Radiation exposures, both intentional and unintentional, have influence on normal tissue function. Short-term and long-term injuries can occur to all cell systems of both limited and rapid self-renewal potential. Radiation effects can last a lifetime for a patient and can produce complications for all organs and systems. Often invisible at the time of exposure, the fingerprints for cell damage can appear at any timepoint after. Health-care providers will need comprehensive knowledge and understanding of the acute and late effects of radiation exposure and how these interrelate with immediate and long-term care.

Information is exploding at an exponential rate. Because there is a flood of medical information on the Internet, it can be difficult to wade through the many resources to determine what information is best to use in practice. The intent of this chapter in Cancer Concepts: A Guidebook for the Non-Oncologist is to help the health care provider find reliable online cancer information. To help inform clinical decision making, health science librarians continue to address this rapidly growing body of literature by analyzing resources and identifying the highest quality information available on the Internet. The concept of Evidence-Based Medicine (EBM) is important to understand, as well as the process needed to find literature supporting EBM. Why EBM? EBM is "the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients." Making evidence-based clinical decisions is not about intuition, but finding reliable, up-to-date literature and using it in combination with clinical expertise and patient choice. Once a source for free online quality literature is located, a health care provider can consider the best current evidence to thoroughly answer clinical questions.
