Ductal Carcinoma in Situ (DCIS)

Ductal carcinoma in situ (DCIS) accounts for one out of every five new breast cancers. While nearly all DCIS is curable, there are many treatment options to consider. At the Abramson Cancer Center, we have the expertise to detect and diagnose small tumors in the earliest stages. Our specialized breast cancer team then works with you to create an individualized treatment plan.

What Is Ductal Carcinoma in Situ?

DCIS is cancer (abnormal cells) found in the milk ducts of the breast. Unlike other types of breast cancer, DCIS is noninvasive, meaning it has not spread to surrounding tissue or other parts of the body (metastatic breast cancer). DCIS is the earliest stage of breast cancer (stage 0).

DCIS is typically detected through breast cancer screening. While you may notice a lump or slight nipple discharge, DCIS rarely presents with the usual symptoms of breast cancer. DCIS may become invasive if left untreated, so early detection is critical.
