Populations and Risk Factors
- Women diagnosed with breast cancer (most common cancer in women; second leading cause of cancer death in women)
- Risk of lymphedema: 1–3% with sentinel node biopsy alone; 5–25% with full axillary lymph node dissection; risk increases further when axillary radiation is added to surgery
- Clients receiving radiation therapy face chronic vessel fibrosis — radiation damage to lymphatics is progressive and cumulative
- Age: breast cancer incidence increases with age; peak incidence 55–69 years
- Those with reconstructive implants may develop capsular contracture (fibrotic encapsulation of the implant)
- Bilateral mastectomy patients face bilateral lymphedema risk and bilateral ROM restrictions
- Genetic factors: BRCA1/BRCA2 carriers may undergo prophylactic mastectomy
Causes and Pathophysiology
Surgical Types and Their Implications
- Lumpectomy (breast-conserving surgery): removal of tumor with a margin of normal tissue; breast preserved; often combined with radiation; lower lymphedema risk but radiation fibrosis affects the treatment field
- Simple/total mastectomy: removal of all breast tissue including the nipple-areolar complex; no lymph node removal; chest wall structures preserved; lower complication rate
- Modified radical mastectomy: removal of breast tissue and axillary lymph nodes (levels I and II) while preserving pectoralis muscles — the most common mastectomy type; creates moderate lymphedema risk
- Radical mastectomy (Halsted): removal of breast, pectoralis major and minor, and all three levels of axillary lymph nodes — reserved for locally advanced disease; highest complication rate; creates significant chest wall deficit and severe lymphedema risk
Axillary Lymph Node Dissection — Why It Matters
- The axillary lymph nodes (approximately 20–40 nodes in 3 levels) are the primary drainage pathway for the ipsilateral upper extremity, breast, and lateral chest wall.
- Removing nodes disrupts lymphatic transport capacity — the remaining lymphatic vessels must compensate, and if lymphatic load exceeds residual transport capacity at any point in the patient's life, lymphedema develops.
- Sentinel node biopsy identifies the first node(s) receiving drainage from the tumor — if the sentinel node is cancer-free, full dissection is avoided, preserving most lymphatic architecture.
- The risk of lymphedema is cumulative: surgery + radiation + infection + obesity + aging each add incremental risk.
Axillary Web Syndrome (Cording)
- Cording is thrombosis and fibrosis of lymphatic channels and small veins in the axilla following node biopsy or dissection.
- Visible and palpable cord-like structures develop in the axilla, extending from the surgical site down the medial arm, sometimes reaching the antecubital fossa or even the wrist.
- Cording becomes most prominent during shoulder abduction — the cords tighten like guitar strings, mechanically limiting ROM.
- The cords are typically most symptomatic 2–8 weeks post-surgery and may resolve spontaneously over months, but manual treatment can accelerate resolution.
Nerve Damage
- Long thoracic nerve: courses along the lateral chest wall and is vulnerable during axillary dissection; damage causes serratus anterior paralysis, producing scapular winging and impaired shoulder flexion above 90 degrees
- Thoracodorsal nerve: innervates latissimus dorsi; damage causes weakness in shoulder extension, adduction, and internal rotation
- Intercostobrachial nerve: sensory nerve supplying the medial arm and axilla; most commonly damaged nerve in axillary surgery; produces numbness, tingling, or burning pain in the inner arm — may be permanent
Chest Wall and Shoulder Changes
- Surgical removal of breast tissue creates scar adhesions between the skin flap and underlying pectoralis fascia and chest wall.
- The pectoralis major (preserved in modified radical, removed in radical) and pectoralis minor develop adaptive shortening from post-surgical guarding and protracted shoulder posture.
- Compensatory thoracic kyphosis and ipsilateral shoulder protraction develop as the patient guards the surgical site.
- Adhesive capsulitis of the ipsilateral shoulder may develop from immobility and guarding — the combination of chest wall scarring and capsular restriction can severely limit functional ROM.
