Treatment of Ductal Carcinoma In Situ (DCIS) of the Breast — First-Line Approach
Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer confined to the milk ducts. Selecting the appropriate primary local treatment is the central clinical decision, with multiple evidence-based surgical and radiation options available.
Treatment Overview
Primary local treatment involves surgical intervention — either breast-conserving surgery or, in selected cases, total mastectomy — each paired with specific radiation therapy considerations.
The complete protocol specifies which surgical approach applies, the role and sequencing of radiation, and the full set of decision criteria — access it below.
