ABOUT THE BOOKTo simplify the causes of cancer, the ATSDR (Agency for Toxic Substances & Disease Registry) divides causes into factors outside the body and factors inside the body. The processes and problems inside your body are automatic and largely outside of your control, so there isn't much you can do to control them or stop cancer cells which may spring up from related issues. Think of the way your hair grows, or the way your face starts to form wrinkles as you age. Internal causes are similar, but result from mutations in such common biological processes.However, the other major category of cancer-makers is all the factors outside your body, a host of different activities or practices which can tip the scales toward certain types of cancer. While internal sources of cancer can't be helped, these external causes can be changed by direct intervention. In other words, you can make a difference, especially when it comes to what you eat and how well you take care of your body.MEET THE AUTHORTyler Lacoma writes on business, environmental, and fitness topics, but squeezes in some time for fiction, too. He graduated from George Fox University and lives in beautiful Oregon, where he fills spaces between writing with outdoor fun, loud music, and time with family and friends.EXCERPT FROM THE BOOKIf diet and lifestyle aren't the only indicators of cancer risk, what else is? Amidst numerous potential causes, research has narrowed down several other leading factors which may cause cancer no matter the lifestyle you lead. Do not expect new diets and activities to remove all possibilities of cancer. Heredity is a classic internal cause, because it lies solely within your DNA. Until advanced gene therapy is possible, there's not much you can do about it.Although it is technically an external factor, chronic inflammation joins heredity as an additional cause often beyond your control. The swelling and damage associated with long-term inflammation can, over time, become a sort of breeding ground for cancerous cells. Typically, stubborn viruses or bacterial infections dig in deep and generate this type of inflammation. They crop up more often in developing countries with hygienic struggles.There are also a number of environmental causes more connected with necessity than lifestyle choices. "Past occupational exposure" makes it on many cancer lists because manufacturing work can expose people to cancer-causing toxins and vapors. But a job is a job, and often beyond the control of the worker. Likewise, lung cancer has been irrefutably linked to radon, the radioactive element in air, but radon levels are determined by things like the location of your house and its material composition -things not exactly easy to change...Buy a copy to keep reading!
