Oncology is a medical specialty taught less well during the undergraduate and junior postgraduate years, hence new trainees often find it difficult to understand the basic concepts of cancer practice.

The contents give a concise account of the multidisciplinary management of common cancers and cancer-related problems appropriate to doctors at the start of their careers in this specialty. The content of the book will be based on latest available evidence and will also reflect the training guidelines.
