Dcis is considered the earliest form of breast cancer. Ductal carcinoma in situ dcis means the cells that line the milk ducts of the breast have become cancer but they have not spread into surrounding breast tissue. Dcis is noninvasive meaning it hasn t spread out of the milk duct and has a low risk of becoming invasive. The type of tissue where your breast cancer arises determines how the cancer behaves and what treatments are most effective.

In dcis the abnormal cells are contained in the milk ducts canals that carry milk from the lobules to the nipple openings during breastfeeding. It s called in situ which means in place because the cells have not left the milk ducts to invade nearby breast tissue. In stage 0 breast cancer the atypical cells have not spread outside of the ducts or lobules into the surrounding breast tissue. There are two types.

Stage 0 breast cancer ductal carcinoma in situ dcis is a non invasive cancer where abnormal cells have been found in the lining of the breast milk duct.
