Ductal carcinoma in situ (DCIS) is an abnormal proliferation of cells in the mammary ducts.
While cells display abnormal cytological features similar to those of invasive breast cancer, unlike invasive breast cancer, DCIS is confined within the duct system. If left untreated, DCIS may increase the risk of developing invasive breast cancer later in life.