Signs and Symptoms
- Transverse or diagonal incision across the chest wall, possibly extending into the axilla
- Persistent heaviness, fullness, or deep ache in the ipsilateral arm (early lymphedema indicator)
- Visible or palpable cords in the axilla (AWS) that become more prominent during shoulder abduction — restrict ROM like taut guitar strings
- Numbness in the underarm and medial upper arm (intercostobrachial nerve damage — may be permanent)
- Rounded shoulders, increased thoracic kyphosis, ipsilateral shoulder protraction (compensatory posture)
- Limited shoulder flexion and abduction (typically most restricted in abduction and external rotation)
- Scapular winging (long thoracic nerve damage)
- Difficulty with ADLs: hooking a bra, combing hair, reaching overhead, lifting objects
- Chest wall tightness and scar adherence — skin over the chest wall does not glide freely
Assessment Profile
Subjective Presentation
- Chief complaint: "I can't raise my arm properly since the surgery" or "my arm feels heavy and swollen" or "I have tight cords in my armpit that pull when I reach up"; may also report numbness in the inner arm, difficulty with overhead activities, or emotional distress about body image changes
- Pain quality: tightness and pulling sensation in the axilla (especially with abduction); deep aching in the ipsilateral arm (lymphedema); burning or tingling in medial arm (nerve damage); dull, constant chest wall ache from scar adhesions; shoulder pain from developing capsulitis
- Onset: symptoms develop days to weeks post-surgery; cording typically appears 2–8 weeks post-surgery; lymphedema may appear weeks, months, or years after surgery; shoulder ROM loss is progressive if not actively addressed
- Aggravating factors: reaching overhead, abduction of the shoulder (tightens cords), carrying heavy objects with the affected arm, prolonged arm dependency (worsens lymphedema), blood pressure cuffs or constrictive clothing on the affected arm
- Easing factors: arm elevation reduces early lymphedema symptoms; gentle sustained stretching relieves cord tension temporarily; compression garments if lymphedema present; support of the affected arm reduces shoulder strain
- Red flags: Sudden onset of arm swelling with redness, warmth, and fever — suspect cellulitis; medical referral; do not massage the affected limb. New or rapidly worsening lymphedema without identifiable trigger — refer for investigation of possible cancer recurrence obstructing lymphatics. New hard mass or lump at surgical site or in axilla — urgent oncologic referral.
Observation
- Local inspection: surgical scar location and maturity (red = immature, white = mature); chest wall asymmetry (flattened or concave on surgical side); arm circumference asymmetry (compare bilaterally — >2 cm difference suggests lymphedema); visible axillary cording with shoulder abduction; presence of compression garments; reconstructive implant asymmetry or capsular contracture
- Posture: ipsilateral shoulder protraction and elevation; thoracic kyphosis (increased); head forward posture; lateral trunk lean away from the affected side; scapular winging if long thoracic nerve is damaged
- Gait: typically normal unless significant lymphedema limits arm swing on the affected side; guarded arm positioning — arm held close to the body in adduction and internal rotation
Palpation
- Tone: pectoralis major and minor hypertonic (post-surgical guarding and adaptive shortening); upper trapezius and levator scapulae hypertonic on the affected side (compensatory elevation); latissimus dorsi may be hypertonic or weakened depending on nerve status; infraspinatus and posterior rotator cuff tension from shoulder imbalance
- Tenderness: chest wall scar adherence — tenderness along the scar line and where skin is tethered to underlying fascia; axillary tenderness (surgical site); palpable cords in the axilla (AWS) — firm, linear, tender structures that may extend down the medial arm; levator scapulae and infraspinatus trigger points; intercostobrachial nerve distribution tenderness or altered sensation (medial arm, axilla)
- Temperature: affected arm may be slightly warmer than contralateral (if early lymphedema or inflammation present); increased warmth with erythema suggests cellulitis (red flag); chest wall scar area typically normal temperature once healed
- Tissue quality: chest wall scar tissue tethered to pectoralis fascia and ribs — restricted multidirectional glide; lymphedematous arm tissue may be soft/pitting (early) or firm/brawny (late); axillary cords palpate as taut, rope-like structures that become more prominent with shoulder abduction; medial arm may have altered sensation (numbness or hypersensitivity from intercostobrachial nerve damage) — unreliable pressure feedback in this zone
