The Third International Copenhagen Symposium on Detection of Breast Cancer afforded a further opportunity for scientists from all over the world to come together and present important papers con­ cerning breast cancer and early diagnostic procedures. The Sympo­ sium was an opportunity to learn from extensive screening proce­ dures carried out at outstanding centers in the United States, Sweden, the Netherlands, and England. Furthermore, the Sympo­ sium dealt with new modalities such as ultrasonography, magnifi­ cation techniques, and magnetic resonance; and very important contributions concerning self-examination, fine needle aspiration biopsy, and radiation risks were presented. A whole section was also dedicated to the highly important cooperation between radiologist, surgeon, and pathologist. It is our sincere hope that a study of the different aspects of breast cancer presented in this volume will encourage the reader to join in the struggle against this dreadful dis­ ease.
