Use of skin and oral cancer examinations in the United States, 1998.
BACKGROUND
Findings from previous surveys suggest low utilization of oral cancer examinations, even though this examination is noninvasive. The purpose of this analysis is to compare the use of an oral cancer examination (OCE) and a skin cancer examination (SCE) in the past 12 months within the United States. Both exams are noninvasive and include a visual component.


METHODS
Weighted data from the Adult Prevention Supplement of the 1998 National Health Interview Survey (NHIS) for adults 40 years of age or older were analyzed using SAS and SUDAAN. A ratio compared the percentage reporting an OCE (%OCE) with the percentage reporting a SCE (%SCE).


RESULTS
The percentage having an OCE in the past year (13.8%) was very similar to the percentage having a SCE (13.5%) during that same period. With increasing age group, the %OCE/%SCE ratio varied inversely from 1.60 (C.I. 1.42-1.78) among persons 40-49 years to 0.62 (C.I. 0.55-0.69) among persons 70+ years. The ratio was similar in whites and blacks, males and females, and Hispanics and non-Hispanics. There was a positive gradient in the ratio by education and family income.


CONCLUSIONS
Overall, less than 15% of the population is receiving either of these examinations, although the American Cancer Society recommends both of them on an annual basis for individuals 40 years of age and older. To increase detection of these cancers at early stages, extensive educational and media campaigns for the public and providers identifying risk factors and the availability of and the need for these examinations are required.
