The Biology of Cancer is a new textbook for undergraduate and graduate biology students as well as medical students studying the molecular and cellular bases of cancer. The book presents the principles of cancer biology in an organized, cogent, and in-depth manner. The clarity of writing and the lucid full-color art program make the book accessible and engaging. The information unfolds through the presentation of key experiments, which give readers a sense of discovery, and provide insights into the conceptual foundation underlying modern cancer biology. A CD-ROM packaged with the book contains figures from the book, additional sidebars from the text, movies, and audio files of mini-lectures.  Besides its value as a textbook, The Biology of Cancer will be a useful reference for individuals working in biomedical laboratories and for clinicians.
