This book offers a brief overview of the field of oncology in about 200 pages.
It's well-organized: the first few chapters describe the general aspects of epidemiology, pathogenesis, staging and treatment modalities (surgery, systemic therapy and radiotherapy) - I particularly liked chapter 4: communication with cancer patients.
The second part is a guide through the basic information regarding symptoms, staging and treatment of all major cancer types including lung, colorectal, gynecological, CNS, hematological, skin, ...
It's an introduction to clinical oncology (it doesn't go into detail), so someone who is already advanced in this field may therefore be looking for a more detailed text, but for someone in his or her initial stages of learning about clinical aspects of cancer, this would be an excellent choice.
The binding however could have been better since I needed to reinforce some pages with tape (perhaps it is just my copy, I have several other books of OUP and their binding never caused any problems).
