Abstract
Introduction: Routine mammography screening with clinical breast examination is effective
in reducing breast cancer mortality. The Breast and Cervical Health Program (BCHP)
in Washington State provides free breast and cervical cancer screening for low-income
women, with an emphasis on women of color. This study examined initial breast cancer
rescreening and factors associated with rescreening for women enrolled in BCHP in
King County, Washington.
Methods: Data were obtained from the Washington State BCHP tracking system. We estimated
the percentages who received breast cancer rescreening for women enrolled between
July 1994 and December 1995 using survival analysis. Cox proportional regression was
also used to examine factors associated with time-until-rescreening.
Results: Survival analysis showed that the overall percentages rescreened at 15 and
27 months for women aged 50–69 were 25.7% and 45.0%, respectively. For women aged
40–49, the corresponding percentages were 26.0% and 40.3%. Rescreening differed by
age groups, race/ethnicity, level of education, foreign born status, history of previous
mammography, and enrollment clinic.
Conclusions: Results from this study suggested that in addition to initial efforts
for enrollment, screening programs should emphasize increased rescreening especially
for women with certain demographic and screening history characteristics.
