The amount of cancer-related information available in the media and other sources continues to increase each year. We wondered how people make use of such content in making specific health decisions. We studied both the information they actively seek (seeking) and that which they encounter in a less purposive way (scanning) through a nationally representative survey of adults aged 40-70 years (n=2,489) focused on information use around three prevention behaviors (dieting, fruit and vegetable consumption, and exercising) and three screening test behaviors (prostate-specific antigen, colonoscopy, mammogram). Overall, respondents reported a great deal of scanning and somewhat less seeking (on average 62% versus 28% for each behavior), and they used a range of sources including mass media, interpersonal conversations, and the Internet, alongside physicians. Seeking was predicted by female gender, age of 55-64 vs. 40-44, higher education, Black race and Hispanic ethnicity, and being married. Scanning was predicted by older age, female gender, and education. Respondents were fairly consistent in their place on a typology of scanning and seeking across behaviors. Seeking was associated with all six behaviors, and scanning was associated with three of six behaviors.
