From the reviews: This book is aimed directly at cancer researchers, delving into the various technologies used to identify and characterize these rare tumor cells. ... this is the first book to summarize the progress in this field. It charts the evolution in thinking about breast cancer from the Halstedian notion of a local disease to more of a systemic illness in an accessible way and nicely summarizes the data without overwhelming readers.
