Approximately 10% of screening mammograms result in a recall for additional imaging, although <2% result in a Female Breast Cancer Screening For women 40 to 49 years of age, randomized controlled trials and observational studies demonstrate that screening mammography decreases breast cancer mortality by 15% to 50% [1,8,32,33,39]. Results from the Cancer Intervention and Surveillance Modeling Network (CISNET) suggest that annual screening mammography in women 40 to 49 years of age saves 42% more lives and life-years than biennial screening due to faster growing tumors in younger women [31]. Women screened between 40 and 49 years of age are also less likely to require mastectomy or chemotherapy than women diagnosed with palpable tumors [2]. Non-Hispanic Black, Hispanic Black, and Hispanic White women have higher breast cancer mortality than non- Hispanic White women, and minority women often present at younger ages with more aggressive tumor subtypes [3,8]. Therefore, decreasing access to screening mammography, especially in women 40 to 49 years of age, may disproportionately impact minority women. Annual screening mammography results in a greater reduction in mortality compared to biennial screening [8]. In women 40 to 84 years of age, annual screening reduces mortality by 40%, compared to a 32% reduction for biennial screening [32]. With regular screening, interval breast cancers do occur with a higher frequency in women undergoing biennial or triennial screening compared to annual screening. The sensitivity of mammography is decreased in some groups of women, including those with dense breasts [40]. Dense breast tissue decreases the sensitivity of mammography [26] and is an independent risk factor for developing breast cancer [27].
