This book is a marvelous compendium of eight articles that cover a wide range of topics, including breast cancer: management and survivorship, rectal cancer intersphincteric resection, head and neck cancer diagnosis and radiotherapy, synthetic peptides as antitumor agents, and recent advances in thyroid cancer. It has been a wonderful opportunity to co-edit this special edition. We are greatly appreciative of the work of all the contributors to the book, who brought with them tremendous diversity of perspectives and fields truly reflective of the complexity of the topic and who, through coming together in this project, serve as a nidus of the multidisciplinary collaboration in this field. Finally, we must acknowledge the thousands of cancer patients who have participated in the studies that have provided the information that has advanced the field so greatly in recent years.
