with axillary web syndrome, although the evidence base remains limited (González-Rubino et al., 2023).

Can Cording Be Treated With Massage?

Manual therapy, scar mobilisation and other hands-on techniques may be incorporated by appropriately trained clinicians.

However, treatment should be individualised. Not every tight sensation following breast cancer surgery represents cording, and not every person needs the same manual treatment.

The physiotherapist should first establish what is restricting movement before selecting an intervention.

When Should Strengthening Begin?

Once adequate healing has occurred and your medical team considers resistance exercise appropriate, strengthening can gradually become part of rehabilitation.

The purpose is to restore the capacity of the shoulder and upper limb rather than simply increase muscle size.

You may eventually perform exercises such as:

• Resistance-band rows
• Shoulder external rotation
• Shoulder flexion with light resistance
• Shoulder abduction with light resistance
• Wall push-ups
• Progressive upper-body strengthening

The resistance should initially be appropriate for your current capacity.

Why Is Progressive Strengthening Important?

Stiffness and weakness can reinforce each other.

If your shoulder feels weak, you may avoid using it.

If you continue avoiding it, everyday activities can remain difficult and your physical capacity may not fully recover.

Progressive strengthening helps your body adapt to increasing physical demands.

A 2025 systematic review and meta-analysis of 22 randomized controlled trials found that exercise interventions after breast cancer surgery improved muscle strength, shoulder range of motion and upper-limb function, while also reporting benefits for postoperative pain and quality of life (Xue et al., 2025).

Is Strength Training Safe If Lymph Nodes Were Removed?

Lymph-node removal does not automatically mean that you must avoid strengthening exercises.

Instead, exercise should generally be introduced progressively and monitored according to your individual circumstances.

If you have concerns about lymphoedema, your physiotherapist can assess your symptoms and help determine an appropriate progression.

A study of resistance exercise in women at risk of breast cancer-related lymphoedema found that progressive resistance training did not increase lymphoedema incidence compared with usual care (Schmitz et al., 2010).

This is an important distinction: having lymph nodes removed does not mean the arm should never be strengthened.

What About Scar and Chest-Wall Tightness?

Shoulder movement can sometimes be limited by tightness around the surgical area rather than by the shoulder joint alone.

A physiotherapist may therefore assess:

• Scar mobility
• Chest-wall movement
• Pectoral muscle flexibility
• Shoulder-blade movement
• Rib-cage mobility
• Shoulder-joint movement

Once the wound has fully healed and scar treatment has been cleared by your healthcare team, appropriate scar-mobility techniques may be introduced.

Why Treat the Chest Wall?

The shoulder does not work in isolation.

The shoulder blade, collarbone, ribs, chest wall and upper spine all contribute to normal upper-limb movement.

If movement around the chest wall is restricted, the shoulder may compensate.

This is why rehabilitation should look at the whole movement system, rather than treating the shoulder joint alone.

Can Physiotherapy Help With Shoulder Blade Movement?

Yes.

After surgery, some people change how they hold or move the shoulder because of discomfort or fear.

This can affect the normal movement of the shoulder blade during arm elevation.

Physiotherapy may include exercises that improve awareness and control of the shoulder blade, such as gentle scapular retraction, controlled arm elevation and rowing movements.

The objective is to restore coordinated movement rather than force the shoulder into a particular posture.

How Should Exercise Progress?

A useful rehabilitation principle is:

Mobility first → controlled movement → strength → functional activity.

However, these stages can overlap.

You do not necessarily need to achieve completely normal shoulder movement before beginning all strengthening exercises.

Your physiotherapist can combine appropriate mobility and strengthening work according to your recovery.

Monitor Your Response

Pay attention to how your shoulder responds during and after exercise.

Mild muscular effort or temporary stretching sensations may occur, but significant or progressively worsening pain is a reason to modify the exercise and seek professional guidance.

New swelling, marked heaviness or other unusual symptoms should also be discussed with your healthcare team.

Can You Exercise During Cancer Treatment?

In many cases, physical activity can remain part of cancer care, but the programme may need to be adapted around surgery, chemotherapy, radiotherapy, fatigue and other treatment-related factors.

Exercise intensity may need to change from one stage of treatment to another.

Your physiotherapist and oncology team can help determine what is appropriate based on your current health and treatment plan.

What Is the Main Goal of Treatment?

The goal is not simply to achieve a perfect shoulder range of motion.

A successful rehabilitation program should help you use your arm comfortably and confidently in real life.

That may mean being able to:

• Put on a shirt without difficulty
• Reach overhead
• Brush your hair
• Sleep more comfortably
• Carry everyday objects
• Perform household tasks
• Return to work
• Resume exercise or recreational activities

Shoulder mobility matters because it supports these everyday functions.

Can Shoulder Stiffness Be Prevented After Breast Cancer Surgery?

Shoulder stiffness cannot always be prevented, particularly when surgery, lymph-node treatment or radiotherapy affects the surrounding tissues.

