In Human behavior, including stress and other factors, plays an important role in neoplasia, although too little is known addition, variables which affect cancer development as well on the reasons for such development. Carcinogens, which as some endogenous factors can be better delineated help initiate the neoplastic process, may be either synthetic through such investigations. The topics of this volume encompass premalignant non or naturally-occurring. Cancer causation may be ascribed to invasive lesions, species-specific aspects of carcinogenicity, certain chemicals, physical agents, radioactive materials, viruses, parasites, the genetic make-up of the organism, and radiation, viruses, a quantum theory of carinogenesis, onco bacteria. Humans, eumetazoan animals and vascular plants genes, and selected environmental carcinogens. are susceptible to the first six groups of cancer causes, whe reas the last group, bacteria, seems to affect only vascular plants. Neoplastic development may begin with impairment ofJmdy defenses by a toxic material (carcinogen) which acts as an initiator, followed by promotion and progression to an overt neoplastic state.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book Carcinogens and Anticarcinogens in the Human Diet written by National Research Council and published by National Academies Press. This book was released on 1996-02-12 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite increasing knowledge of human nutrition, the dietary contribution to cancer remains a troubling question. Carcinogens and Anticarcinogens assembles the best available information on the magnitude of potential cancer riskâ€"and potential anticarcinogenic effectâ€"from naturally occurring chemicals compared with risk from synthetic chemical constituents. The committee draws important conclusions about diet and cancer, including the carcinogenic role of excess calories and fat, the anticarcinogenic benefit of fiber and other substances, and the impact of food additive regulation. The book offers recommendations for epidemiological and diet research. Carcinogens and Anticarcinogens provides a readable overview of issues and addresses critical questions: Does diet contribute to an appreciable proportion of human cancer? Are there significant interactions between carcinogens and anticarcinogens in the diet? The volume discusses the mechanisms of carcinogenic and anticarcinogenic properties and considers whether techniques used to evaluate the carcinogenic potential of synthetics can be used with naturally occurring chemicals. The committee provides criteria for prioritizing the vast number of substances that need to be tested. Carcinogens and Anticarcinogens clarifies the issues and sets the direction for further investigations into diet and cancer. This volume will be of interest to anyone involved in food and health issues: policymakers, regulators, researchers, nutrition professionals, and health advocates.

Available in PDF, EPUB and Kindle. Book excerpt: In November 1997, an expert group was convened to discuss available knowledge on the epidemiology, pathology and mechanisms related to certain tumors that are commonly seen in essays for carcinogenicity in rodents in order that their importance in human hazard evaluation might be assessed. The tumors of interest were urinary bladder carcinomas associated with urolithiasis, microcrystalluria and certain urinary precipitates; renal corticol tumors in male rats associated with alpha-2 urinary globulin nephropathy; and thyroid follicular cell tumors associated with imbalances in thyroid stimulating hormone. Included in the book are a series of individually authored papers on these various topics, as well as a Concensus Report including consideration of how such data may be used within the evalation process in the IARC Monographs on the Evaluation of Carcinogenic risks to Humans.
Download or read book Issues in Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific basis, inference assumptions, regulatory uses, and research needs in risk assessment are considered in this two-part volume. The first part, Use of Maximum Tolerated Dose in Animal Bioassays for Carcinogenicity, focuses on whether the maximum tolerated dose should continue to be used in carcinogenesis bioassays. The committee considers several options for modifying current bioassay procedures. The second part, Two-Stage Models of Carcinogenesis, stems from efforts to identify improved means of cancer risk assessment that have resulted in the development of a mathematical dose-response model based on a paradigm for the biologic phenomena thought to be associated with carcinogenesis.

Download or read book Health Risks from Exposure to Low Levels of Ionizing Radiation written by Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation and published by National Academies Press. This book was released on 2006-03-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.
