What is Ductal Carcinoma In Situ (DCIS)?

Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer originating from the epithelial cells lining the breast ducts that has not crossed the basement membrane. It accounts for about 20% of breast cancers.

Diagnostic frequency has increased with the spread of mammography screening. It is mostly asymptomatic and is detected through microcalcifications. Comedo, cribriform, micropapillary, and solid histological patterns have been described.

If untreated, it may progress to invasive ductal carcinoma in 20-30% of cases. Treatment is individualized according to lesion size, grade, hormone receptor status, and patient preference. Breast-conserving surgery plus radiotherapy or mastectomy are standard approaches.
