Indicator Report - Breast Cancer - MammographyWhy Is This Important?Breast cancer is the most commonly occurring cancer in U.S. women (excluding basal and squamous cell skin cancers) and the leading cause of female cancer death in Utah. Deaths from breast cancer can be substantially reduced if the tumor is discovered at an early stage. Mammography is currently the best method for detecting cancer early. Clinical trials have demonstrated that routine screening with mammography can reduce breast cancer deaths by 20% to 30% in women aged 50 to 69 years (1-6), and by about 17% in women aged 40 to 49 years (7,8).There is consensus that women aged 40 or older should undergo routine screening with mammography at least every two years. The American Cancer Society recommends that women aged 40 or older have an annual mammogram, while the National Cancer Institute, the U.S. Preventive Services Task Force, and the U.S. Department of Health and Human Services recommend that women 40 years or older undergo mammography every one to two years (9, 10, 11). Women who are at higher than average risk of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and the frequency of that screening (10).

UT/US Old Methodology: Previous BRFSS methodology used "post-stratification" which was used to weight data by age, gender, and local health district (LHD). UT New Methodology: To reduce bias and more accurately represent population data, the BRFSS has changed survey methodology. It began conducting surveys by cellular phone in addition to landline phones. It also adopted "iterative proportional fitting" (raking) as its weighting method. With raking, education, race/ethnicity, marital status, home ownership/renter, and telephone source are included in the weighting procedure.Data SourcesUtah Data: Behavioral Risk Factor Surveillance System, Office of Public Health Assessment, Utah Department of Health.
