Breast cancer is the third leading cause of death from cancer among females in Macao, but little is known about local practice of breast cancer screening. The study aims to evaluate breast cancer screening behaviors and to identify the predictors of insufficient knowledge and attitudes towards breast cancer and its screening among female residents.
This was a cross-sectional study conducted from April to June 2016 in Macao. Quota sampling of women completed the modified Chinese Breast Cancer Screening Beliefs questionnaire (CBCSB) to assess their breast cancer-related perceptions, screening attitudes and behaviors. Univariate and multivariate logistic regressions were performed to identify the predictors of poor-screening practices, attitudes, knowledge and perceived barriers to mammography.
A total of 417 women (mean age±SD: 50.5±5.7) completed surveys, with 160 (38.4%), 196 (47.0%) and 103 (24.7%) women received breast self-examination, clinical breast examination and mammography as recommended, respectively. Nulliparity (OR=2.56, 95% CI = 1.14−5.73) and low education (OR = 1.72, 95% CI = 1.04−2.84) were significantly associated with negative attitude towards health check-ups. Women did not know anyone with breast cancer (OR = 2.30, 95% CI = 1.50−3.55) were more likely to have insufficient knowledge about breast cancer. Low education (OR = 1.95, 95% CI = 1.25−3.04) and not knowing anyone with breast cancer (OR = 2.02, 95% CI = 1.31−3.13) were identified as predictors for perceived barriers to mammography.
Recommendations for breast cancer screening are poorly followed by the residents in Macao, and a culturally tailored educational program is urgently needed to raise the public’s awareness of the disease and the screening practices.
