Published June 2, 2025

Patients who undergo surgery or radiation after breast cancer may have issues that involve scar tissue and tightness of the chest and upper back muscles.

Below are stretches and exercises from the Straub Benioff Medical Center Physical and Rehabilitation Therapy team to help women regain movement, reduce stiffness, and improve strength.

These exercises are designed to be gentle and should be performed slowly and carefully. They are ordered starting with the easiest and progress in difficulty/complexity.

While these stretches are a good complement to breast cancer treatment, they can be useful to anyone who wants to improve their posture or increase functional mobility in their neck, shoulders, and upper back.

If you experience pain or discomfort beyond mild stretching sensations, stop immediately and consult your health care provider.

Getting Started: When to Begin

Before starting any rehabilitation exercises, consult your doctor or physical therapist to ensure that you're ready. In many cases, light exercises can begin soon after surgery, but it is extremely important to proceed gradually and listen to your body.

1. Deep Breathing

Purpose: Promotes relaxation and improves lung function after surgery or radiation.

  • Sit or lie in a comfortable position.
  • Place one hand on your abdomen and the other on your chest.
  • Take a slow, deep breath through your nose, allowing your abdomen to rise.
  • Exhale slowly through pursed lips, feeling your abdomen fall.
  • Repeat 5-10 times, several times a day.

  • Gently bring your shoulder blades together, toward your spine.
  • Hold for 5-10 seconds, then relax.
  • Repeat 5-10 times.
