ductal carcinoma

Infiltrating duct carcinoma, infiltrating carcinoma–not otherwise specified Oncology The major pathologic form of breast CA, which accounts for 50-75% of all invasive breast CAs Pathology To be defined as DC, 90% of tissue examined must have a ductal pattern; grossly, DC is indurated with a stellate pattern of extension; DC imparts an unripe pear sensation when cut with a fresh scalpel. See Axillary dissection, Estrogen receptors. Cf Lobular carcinoma, Medullary carcinoma.
