The book focuses on the understanding of molecular pathways by which normal cell progress to the definable stage of cancer. The chapters explore microbiota and chronic inflammation, multiple myeloma chemoprevention, microRNAs, cancer regulation, liquid biopsies, and angiogenesis. Recent advances of molecular risk assessment, tumor microenvironment, microneoplasia, malignant gene expressions are highlighted to provide a means and design of future cancer prevention strategies and challenges thereupon. The volume also explores various receptor drugs that are in development process with the emphasis of inhibitors used to prevent malignant gene expression. The book bridges the gap between basic science and clinical application of current knowledge of cancer and emphasizes that tumor progression and cancer metastasis are not random - treatments and cure are logical and eventual.
