Ductal carcinoma is a breast cancer that can be either invasive or in situ (inside).
Learn more about breast cancer from UPMC Hillman Cancer Center.
Ductal Carcinoma in situ (Stage 0) is the most common non-invasive breast cancer, where abnormal cells have been contained in the lining of the breast milk duct.
Invasive ductal carcinoma, the most common type of breast cancer, occurs when mutated cells spread from the milk ducts into the breast tissue. It can also metastasize and affect other parts of the body if left untreated.

Although anyone can develop this type of cancer, the following factors are known to increase your risk:
- Family history of breast cancer and ovarian cancer
