Prostate Cancer Awareness Week was begun in 1989 to investigate whethe
r men could be recruited to participate in free prostate cancer screen
ing. Initially designed to raise public awareness of ''the ignored mal
e disease'', it has become the largest single cancer screening program
in the United States. In 1992, more than 500,000 men were examined by
digital rectal examination (DRE) and more than half of these also by
measuring prostate-specific antigen (PSA). Although the populations ex
amined have been generally better educated than the national average,
predominantly white, and typically (>40%) experiencing some symptom of
prostate disease, adherence to annual prostate examinations remains l
ow among successive cohorts of participants. Prostate cancers detected
through this program exhibit a more favorable stage distribution than
the national average. From 1989 through 1992, many cancers were detec
ted by using the effective combination of DRE and PSA testing, which r
esulted in more stage A disease being diagnosed and fewer stage B, C,
and D tumors. Data from 1992 suggest that increasing sophistication is
possible with PSA test results, and age-specific PSA reference ranges
have been developed.
