Mammographic and breast tomosynthesis findings in patients following breast conservative therapy

Abstract

Breast conservative therapy (BCT) involves removal of tumor along with tumor-free margin followed by radiotherapy. Owing to improvement in imaging methods, patient awareness, and screening programs, more and more patients are becoming eligible for BCT; however, this procedure results in various changes in breast parenchyma, whose mammographic appearances may be confused with residual or recurrent lesion. Therefore, awareness of expected and unexpected mammographic findings following BCT is essential for optimal evaluation of these patients. This pictorial essay intends to demonstrate digital mammographic findings in post BCT patients with emphasis on differentiation between expected and unexpected findings.
