Introduction to Oral Cancer: Etiology and the Role of Tobacco

Introduction to Oral Cancer – Etiology and the Role of Tobacco provides a detailed and systematic exploration of oral cancer, its causes, mechanisms, clinical manifestations, and preventive approaches. The book begins with an overview of oral anatomy and the epidemiology of oral cancer at global and national levels, highlighting the increasing disease burden associated with tobacco use.
The text examines the pathophysiology of oral carcinogenesis, focusing on how carcinogenic compounds present in tobacco products initiate cellular and genetic changes leading to malignant transformation. Various forms of tobacco consumption, including smoking and smokeless tobacco, are discussed along with their chemical composition and associated health risks.
The book also covers risk factors such as alcohol use, human papillomavirus (HPV) infection, poor oral hygiene, and nutritional deficiencies. Detailed discussions on signs and symptoms, diagnostic procedures, staging, histopathological changes, and treatment approaches provide clinical insight into disease management.
In addition, the text emphasizes public health interventions, anti-tobacco policies, screening programs, and awareness initiatives aimed at prevention and early diagnosis. Designed for students of medical, dental, nursing, and allied health sciences, this book serves as both an introductory guide and a practical reference for understanding oral cancer and tobacco-related health hazards.
