Cancer screening in the United States, 2007: a review of current guidelines, practices, and prospects.

Each year, the American Cancer Society (ACS) publishes a summary of its recommendations for early cancer detection, including guideline updates, emerging issues that are relevant to screening for cancer, and a summary of the most current data on cancer screening rates for US adults. In 2006, there were no updates to ACS guidelines for early cancer detection. In this issue of the journal, we describe criteria for successful screening, discuss recent evidence and policy changes that have implications for cancer screening, summarize the ACS guidelines and describe guidelines reviews that are underway, and provide an update of the most recent data pertaining to participation rates in cancer screening from the Centers for Disease Control and Prevention's (CDC's) Behavioral Risk Factor Surveillance System (BRFSS) and the National Health Interview Survey (NHIS).
