Intraductal carcinoma
A precancerous condition characterized by the clonal proliferation of malignant-looking
cells in the lining of a breast duct without evidence of spread outside the duct to other
tissues in the breast or outside the breast. DCIS is clearly the precursor (foreunner) of
invasive breast cancer. This is evident from the sharing of clonal chromosome changes by
DCIS and adjacent invasive cancers. In other words, invasive breast cancer evolves from
DCIS. Also called intraductal carcinoma.
