Stage zero breast cancer refers to DCIS otherwise known as Ductal Carcinoma In Situ. DCIS are abnormal cells that line the duct in a breast. A normal breast is made up of lots of ducts (these ducts carry milk to the nipple in a woman who is lactating).
DCIS is not an invasive cancer, meaning it hasn’t spread outside the milk duct and it cannot invade other parts of the breast. In some instances, if left untreated, doctors believe that DCIS can evolve into a more invasive breast cancer. For this reason, historically, the standard treatment for DCIS is to remove it surgically and in some instances offer radiation as well.
