Abstract

Background: There is no decrease in the number of breast cancer deaths if screening mammography is performed
in women aged hereditary breast cancer. Therefore, more accurate screening mammography for young women is needed. Objective: To
evaluate the features of screening mammographic findings, particularly microcalcifications, in women aged to increase the positive predictive value of screening mammography in young women. Methods: We retrospectively
reviewed the data of consecutive women who underwent opportunistic and organized breast cancer screening at the
Sakuragaoka Hospital (Shizuoka, Japan) between April 2013 and March 2015. We compared the mammographic
findings and features of microcalcifications between women aged Results: The study included 3645 women. Of these 3645 women, 415 (11.4%) were aged were aged 40–49 years, and 2011 (55.2%) were aged 50–74 years. Women aged recalled for microcalcifications than those aged 50–74 years (Young women were more likely to be recalled for small round and segmental microcalcifications [(OR): 1.799 (95% CI: 0.751–2.846); 40–49 years, OR: 1.394 (95% CI: 0.714–2.074)] and less likely to be recalled for
small round and grouped microcalcifications [(95% CI: 0.496–1.428)] compared with women aged 50–74 years. Conclusions: On screening mammography, women
aged microcalcifications. False-positive results may be reduced by reflecting the characteristics of microcalcification findings
among young women without breast cancer in the future.
