This book presents the latest research on advances in genetics, molecular medicine, biotechnologies, and behavioural sciences that have an impact on primary, secondary and tertiary cancer prevention including: (a) Basic mechanisms of neoplastic diseases leading to the identification of molecular pathways that can be employed as targets for cancer prevention; (b) Descriptive, analytical, and molecular epidemiology with emphasis on developing biomarkers of cancer risk assessment and response to cancer prevention; (c) Laboratory and clinical procedures for prognostic evaluation of malignant tumour transformation, progression and response to treatment with cancer preventive agents; (d) Discoveries of natural substances and synthetic agents that have promising cancer preventive potential and elucidating their mechanistic action; (e) Development and assessment of cancer preventive approaches that have potential for being translated into the clinic; (f) Cancer prevention pre-clinical studies and clinical trials; (g) Patient management and education, management of curable lesions, education and lifestyle modification and the role of behavioural factors in cancer etiology and prevention.
