Post-Mastectomy Physiotherapy: Restoring Arm and Shoulder Function

The Physical Impact of Breast Surgery

Breast cancer surgery, whether lumpectomy, mastectomy, or mastectomy with reconstruction, affects far more than the breast tissue. The surgery involves cutting through chest muscles, removing lymph nodes from the armpit, and creating scar tissue that can restrict shoulder movement for months or years if not properly managed. In Penang, oncology centres at Penang General Hospital, Gleneagles, and Loh Guan Lye perform hundreds of breast surgeries annually.

Many women are surprised by the extent of shoulder and arm problems that develop after breast surgery. Reduced shoulder range of motion, arm weakness, tightness across the chest, and the risk of lymphoedema – chronic swelling of the arm – are common complications that significantly affect quality of life. Early physiotherapy intervention, ideally starting before surgery with pre-operative education, produces the best outcomes for shoulder recovery and lymphoedema prevention.

Early Post-Surgical Rehabilitation

Physiotherapy typically begins within the first week after surgery, even while drains are still in place. Initial exercises are gentle and focused on maintaining basic shoulder and arm movement to prevent the adhesions and scar tissue contracture that develop rapidly in the first few weeks. Gentle shoulder rolls, elbow bends, wrist circles, and hand squeezes keep the arm active without stressing the surgical site.

Your home visit physiotherapist will teach you deep breathing exercises to maintain respiratory function, as women often breathe shallowly after chest surgery due to pain. Posture education is equally important – many women adopt a protective rounded posture, drawing the affected shoulder forward and guarding the chest, which leads to chronic neck and upper back pain if not addressed. Scar massage, beginning once the wound has healed, prevents the tight, adhered scars that restrict shoulder movement.

Restoring Shoulder Range of Motion

The most common post-surgical limitation is difficulty lifting the arm above shoulder height. This occurs because of surgical tightness in the chest muscles, axillary web syndrome, or cording, where tight bands develop in the armpit and inner arm, and protective muscle guarding. Without treatment, these restrictions can become permanent.

Your physiotherapist will guide you through progressive shoulder exercises: wall walks where your fingers climb up a wall to gradually increase overhead reach, pulley exercises using a rope over a door to assist lifting the affected arm, and gentle stretches to elongate the chest muscles and scar tissue. If axillary cording is present, specific manual therapy techniques can release these tight bands, often producing dramatic immediate improvement in arm elevation. Progress is measured objectively at each session, ensuring that range of motion is steadily improving toward full function.

Lymphoedema Prevention and Management

Lymphoedema, the chronic swelling of the arm and hand caused by disrupted lymphatic drainage after lymph node removal, affects 20 to 30 percent of breast surgery patients. While not all cases can be prevented, early identification and management significantly reduce severity. Your physiotherapist will teach you the signs to watch for: a feeling of heaviness in the arm, rings or watch feeling tighter, visible swelling, reduced flexibility, and skin changes.

Prevention strategies include arm elevation during rest, avoiding blood pressure cuffs and blood draws on the affected arm, wearing sunscreen and insect repellent to prevent skin infections that trigger lymphoedema, and performing daily manual lymphatic drainage – gentle massage techniques that encourage lymph fluid to drain through alternative pathways. If lymphoedema develops, your physiotherapist will implement complete decongestive therapy including bandaging, specialised massage, exercise, and skin care. Home visit physiotherapy allows this specialised treatment to be delivered conveniently in your Penang home.

Rebuilding Strength and Confidence

As range of motion improves and the surgical site heals, strengthening exercises become the focus. Rebuilding chest, shoulder, and arm strength is essential for returning to normal daily activities. Progressive resistance exercises using light weights and resistance bands target the muscles affected by surgery without overloading the healing tissues.

Cardiovascular fitness, which often declines during cancer treatment, is gradually rebuilt through walking programmes and, when appropriate, swimming. Exercise during and after cancer treatment has been shown to reduce fatigue, improve mood, and may even reduce the risk of cancer recurrence. For Penang women who previously enjoyed activities like gardening, cooking, or carrying grandchildren, your physiotherapist will work toward these specific functional goals, building the strength and confidence needed to resume the activities that bring joy and purpose.

Emotional Support and Long-Term Follow-Up

Breast cancer treatment is an emotionally challenging journey, and the physical changes to the body can significantly impact self-image and confidence. Your home visit physiotherapist provides a safe, private space to address these concerns during rehabilitation. The therapeutic relationship built over weeks of home visits often allows patients to express worries and frustrations they might not share in a busy hospital setting.

Long-term follow-up is important because lymphoedema can develop months or even years after surgery. Your physiotherapist will recommend periodic reassessment, particularly if you notice any changes in arm size or sensation. For Penang women who have completed their cancer treatment, maintaining the exercise programme prescribed during rehabilitation provides ongoing physical and psychological benefits. Support groups and community resources available through Penang’s cancer support organisations provide additional peer support that complements the professional care of your physiotherapy team.