Download or read book Peroxisome Proliferation and Its Role in Carcinogenesis written by and published by World Health Organization. This book was released on 1995 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: A state-of-the-art consensus report on what is known about peroxisome proliferation, the mechanisms involved, and their relevance to carcinogenesis. Peroxisomes are single, membrane-limited, cytoplasmic organelles that are found in cells of animals, plants, fungi, and protozoa. Peroxisome proliferators include certain hypolipidaemic drugs, phthalate ester plasticizers, industrial solvents, herbicides, food flavours, leukotriene D4 antagonists, and hormones. Numerous studies in rats and mice have demonstrated the hepatocarcinogenic effects of peroxisome proliferators, and these compounds have been unequivocally established as carcinogens. Since humans are exposed to peroxisome proliferators to a significant extent, assessment of the adverse biological effects of this group of compounds, and particularly their potential carcinogenicity, has become an important issue. The report has two parts. The first records the consensus reached by a group of eleven experts, including several of the leading investigators in this field. Questions addressed include the mechanisms by which peroxisome proliferators exert their carcinogenic effects in rodents, the relevance of animal studies to the evaluation of carcinogenic risk in humans, and the potential use of peroxisome proliferation as a biological marker for liver cancer. The report concludes that compounds inducing peroxisome proliferation in rats and mice have little, if any, effect on human liver. The report also issues advice on the interpretation of peroxisome proliferation, demonstrated in animal studies, when evaluating the carcinogenic risk to humans. The second part consists of three background papers presented by members of the working group.
Download or read book Tumour Site Concordance and Mechanisms of Carcinogenesis written by Robert A. Baan and published by International Agency for Research on Cancer. This book was released on 2019-05-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Scientific Publication reviews the information on cancer sites and mechanistic events for the more than 100 agents classified in Group 1 (carcinogenic to humans) by the IARC Monographs Program. This category of agents is diverse and includes chemicals and chemical mixtures; occupations; metals, dusts, and fibres; radiation; viruses and other biological agents; personal habits; and pharmaceuticals. For the Group 1 agents, there were cross-cutting questions about the relevance to humans of certain cancer sites or mechanistic pathways in animals. This publication is based on a systematic identification and comparison of the cancer sites observed in humans and those observed in experimental animals, and a compilation of mechanistic events for agents known to cause cancer in humans. Relevant information was analyzed on all the agents classified in Group 1 in Monographs up to and including Volume 109, most of which are reviewed in Volume 100A-F. A database of tumor sites seen in humans and animals was used to examine the degree of concordance by use of an anatomically based tumor classification scheme. The analysis of mechanistic aspects of the IARC Group 1 agents focused on 10 key characteristics of human carcinogens developed during the course of this work. Genotoxicity was the most prevalent mechanistic characteristic, consistent with the process of carcinogenesis necessarily involving genomic changes. The IARC concordance database represents a useful source of information for comparing animal and human data with respect to the tumors caused in different species. The results of the mechanistic analysis can provide a basis for future efforts to categorize mechanistic data for carcinogens through a systematic review process. These reviews and analyses were discussed during a two-part Workshop on Tumour Site Concordance and Mechanisms of Carcinogenesis convened by IARC. This Scientific Publication is the report of that Workshop and of subsequent work by the participants, both individually and collectively. This publication also presents a statement of consensus among the Workshop participants, which summarizes the main findings and their implications for human cancer risk assessment.
Download or read book Chemical Carcinogenesis written by Trevor M. Penning and published by Springer Science & Business Media. This book was released on 2011-03-03 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume will provide a contemporary account of advances in chemical carcinogenesis. It will promote the view that it is chemical alteration of the DNA that is a route cause of many cancers. The multi-stage model of chemical carcinogenesis, exposure to major classes of human carcinogens and their mode-of-action will be a focal point. The balance between metabolic activation to form biological reactive intermediates and their detoxification, ensuing DNA-lesions and their repair will be profiled. It will describe the chemical changes that occur in DNA that result from endogenous insults including epigenetic changes that lead to gene silencing. It will describe major mechanisms of mutagenesis, affects on tumor suppressor genes and proto-oncogenes, and how cell-cycle check points can be by-passed by the "stealth-like" properties of chemical carcinogens. Environmental agents that can promote tumor formation will be discussed. The monograph will have wide appeal as a knowledge base for graduate students, post-doctoral fellows and faculty interested in this aspect of cancer causation and research.
