About 60,000 people are diagnosed with ductal carcinoma in situ (DCIS) each year—accounting for one out of every five new breast cancers. While nearly all DCIS is curable, treatment plays an important role in preventing breast cancer recurrence (coming back). 

At Penn Medicine Lancaster General Health, we understand the importance of finding breast cancer early. We have the experience and expertise to detect small tumors in the earliest stages. Our specialized breast cancer team works with you to personalize your care and offer the most effective treatment.

What Is Ductal Carcinoma in Situ?

DCIS is cancer found in the milk ducts of the breast. It is the only noninvasive type of breast cancer, 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).

Detecting Stage 0 Breast Cancer

DCIS is typically detected through breast cancer screening. The number of people diagnosed with DCIS has increased as more women get yearly mammograms.

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 finding it early is important.
