Description Breast cancer is the most frequent malignancy of middle age women (%32) and causes 19% of cancer-related deaths. Acute pain can contribute to the development of persistent surgical pain. Persistent postsurgical pain has been demonstrated to be clinically relevant in 10% to 50% of patients undergoing various common operations, including breast cancer surgery. The pathogenic mechanisms are multiple, including nerve damage related to surgical technique resulting in risk of intercostobrachial neuralgia, neuroma pain, or phantom breast pain. Multimodal analgesic strategies are important.Glucocorticoid steroids can also provide beneficial effects when administered in appropriate doses as part of a multimodal analgesic regimen in the perioperative setting. A recent study demonstrated that preoperative application of dexamethasone reduced postoperative nausea and vomiting and pain in patients after thyroidectomy.. It is possible that the already established reduction in prostaglandin synthesis mediated by dexamethasone contributes to the analgesia. And also there are a lot of mechanisms more.
