This book was written to fill a perceived void in the current literature. Cutaneous Oncology is designed to focus on the nature and behaviour of cancers, standing at the junction of clinical medicine and basic science research to provide a whole picture of skin tumor biology to both clinicians and researchers. The book explains our clinical understanding of skin cancers in terms of their biological and molecular bases, and provides a framework of clinical settings in which to understand and appreciate the importance of individual facets of tumor biology.