Motion Assessment
- AROM: shoulder flexion and abduction restricted — typically most limited in abduction (cording pulls tightest in this plane) and external rotation; scapulohumeral rhythm may be disrupted (excessive scapular elevation compensating for restricted GH motion); scapular winging during shoulder flexion if serratus anterior is compromised; compare bilaterally; note whether cords visibly tighten during movement
- PROM / end-feel: firm/inelastic end-feel from scar tissue and cording rather than normal capsular end-feel; PROM may moderately exceed AROM (scar tissue stretches under sustained passive load); in developing adhesive capsulitis, a capsular pattern emerges (ER most limited, then abduction, then IR) — distinguish this from the non-capsular restriction of cording alone; cords may produce a sudden "twang" or release during PROM at end-range
- Resisted testing: weakness in serratus anterior (long thoracic nerve damage — scapular winging on wall push-up); weakness in latissimus dorsi (thoracodorsal nerve damage — impaired shoulder extension and adduction); rotator cuff may be functionally weak from disuse but neurologically intact; grip strength may be reduced on the affected side from disuse and lymphedema
Special Test Cluster
| Test | Positive Finding | Purpose |
|---|---|---|
| Stemmer Sign (CMTO) | Inability to pinch a skin fold on the dorsum of the second finger on the affected side | Confirm Stage II+ lymphedema; high specificity for lymphedema diagnosis |
| Circumferential Girth Measurement (CMTO) | >2 cm asymmetry between corresponding landmarks on affected vs. unaffected arm | Quantify lymphedema severity; serial measurements track progression/response |
| Shoulder ROM Screen (Active Abduction, Flexion, ER) (CMTO) | Loss of GH forward flexion, abduction, or external rotation compared to contralateral side | Identify post-surgical adhesive capsulitis, cording restriction, or combined limitation |
| Scapular Winging Assessment (Wall Push-Up) (CMTO) | Medial border of scapula prominently lifts from thorax during wall push-up | Confirm long thoracic nerve damage and serratus anterior paralysis |
| Axillary Cord Assessment (Abduction Under Observation) (supplementary) | Visible or palpable taut cord(s) in the axilla that restrict abduction ROM | Identify axillary web syndrome (cording) and determine treatment approach |
| Sensation Screen (Medial Arm) (supplementary) | Altered sensation (numbness, tingling, burning) in the medial arm and axillary region | Identify intercostobrachial nerve damage; map zones of unreliable pressure feedback |
Lymphedema vs. cording vs. capsulitis: These three complications frequently coexist and must be distinguished because their treatment approaches differ. Lymphedema requires MLD. Cording responds to sustained stretching and gentle manual release. Adhesive capsulitis requires capsular mobilization. A patient may have all three simultaneously.
Differential Assessment
| Condition | Key Distinguishing Feature |
|---|---|
| Adhesive Capsulitis | Capsular pattern (ER most restricted, then abduction, then IR); firm capsular end-feel in all restricted directions; may coexist with post-mastectomy restriction but has a distinct capsular pattern |
| Rotator Cuff Pathology | Painful arc during active abduction; specific pain on resisted testing (supraspinatus, infraspinatus); typically no cording; ROM restriction is from pain rather than mechanical restriction |
| Thoracic Outlet Syndrome | Vascular and/or neurological symptoms in the arm (numbness, tingling, pallor, coolness); positive Roos/Adson's test; symptoms related to arm position rather than scar restriction |
| Cellulitis | Acute warmth, erythema, tenderness, systemic fever in the affected arm; may develop on top of existing lymphedema; medical referral for antibiotics; contraindication to massage |
| Cancer Recurrence (Local/Regional) | New hard mass at surgical site or in axilla; rapidly worsening lymphedema without other explanation; urgent oncologic referral |
CMTO Exam Relevance
- Stemmer sign is the specific objective test for detecting lymphedema — know the technique and interpretation
- Axillary web syndrome (cording) becomes more prominent during shoulder abduction — the cords tighten like guitar strings
- Scapular winging indicates long thoracic nerve damage (serratus anterior paralysis)
- Lymphedema risk ranges from 1–3% (sentinel node biopsy) to 5–25% (full axillary dissection)
