ASO Author Reflections: The Association Between Low-Risk DCIS and Screening Ultrasound over the Past 10 Years

Abstract

The proportion of ductal carcinoma in situ (DCIS) among breast cancers has increased from 3% to 25% on the strength of population-based mammography. On the other hand, as patients diagnosed with DCIS generally show excellent long-term survival, nowadays low-risk DCIS is under investigation for the possibility of active surveillance rather than surgical treatment in three ongoing trials. Considering these changes, it is meaningful to know the chronological trend of DCIS from clinical, pathological, and radiological perspectives.