However, appropriate rehabilitation can help reduce functional limitations and support recovery.

One of the most important principles is to avoid unnecessary prolonged inactivity once movement has been cleared by your healthcare team.

A structured rehabilitation programme that includes mobility and progressive exercise can help maintain shoulder function and support a return to daily activities.

The key is appropriate movement at the appropriate stage, rather than trying to do as much exercise as possible immediately after surgery.

How Long Does Shoulder Stiffness Last?

There is no single recovery timeline.

Some women notice substantial improvement within weeks, while others experience stiffness for several months, particularly when they have undergone more extensive surgery or additional cancer treatment.

Recovery can also fluctuate.

You may improve initially and then experience increased tightness during another phase of treatment.

What matters is whether your movement and function are gradually improving.

If your shoulder remains significantly restricted, becomes increasingly painful or interferes with everyday activities, a physiotherapy assessment can help identify the contributing factors.

What If My Shoulder Is Still Stiff Months After Surgery?

Persistent stiffness should not automatically be accepted as something you simply have to live with.

A physiotherapist can reassess your shoulder and determine whether the limitation may be related to:

• Reduced joint mobility
• Muscle weakness
• Chest-wall tightness
• Scar restrictions
• Axillary web syndrome
• Pain-related guarding
• Changes following radiotherapy
• Reduced physical activity

The treatment plan can then be modified according to your current stage of recovery.

Research suggests that exercise-based rehabilitation can continue to provide benefits for shoulder function following breast cancer treatment, including improvements in range of motion and physical function (McNeely et al., 2010).

When Should You Stop an Exercise?

You should not push through significant or worsening pain simply because an exercise is part of your rehabilitation programme.

Stop the exercise and seek appropriate guidance if you experience symptoms such as:

• Sudden or severe pain
• New or increasing swelling
• Significant redness or warmth
• Wound problems
• New weakness
• New or worsening numbness
• Symptoms that persist or progressively worsen after exercise

Your rehabilitation programme should be adjusted when your symptoms indicate that the current level of activity is not appropriate.

How Can You Make Rehabilitation More Effective?

Consistency is often more useful than intensity.

Instead of attempting difficult exercises occasionally, focus on performing the exercises prescribed by your physiotherapist regularly and correctly.

Focus on Movement Quality

Do not rush through repetitions.

Controlled movement allows you to understand how your shoulder is responding and helps you identify restrictions that may need attention.

Progress Gradually

Once an exercise becomes comfortable and your physiotherapist considers you ready, resistance, repetitions or movement range can be increased.

This gradual progression helps your body adapt without unnecessarily overwhelming recovering tissues.

Connect Exercises With Daily Activities

Your rehabilitation should eventually reflect what you actually need to do.

If reaching overhead is difficult, rehabilitation can incorporate overhead movement.

If carrying groceries is challenging, progressive strengthening can eventually address that physical demand.

This makes physiotherapy more meaningful and functional.

Lesser-Known Facts About Shoulder Stiffness After Breast Cancer Surgery

Stiffness Does Not Always Come From the Shoulder Joint

A person may feel that the “shoulder” is stiff even when restrictions are partly coming from the chest wall, scar tissue, armpit or shoulder-blade movement.

That is why a comprehensive assessment is more useful than treating the shoulder joint in isolation.

Cording Can Appear After Surgery

Axillary web syndrome can develop following lymph-node surgery and may cause a pulling sensation extending from the armpit into the arm.

Recognising it early can help ensure that appropriate rehabilitation is considered rather than assuming that all postoperative stiffness is simply normal recovery.

Strengthening Is Part of Recovery Too

Rehabilitation does not end when your shoulder range improves.

Once appropriate, progressive strengthening can help restore the capacity required for everyday activities and reduce the tendency to avoid using the affected arm.

Recovery Can Continue Beyond the Initial Healing Period

The surgical wound may heal before your shoulder has completely recovered its movement and strength.

This is why rehabilitation may continue beyond the early postoperative period, particularly when additional treatments affect mobility or physical capacity.

Final Thoughts

Shoulder stiffness after breast cancer surgery can be frustrating, particularly when everyday movements suddenly become difficult.

But restricted movement does not mean that you have to accept permanent loss of shoulder function.

Physiotherapy can help you understand why your shoulder is stiff and what can be done about it.

Treatment may include gentle mobility exercises, progressive strengthening, scar management, cording-related rehabilitation and guidance around returning to daily activities.

The most effective approach is individualised.

Your surgery, lymph-node treatment, radiotherapy, symptoms and overall recovery all influence how rehabilitation should progress.

Rather than forcing the shoulder or avoiding movement altogether, aim for gradual, consistent and appropriate rehabilitation.

If stiffness persists, becomes painful or begins interfering with your normal activities, speak with your healthcare team or a physiotherapist experienced in breast cancer rehabilitation.

Recovery is not about rushing your shoulder back to normal, it is about gradually helping it become strong, mobile and functional again.
