Tumour is a lethal disease in this world. There are many possible approaches to treating tumours, such as immunotherapy, chemotherapy and biochemotherapy. Nowadays, many clinicians and researchers develop methods to deal with this disease. Basic concepts and mathematical analysis of tumour therapy present in this book. Simulation of the tumour therapy also presents in this book. This book is relevant to students and researchers who studying about tumour therapy or clinicians that doing experiment tumour therapy. This book will help students and researchers to understand the process of tumour therapy and will give the benefit for clinicians in predicting results through mathematical modeling prior to commencing treatment on human subjects, it will minimize the dangerous effect and the cost of treatment.