- Written informed consent is mandatory before any assessment or treatment of the breast area
- Know the difference between sentinel node biopsy and full axillary dissection and their relative lymphedema risks
- Intercostobrachial nerve damage produces numbness in the medial arm — this is the most commonly damaged nerve in axillary surgery
Massage Therapy Considerations
- Primary therapeutic target: chest wall scar adhesion release to restore fascial mobility; axillary cord management; shoulder ROM restoration; compensatory postural dysfunction; lymphedema prevention and management in the affected limb
- Sequencing logic: address posterior shoulder girdle compensations first (upper trapezius, levator scapulae, rhomboids) to reduce protraction guarding; then release anterior chest wall (pectoralis major and minor) and scar adhesions; then address axillary cording; then restore shoulder ROM — this sequence ensures surrounding tissue is prepared before directly challenging the restricted structures
- Safety / contraindications: lymphedema risk is lifelong — avoid deep pressure, heavy kneading, or vigorous circulatory massage on the affected arm and ipsilateral trunk quadrant; written informed consent is mandatory before any assessment or treatment of the breast area; do not apply pressure over ports, PICC lines, or central venous catheters; if platelets are low (thrombocytopenia from chemotherapy), reduce pressure to skin-displacement level; avoid massage over active radiation field
- Heat/cold guidance: warm moist heat to posterior shoulder girdle and chest wall before scar and ROM work to improve tissue pliability; avoid heat on the affected arm if lymphedema is present (increases lymphatic load); cold application post-treatment if reactive inflammation develops at the scar or axilla
- Medication awareness: post-mastectomy clients may be on targeted therapies (trastuzumab/Herceptin for HER2-positive cancer — monitor for fatigue and dyspnea from cardiotoxicity; tamoxifen/aromatase inhibitors — may cause joint pain and stiffness); checkpoint inhibitors (pembrolizumab/Keytruda) may cause skin reactions; radiation recall can be triggered months after treatment completion
- Psychosocial awareness: mastectomy has significant psychosocial impact — altered body image, grief, anxiety; allow clients to remain clothed or use positioning alternatives until trust is established; some clients may not want the affected side exposed or touched initially
Treatment Plan Foundation
Clinical Goals
- Restore chest wall fascial mobility and reduce scar adhesion to underlying structures
- Improve shoulder ROM (particularly abduction and external rotation)
- Manage or resolve axillary web syndrome (cording)
- Prevent lymphedema progression and address compensatory musculoskeletal pain
Position
- Semi-reclined supine (30–45 degrees) for anterior chest wall and axillary work — more comfortable than flat supine for most post-mastectomy clients
- Side-lying (unaffected side down) for posterior shoulder girdle and lateral chest wall access
- Avoid prone positioning if uncomfortable due to chest wall pressure or reconstruction — always ask
- Affected arm supported on a pillow in slight abduction during treatment to prevent dependent edema
Session Sequence
- Posterior shoulder girdle relaxation — effleurage and myofascial release to upper trapezius, levator scapulae, and rhomboids on the affected side; these compensatory muscles are doing overtime from shoulder protraction guarding
- Lateral and posterior chest wall — release latissimus dorsi, serratus anterior (if intact), and intercostal muscles; address rib cage mobility to support respiratory function
- Anterior chest wall scar mobilization — multidirectional glide testing of the mastectomy scar; skin rolling and cross-fiber technique to release tethered scar from pectoralis fascia and ribs; progress from peripheral scar margins toward the most adherent central areas [informed consent required before breast area work]
- Pectoralis major and minor release — sustained compression and myofascial techniques to reduce adaptive shortening; pectoralis minor specifically shortens from protracted posture and contributes to TOS-type symptoms
- Axillary cord management — gentle sustained stretch of visible/palpable cords with the shoulder positioned in progressive abduction; direct gentle longitudinal stroking along the cord from proximal to distal; cords may "snap" or release during treatment — this is expected and beneficial
