Salient Features: Principles and Management of Cancer tries to bridge the gap in the practices of cancer treatment in a holistic manner. Oncology, or the study of cancer, includes cancer genomics, cell biology, tumor pathology, staging, investigations, and treatment of patients suffering from cancer. The approach of the book is to arrange the chapters according to different sites and to present a supportive literature on surgical principles, radiation-therapeutics, and chemotherapeutic management of cancers. The book provides an insight into the radiobiological principles of radiation therapy, newer techniques of laser and minimally invasive surgery, critical organ sparing treatment delivery in radiation therapy, nutritional support for a cancer patient and guidelines on pain management. Acute emergencies have been dealt with as a separate chapter without any attempt to cover the critical care of such cases. The chapter on clinical trials is a guideline on such a complex subject and gives a clue to the drug development process. The need for multi modality treatment to cure cancers and minimizing toxicity is emphasized throughout the book. Radiation therapy is the principal method of treating cancer patients and this book highlights the stages of cancers where radiation can provide optimal benefit alone or as an adjunct to surgery and/or antineoplastic agents. The book aspires to serve as a ready reference for the students of oncology, practitioners, clinicians, general physicians and oncologists. We hope it finds a space on the book shelf of the healthcare givers reaching out to cancer patients.
