乳腺癌是一种全身性疾病 ,往往在病变的早期即可能发生远处转移。当今乳腺癌治疗的观念从单一的外科手术治疗转变为全身的综合治疗。目前治疗乳腺癌的趋势是手术范围越来越小 ,采用小手术大放疗的方法 ,达到保留乳房美观的作用 ;通过采用术前新辅助化疗 ,使手术适应证越来越宽 Breast cancer is a systemic disease, and distant metastases may occur in the early stages of the disease. The concept of breast cancer treatment today shifts from a single surgical treatment to a comprehensive systemic treatment. The current trend in the treatment of breast cancer is that the scope of surgery is getting smaller and smaller, and small radiosurgery and large radiotherapy are used to preserve the aesthetic appearance of the breast. By using preoperative neoadjuvant chemotherapy, the indication for surgery is becoming wider and wider.
