The objective of this program was to increase mammography screening rates among Hispanic women through a series of targeted community-wide interventions. A diverse array of outreach efforts was offered by the program to increase awareness and use of screening mammography. Before the program, 12 percent of the Hispanic women surveyed in the intervention community had been screened, compared with 27 percent after the program. There was no change in screening among Hispanic women in the control community (23 percent before and 24 percent after the program). The program demonstrated that the awareness and behavior of "hard-to-reach" underscreened Hispanic women can be changed through intensive targeted outreach and that a church-based cancer control program can play an effective role in the process. This finding has national health policy implications.
