The Roundtable on Environmental Health Sciences, Research, and Medicine wanted to address the link between environmental factors and the development of cancer in light of recent advances in genomics. They asked what research tools are needed, how new scientific information can be applied in a timely manner to reduce the burden of cancer, and how this can be flexible enough to treat the individual.
Though overall cancer incidence and mortality have continued to decline in recent years, cancer continues to devastate the lives of far too many Americans. In 2009 alone, 1.5 million American men, women, and children were diagnosed with cancer, and 562,000 died from the disease. There is a growing body of evidence linking environmental exposures to cancer. The Pres. Cancer Panel dedicated its 2008¿2009 activities to examining the impact of environmental factors on cancer risk. The Panel considered industrial, occupational, and agricultural exposures as well as exposures related to medical practice, military activities, modern lifestyles, and natural sources. This report presents the Panel¿s recommend. to mitigate or eliminate these barriers. Illus.
Although cancer development and progression depend on stochastic mutational events, the tumor has to be seen in the context of the host environment, and unraveling the environmental factors that support solid tumors is at the root of cancer prevention and cure. This Special Issue, focused on the dynamic crosstalk that occurs between tumor cells and the surrounding microenvironment and also including the cancer cells that represent a reservoir of self-sustaining cells for tumor maintenance, adds new knowledge about tumor–host interactions that is useful for novel diagnostic and therapeutic approaches.
No Family History presents compelling evidence of environmental links to breast cancer, ranging from everyday cosmetics to industrial waste. Sabrina McCormick weaves the story of one survivor with no family history into a powerful exploration of the big business of breast cancer. As drugs, pink products, and corporate sponsorships generate enormous revenue to find a cure, a growing number of experts argue that we should instead increase focus on prevention—reducing environmental exposures that have contributed to the sharp increase of breast cancer rates. But the dollars continue to pour into the search for a cure, and the companies that profit, including some pharmaceutical and cosmetics companies, may in fact contribute to the environmental causes of breast cancer. No Family History shows how profits drive our public focus on the cure rather than prevention, and suggests new ways to reduce breast cancer rates in the future.
The outlook for women with breast cancer has improved in recent years. Due to the combination of improved treatments and the benefits of mammography screening, breast cancer mortality has decreased steadily since 1989. Yet breast cancer remains a major problem, second only to lung cancer as a leading cause of death from cancer for women. To date, no means to prevent breast cancer has been discovered and experience has shown that treatments are most effective when a cancer is detected early, before it has spread to other tissues. These two facts suggest that the most effective way to continue reducing the death toll from breast cancer is improved early detection and diagnosis. Building on the 2001 report Mammography and Beyond, this new book not only examines ways to improve implementation and use of new and current breast cancer detection technologies but also evaluates the need to develop tools that identify women who would benefit most from early detection screening. Saving Women's Lives: Strategies for Improving Breast Cancer Detection and Diagnosis encourages more research that integrates the development, validation, and analysis of the types of technologies in clinical practice that promote improved risk identification techniques. In this way, methods and technologies that improve detection and diagnosis can be more effectively developed and implemented.
Explores the development of the ideas of evolutionary biology, particularly as affected by the increasing understanding of genetics and of the chemical basis of inheritance.
Rhim and Kremer’s state-of-the-art volume on Human Cell Transformation: Role of Stem Cells and the Microenvironment highlights the latest findings on the current state of human cell transformation model systems and provides the insight into the molecular and cellular changes involved in the conversion of normal cells to neoplastic cells. Chapters cover all recently developed novel human cell models. In addition, the rapidly growing fields of knowledge regarding not only stem cells in cancer progression, but also the role of the microenvironments in human carcinogenesis are discussed. A wealth of topics is presented including: · Derivation of epithelial, fibroblastic, and hematopoietic in vitro model systems · Oncogenes · Tumor suppressor genes · Viral transformation · In vitro model systems for viral, chemical and radiation carcinogenesis · Cell aging · The multistep nature of human carcinogenesis · The role of stem cells and the microenvironment in tumorigenesis · The genes involved in multistep carcinogenesis Unique in both scope and focus – devoted solely to human cell transformation systems – Human Cell Transformation: Role of Stem Cells and the Microenvironment provides unparalleled, in-depth coverage for cancer researchers, cell and molecular biologists, hematologists, virologists, and workers in related fields. Essential reading for everyone who needs to be kept up-to-date in this fast-paced area! Features ؠ Multistep models ؠ Breast cancer/Stem cells ؠ Prostate cancer/Stem cells ؠ Multistep / Genes
Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.
The media constantly bombard us with news of health hazards lurking in our everyday lives, but many of these hazards turn out to have been greatly overblown. According to author and epidemiologist Geoffrey C. Kabat, this hyping of low-level environmental hazards leads to needless anxiety and confusion on the part of the public concerning which exposures have important effects on health and which are likely to have minimal or no effect. Kabat approaches health scares as "social facts" and shows that a variety of factors can contribute to the inflating of a hazard. These include skewed reporting by the media, but also, surprisingly, the actions of researchers who may emphasize certain findings while ignoring others; regulatory and health agencies eager to show their responsiveness to the health concerns of the public; and politicians and advocates with a stake in a particular outcome. By means of four case studies, Kabat demonstrates how a powerful confluence of interests can lead to overstating or distorting the scientific evidence. He considers the health risks of pollutants such as DDT as a cause of breast cancer, electromagnetic fields from power lines, radon within residences, and secondhand tobacco smoke. Tracing the trajectory of each of these hazards from its initial emergence to the present, Kabat shows how publication of more rigorous studies and critical assessments ultimately help put hazards in perspective.
