Invasive carcinoma NST is a type of breast cancer. It is one of the invasive breast cancers that originates from the breast ductal system, so that it is a type of ductal carcinoma. A defining feature of this ductal carcinoma is that it lacks the "specific differentiating features" of other types of ductal carcinomas.
DCIS is a condition where the cells that line the milk ducts of the breast have become cancer, but they have not spread into surrounding breast tissue, per the American Cancer Society (ACS ...
Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. [ 1 ] [ 2 ] DCIS is classified as Stage 0. [ 3 ] It rarely produces symptoms or a breast lump that can be felt, typically being detected through screening mammography .
In recent years, many researchers have been focused on DCIS: ductal carcinoma in situ, the earliest stage of cancer that in most cases remains in the milk ducts and does not invade other tissues ...
Ductal carcinoma in situ, a condition sometimes called non-invasive or stage-zero breast cancer, is a very early finding of disease in the cells that line the milk ducts of the breast.

Comedocarcinoma is a kind of breast cancer that demonstrates comedonecrosis, which is the central necrosis [1] of cancer cells within involved ducts. Comedocarcinomas are usually non-infiltrating and intraductal tumors, characterized as a comedo-type, high-grade ductal carcinoma in situ (DCIS).
In fine-needle aspiration (FNA) smears, only 57% of cases show ductal carcinoma and metaplastic components. Consequently, roughly half of MBC tumors cannot be diagnosed by FNA. Pathologic tissue diagnosis is therefore essential to distinguish MBC from other breast cancers in order to institute proper and prompt treatment.
