Trends in cancer screening--United States, 1987 and 1992.

Screening methods and programs are critical strategies for the early detection and timely treatment of some cancers. Established methods for early detection of cancer include mammography, clinical breast examination (CBE), the Papanicolaou (Pap) test, proctosigmoidoscopy, fecal occult blood test (FOBT), and digital rectal examination (DRE) (1-4). To examine changes in the reported use of selected cancer screening tests, the National Cancer Institute analyzed data from CDC's National Health Interview Survey (NHIS) for 1987 and 1992 to calculate rates of use and compared these rates with the national health objectives for the year 2000 (5). This analysis suggests that, although the use of these tests increased, substantial progress is needed to meet the objectives.