- Gentle shoulder ROM progression — passive movement through available range, emphasizing abduction and external rotation; respect tissue tolerance and do not force beyond the point of cord tightening [if adhesive capsulitis coexists, follow capsulitis-specific mobilization approach]
- Lymphatic considerations — if early lymphedema signs are present, incorporate MLD principles to the affected arm (light pressure, proximal-to-distal clearing sequence); if no lymphedema, general light effleurage to the affected arm is sufficient
- Reassess shoulder ROM (abduction, flexion, ER) and scar mobility — compare to pre-treatment baseline
Adjunct Modalities
- Hydrotherapy: warm moist heat to posterior shoulder girdle and anterior chest wall before scar and ROM work; avoid heat on the affected arm; cool compresses post-treatment to the axilla if reactive inflammation develops
- Joint mobilization: inferior and posterior GH glide if adhesive capsulitis is contributing to restriction — performed after soft tissue release; scapulothoracic mobilization if scapular mechanics are disrupted; Grade I–II initially, progressing based on response
- Remedial exercise (on-table): active-assisted shoulder abduction and flexion to reinforce ROM gained during treatment; scapular stabilization exercises if winging is present (wall push-ups at tolerable angles); pendulum exercises (Codman's) for early post-surgical patients with limited ROM
Exam Station Notes
- Demonstrate informed consent process before any breast area assessment or treatment
- Show awareness of lymphedema precautions — state that you would avoid deep pressure on the affected arm and check for lymphedema signs
- Distinguish cording restriction from capsulitis on examination — cording restricts primarily in abduction and you can see/feel the cords; capsulitis follows a capsular pattern
- Test for scapular winging to assess long thoracic nerve status
Verbal Notes
- Informed consent: "Before I work on the chest wall area, I want to make sure you're comfortable with that. I'll need to access the tissue around and along your surgical scar to help improve the mobility. You can stop me at any time, and we can adjust the approach to whatever feels right for you."
- Lymphedema education: "The risk of developing lymphedema in your arm is something we need to be mindful of for the rest of your life. I'll always use very light techniques on your affected arm. Please let me know if you notice any new swelling, heaviness, or tightness."
- Cording explanation: "Those tight cords you feel in your armpit are called axillary web syndrome — it's a common complication after lymph node surgery. I'm going to gently stretch and work along those cords. You may feel a pulling or even a small 'snap' — that's actually the cord releasing, and it's a positive sign."
Self-Care
- Daily shoulder ROM exercises: wall climbing (finger walking up a wall), pendulum exercises, and progressive abduction stretching — consistency is critical to prevent ROM loss during scar maturation
- Self-mobilization of chest wall scar: use fingertip pressure to glide the scar in all directions for 5 minutes daily once the scar is fully healed
- Meticulous skin care on the affected arm: moisturize daily, avoid cuts and insect bites, wear gardening gloves, avoid blood pressure cuffs on the affected arm — reduce cellulitis and lymphedema triggers
- Compression garment wear as prescribed if lymphedema is present or at-risk; wear during air travel and vigorous exercise
Key Takeaways
- Mastectomy types range from simple (breast only) to radical (breast, pectoralis muscles, and all axillary nodes); lymphedema risk correlates directly with the extent of lymph node dissection
- Lymphedema is a lifelong risk after axillary surgery; the Stemmer sign is the specific diagnostic test; sentinel node biopsy (1–3% risk) vs. full dissection (5–25% risk) determines the degree of precaution
- Axillary web syndrome (cording) is visible taut cords in the axilla that restrict shoulder abduction — responds well to gentle sustained stretching and manual release
- Long thoracic nerve damage (scapular winging) and intercostobrachial nerve damage (medial arm numbness) are the most clinically significant nerve complications
- Written informed consent is mandatory before any breast area assessment or treatment
- Chest wall scar adhesions to pectoralis fascia and ribs are a primary MT treatment target; adhesion release improves both scar mobility and shoulder ROM
- Post-mastectomy clients may have coexisting lymphedema, cording, and adhesive capsulitis — each requires a different treatment approach, and all three may be present simultaneously
