Treating Persistent Pain After Breast Cancer Surgery

Breast cancer is one of the most commonly diagnosed cancers among women, and since the prognosis of breast cancer has substantially improved in past decades, complications of management are becoming increasingly apparent. Persistent pain lasting greater than 3 months after breast cancer surgery is unfortunately a common complication affecting approximately 30% of patients after tumour resection. Persistent breast cancer pain has neuropathic features and is typically mild-to-moderate in intensity, with approximately 10% suffering from severe pain. There is an increasing need to prevent persistent pain through the use of transitional pain programmes and perioperative interventions, and to identify novel treatment modalities to reduce suffering in those who unfortunately develop persistent pain. This review serves to provide an overview on persistent pain after breast cancer surgery, its pathophysiology, and current management strategies.
