**Preface to "Effect of Diet and Physical Activity on Cancer Prevention and Control"**

Close to 20 million people around the world are diagnosed with cancer on an annual basis. Thus, there is no doubt that the burden of cancer is significant, and it is a leading cause of morbidity and mortality worldwide. Diet, physical activity, and weight management are increasingly recognized as key factors that can influence cancer prevention, progression, and survival. Moreover, these lifestyle factors also play an important role in mitigating symptoms and comorbidities that result from cancer and its treatment. As nutrition and exercise scientists, we are delighted to be joined by others who devote their careers to the discovery of novel dietary and physical activity-related factors, as well as interventions aimed at cancer prevention and control. It is our pleasure to serve as editors for this book, and we are grateful to all the researchers who have submitted their scientific findings to be included in this compendium. We also are grateful to the managing editors who helped to assemble this important work, Ms. Lindsey Guo and Toki He. As you will find, the order of articles follows the cancer continuum. The book begins with the role of diet and exercise in the primary prevention of cancer in both normal and high-risk individuals and then focuses on preventing neoplastic progression in those who are newly diagnosed with the disease. Later chapters center on dietary and physical activity as key factors in cancer survivorship, finally concluding with works attributing dietary and physical activity factors on cancer survival. We hope that you will enjoy and value these offerings.
