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. It includes research on (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 aetiology and prevention.
