This article challenges the idea that cancer cannot be prevented among older adults by examining different aspects of the relationship between age and cancer. Although the sequential patterns of aging cannot be changed, several age-related factors that contribute to disease risk can be. For most adults, age is coincidentally associated with preventable chronic conditions, avoidable exposures, and modifiable risk behaviors that are causally associated with cancer. ⋯ Interventions that support healthy environments, help people manage chronic conditions, and promote healthy behaviors may help people make a healthier transition from midlife to older age and reduce the likelihood of developing cancer. Because the number of adults reaching older ages is increasing rapidly, the number of new cancer cases will also increase if current incidence rates remain unchanged. Thus, the need to translate the available research into practice to promote cancer prevention, especially for adults at midlife, has never been greater.

As part of setting the stage for this supplement to the American Journal of Preventive Medicine, a life-course perspective is presented to assist in understanding the importance of cancer prevention for adults in midlife, a period roughly spanning 20 years between ages 45 and 64 years. Drawing on disciplinary perspectives from the social sciences and public health, several life-course themes are delineated in this article: how specific life transitions present unique opportunities for interventions to inform policy and practice that can improve population health outcomes; how interventions can be focused on those at particular life stages or on the entire life course; and how the onset and progression of chronic conditions such as cancer are dependent on a complex interplay of critical and sensitive periods, and trajectory and accumulation processes. ⋯ Specifically, cancer-related risks and care networks are examined, with examples of public health strategies that can be applied to cancer prevention and control. As a conclusion, select methodologic issues and next steps for advancing research and practice are identified.

The International Agency for Research on Cancer determination that shift work is a "probable" human carcinogen was based primarily on studies of breast cancer but it was also noted that additional aspects of circadian disruption and other cancer sites deserved further research. ⋯ In this large prospective study, there was a higher risk of fatal ovarian cancer in women who reported a rotating work schedule. These findings and the high prevalence of rotating shift schedules underscore the need for further research examining the role of work schedule and risk of ovarian cancer.

More than 80% of U.S. adults use the Internet, 65% of online adults use social media, and more than 60% use the Internet to find and share health information. ⋯ Information presented on the Internet by state-sponsored tobacco control programs remains modest and limited in interactivity, customization, and search engine optimization. These programs could take advantage of an important opportunity to communicate with the public about the health effects of tobacco use and available community cessation and prevention resources.

The workplace is an important domain for adults, and many effective interventions targeting physical activity and weight reduction have been implemented in the workplace. However, the U.S. workforce is aging, and few studies have examined the relationship of BMI, physical activity, and age as they relate to workplace characteristics. ⋯ These findings underscore the persistent impact of the work environment for workers of all ages. Based on these results, programs or policies aimed at improving the work environment, especially decision latitude, job flexibility, and workplace harassment should be included in the design of worksite-based health promotion interventions targeting physical activity or obesity.
