Brief Summary
Chronic pain after Mastectomy is frequent and an important healthcare priority because of its effect on quality of life. Although the association between the severity of acute pain after surgery and the likelihood of chronic pain is known, their causal relationship has not been clarified. Mastectomy, frequently done for the management of breast cancer, is associated with significant acute postoperative pain and limited shoulder movement.
