Although cancer-screening guidelines recommend periodic testing for women 50 years of age and older, these tests are underused. A search of databases identified 156 community-based breast, cervical, and colorectal cancer screening intervention studies published before April 2003. Most were conducted in the United States. More than half used randomization procedures or pre-post measures, and one third used both. Most reported significant intervention effects. Cervical and combined cervical and breast studies had higher rates of pre-post designs, and breast studies had the highest percentage using randomization. Although effective community-based breast and cervical interventions have been conducted, there is an urgent need for amplification of colorectal cancer screening.
