This book offers clear, accessible information on the causes of cancer and the multiple ways people can reduce their risk for this insidious disease. Like no other work, this much-needed volume gathers the latest research and understanding about the causes of cancer and methods of preventing the disease-and makes it all clear and accessible to the general reader. Cancer Causes and Controversies: Understanding Risk Reduction and Prevention describes common risk factors associated with particular types of cancer, including genetic predisposition, radiation and chemical carcinogens, diet, hormonal factors, infection, and smoking. The book then looks at the scientific evidence supporting the positive role of healthy nutrition, exercise, and diet in lowering cancer risk, as well as the dangers posed by a dysfunctional immune system compromised by chronic infection, unhealthy lifestyles, stress, and poor psychological health. Finally, the book provides an unbiased assessment of a number of controversies surrounding cancer causes and prevention, including screening and genetic testing, vitamin supplementation, genetically modified foods, chemical food additives, and cellular phones and deodorants as potential cancer-causing agents. Primary source materials derived from original scientific work including the National Resources for Molecular Biology (National Center for Biotechnology Information public database) and Cancer Research UK International scientific manuscripts and reviews in the field of cancer research from peer review journals Resources for more information on cancer (websites, association, centers, books)

Medical examiners play an increasingly important role in society as unexpected and violent deaths increase, not only due to crime, but also due to new toxins in the environment, emerging diseases crossing from animals to humans, bizarre suicides, sadistic sexual practices, and other non-natural causes. John Miletich and Tia Lindstrom take us into the world of these medical detectives. Biological clues from bite marks and skin abnormalities to blood chemical levels and brain oxygenation are just some factors exposed in their quest for truth and justice. We learn the basics of death determination from rigor and livor mortis to signs of death by design, drug use, disease, suicide, and more. We also come to understand the tools of this work, from the Stryker's Saw to the grocer's scale, and tests that reveal factors from DNA evidence to toxins from insect bites. Each case begins with a biological mystery and ends with a conclusion that can provide loved ones with relief, or shock.

Miletich, who trained at the Alberta Office of the Chief Medical Examiner and with the Royal Canadian Mounted Police, teams with Lindstrom to introduce readers to the medical examiner's role, including autopsy techniques and analysis. Twists and turns emerge as what was initially thought to be a murder proves to be suicide; what was suspected to be a natural death proves to be murder or environmental poisoning; or what was thought to be an accidental death proves to be something more sinister. This work includes appendices with guides to Medical Examiner organizations, seminars, and conventions.
