Cording after breast cancer surgery
A clear look at axillary web syndrome — what it is, why it happens, and how therapy helps you reach, dress, and move comfortably again.

What is cording (axillary web syndrome)?
Cording is one or more tight, rope-like bands that can form under the arm — sometimes extending toward the elbow or wrist — after lymph node surgery or radiation. The bands can limit shoulder motion and feel tight or painful when you reach overhead.
Why does it happen?
Cording is thought to involve irritation or scarring of the lymphatic and connective tissue after surgery. It can appear within days or develop weeks later, and it’s common — many people simply aren’t told to expect it.
Does cording go away on its own?
It can ease over time, but targeted physical therapy usually restores motion faster and more comfortably than waiting. Gentle manual techniques, stretching, nerve and tissue mobility work, and a guided home program are the core of care.
How physical therapy helps
- Gentle manual therapy to release the cords and surrounding tissue
- Stretching and shoulder-mobility work, progressed safely
- Scar-tissue management and myofascial release
- A home program so gains hold between visits
- Lymphedema-risk awareness throughout, from a Certified Lymphedema Therapist
Cording care is part of breast cancer rehabilitation, and connects closely to lymphedema therapy.
A note: general education, not medical advice. New or painful cording should be evaluated by your care team.
