BackgroundIn recently updated breast cancer screening guidelines, the American Cancer Society (ACS) and United States Preventive Services Task Force (USPSTF) recommended increasing mammography screening intervals for various age groups. In addition, ACS does not recommend clinical breast examination (CBE) for routine screening among average-risk women. Our study explores women's attitudes regarding screening mammography and CBE and evaluates the impact of the updated USPSTF and ACS guidelines on these attitudes.Materials And MethodsSix hundred fourteen patients presenting to Mayo Clinic, Arizona and Minnesota, in July 2016 completed a self-administered survey, which included a summary of the updated guidelines.ResultsA majority of the 555 women who fit the inclusion criteria reported that CBE and mammogram are useful in detecting breast cancer and should be performed annually, and 51% of participants were unaware of the updated guidelines. Before reviewing the guidelines, 77% believed yearly CBE and 76% believed yearly mammogram was needed for routine screening. After reviewing the guidelines, the percentage of women who planned to continue with yearly CBE and mammogram decreased significantly to 61% and 64%, respectively (p < 0.001 and p < 0.001). Nearly half the participants (48%) believed the most influential reason for the guideline change was to decrease healthcare spending.ConclusionBreast cancer screening is well received among patients, and a majority of surveyed women were unaware of recent guideline changes. After reviewing the guidelines, there was a significant downward shift in intended screening frequency, although the majority still planned to undergo annual screening. Informing women about updated evidence-based guidelines may influence their knowledge, preferences, and opinions.
