In recent years, there have been several important developments in the surgical management of breast diseases, such as new techniques for tumor resection, reconstructive surgery, lymph node assessment, and cosmetic surgery. Lately, the managmenet of breast diseases has received considerable attention in the lay media, and patients today are not only demanding effective surgical treatments, but good cosmetic results as well. Thus, perhaps more than any other field, breast surgery has evolved into both a surgical science and an art. This Atlas describes various surgical techniques for treating diseases of the breast, incorporating both science and art of this unique field. This Atlas provides a trans-Atlantic perspective. The authors are from the United States, Germany, and Italy and have special interest in the treatment of breast diseases. Surgical techniques from both sides of the Atlantic are described, and this should appeal to readers who want to broaden their surgical repertoire. The management of both malignant and benign diseases of the breast is outlined, with illustrations to highlight key aspects of surgical techniques. Particular emphasis is placed on techniques that provide good cosmetic outcomes.
