Memorial Sloan-Kettering physical therapy expert Laryssa Buoneto describes an exercise regimen for women who have had breast surgery without reconstruction. These exercises will help you regain range of motion in the arm on the side where you had surgery. This means you will be able to move your arm above your head, out to your side, behind your neck, and to the middle of your back. Exaggerated deep breathing can help you relax and ease discomfort or tightness as you perform these exercises.
Continuing the exercises after you regain full range of motion will also help to prevent scar tissue from forming in your armpit and shoulder.
