Low-Level Laser Therapy (LLLT) can help relieve pain, soften cords, and restore mobility in Axillary Web Syndrome by promoting healing and reducing tissue tightness.

What is AWS?

Axillary Web Syndrome (AWS, sometimes called cording) often develops after breast cancer surgery involving lymph node removal. It presents as tight, painful cord-like bands under the skin, usually in the armpit extending down the arm, and can limit shoulder range of motion.

Cording is referred to as a Lymphatic collectors as it is related to the lymphatic system and can restrict movement. This pain and limited range of motion can have a major impact on your day-to-day life.

Low-Level Laser Therapy (LLLT) — also called Photobiomodulation Therapy (PBMT) — has been investigated as a supportive treatment for AWS.

HOW DOES LLLT HELP?

Reduces pain & inflammation: LLLT can downregulate pro-inflammatory cytokines and increase blood flow, leading to reduced tenderness and swelling in the axilla/arm.

Improves tissue healing: By stimulating mitochondrial activity and ATP production, LLLT can accelerate soft tissue repair and reduce fibrosis.

Enhances lymphatic flow: Photobiomodulation may support lymphangiogenesis (growth of new lymphatic vessels) and improve local lymphatic drainage, potentially easing tension on cords.

Softens fibrotic cords: AWS cords are thought to involve thrombosed lymphatic vessels and fibrosed tissue. LLLT can help remodel collagen and soften these cords, improving tissue elasticity.

We strongly recommend beginning LLLT treatment as early as possible, ideally at the first signs of cording.
