There is growing scientific consensus that mammography has a modest impact on averting deaths from breast cancer, while exposing women to a number of harms.1 Yet it is not well known how women in the general US public perceive the benefits and harms of mammography screening. Previous research has been published on public enthusiasm for screening and underestimates of harms, but these findings may be outdated.24 In this study, we present 2016 data on women’s awareness and perceptions of the benefits and harms of mammography, drawn from a larger survey of US adults on exposure to cancer-related information in the media.
