Features of Microcalcifications on Screening Mammography in Young Women

Abstract

Background: There is no decrease in the number of breast cancer deaths if screening mammography is performed<br />in women aged hereditary breast cancer. Therefore, more accurate screening mammography for young women is needed. Objective: To<br />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<br />reviewed the data of consecutive women who underwent opportunistic and organized breast cancer screening at the<br />Sakuragaoka Hospital (Shizuoka, Japan) between April 2013 and March 2015. We compared the mammographic<br />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<br />small round and grouped microcalcifications [(95% CI: 0.496–1.428)] compared with women aged 50–74 years. Conclusions: On screening mammography, women<br />aged microcalcifications. False-positive results may be reduced by reflecting the characteristics of microcalcification findings<br />among young women without breast cancer in the future.
