Post-Mastectomy Exercises: Restore Arm and Shoulder Function

After mastectomy or breast cancer surgery, your arm and shoulder need careful rehabilitation. Surgery affects muscles, lymph nodes, and nerves, leading to tightness, weakness, and risk of lymphedema. The right exercises—started at the right time—restore function, reduce complications, and help you return to normal activities.

Understanding Post-Mastectomy Recovery

Breast surgery affects more than breast tissue:

Surgical impacts:

• Chest muscles cut or moved (especially with reconstruction)
• Lymph nodes removed (axillary dissection)
• Skin tightness from incisions
• Nerve damage (numbness, tingling common)
• Drain tubes initially limiting movement

Potential complications:

• Frozen shoulder (adhesive capsulitis)
• Cording (axillary web syndrome)
• Lymphedema (arm swelling)
• Postural changes
• Chronic pain

Exercise goals:

• Restore full shoulder range of motion
• Prevent frozen shoulder
• Reduce lymphedema risk
• Rebuild strength
• Improve posture

When to Start Exercises

Important: Follow your surgeon's specific instructions. General timeline:

Days 1-7 (Drains in):

• Deep breathing exercises
• Walking
• Gentle hand and wrist movements
• Limited shoulder movement (usually below 90 degrees)

Week 1-2 (After drains removed):

• Begin gentle range-of-motion exercises
• Progress as surgeon allows

Weeks 2-6:

• Progressive stretching
• Full range-of-motion work
• Begin gentle strengthening

Weeks 6+:

• Continue stretching
• Progressive strengthening
• Return to activities

Lymphedema Prevention

If lymph nodes were removed, take precautions:

During Exercise

• Wear compression garment if recommended
• Progress gradually—don't suddenly increase intensity
• Monitor arm for swelling after exercise
• Stop if arm feels heavy or achy

Daily Precautions

• Avoid blood pressure, injections, blood draws in affected arm
• Wear gloves for gardening
• Use sunscreen (avoid burns)
• Avoid tight jewelry or clothing on arm
• Moisturize skin to prevent cracks

Self-Massage (Lymphatic Drainage)

1. Start at neck—light strokes toward heart
2. Move to armpit area—light circular movements
3. Work up the arm from fingers toward armpit
4. Very light pressure—like petting a cat
5. Do daily, especially if noticing any swelling

Cording (Axillary Web Syndrome)

Tight cords under the skin from armpit down arm are common:

Symptoms:

• Visible tight bands under skin
• Pain with stretching
• Limited arm movement

Treatment:

• Continue stretching (gently)
• Massage along the cords
• Physical therapy if severe
• Usually resolves in weeks to months

Sample Daily Routine

1. Deep breathing: 10 breaths
2. Wall climbing: 10 reps
3. Side wall climbing: 10 reps
4. Wand overhead lift: 10 reps
5. Shoulder circles: 10 each direction
6. Corner stretch: 3 × 20 seconds

Evening (15 minutes)

When to Contact Your Doctor

Call if you notice:

• Increasing redness, warmth, or swelling at incision
• Fever
• New drainage or opening of incision
• Significant increase in arm swelling
• Severe pain not controlled by medication
• Signs of infection

Long-Term Considerations

Continue exercises:

• Stretching remains important long-term
• Maintain strength and flexibility
• Monitor for lymphedema indefinitely

Return to activities:

• Discuss specific activities with your surgeon
• Return to exercise gradually
• Avoid heavy lifting on affected side initially
• Swimming is excellent when cleared

Emotional recovery:

• Physical activity improves mood
• Support groups can help
• Be patient with your body

The Bottom Line

Post-mastectomy rehabilitation is essential for full recovery:

1. Start early - As soon as surgeon allows
2. Be consistent - Daily exercises work best
3. Progress gradually - Don't rush
4. Protect against lymphedema - Take precautions seriously
5. Be patient - Full recovery takes months

Your body has been through a lot. With consistent, gentle exercise, you can restore your arm and shoulder function, reduce complications, and return to the activities you love. Take it one day at a time, and celebrate each small victory along the way.
