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).
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 .

Pre-cancer of the breast is a precancerous condition of the breast. It may eventually develop into breast cancer. There are two types: Ductal carcinoma in situ, the most common type of breast pre-cancer; Lobular carcinoma in situ, pre-cancer of the breast that is outside the milk ducts
Scientists study the behaviour of isolated cells grown in the laboratory for insights into how cells function in the body in health and disease. Experiments using cell culture are used for developing new diagnostic tests and new treatments for diseases. This is a list of major breast cancer cell lines that are primarily used in breast cancer ...
Lobular neoplasia is considered pre-cancerous, and LCIS is an indicator (marker) for increased risk of developing invasive breast cancer in women. This risk extends more than 20 years. Most of the risk relates to subsequent invasive ductal carcinoma rather than to invasive lobular carcinoma. [4]
The appearance of cancer cells under a microscope is another predictor of systemic spread. The more different the cancer cells look compared to normal duct cells, the greater the risk of systemic spread. There are three characteristics that differentiate cancer cells from normal cells. Tendency to form tubular structures
Carcinoma in situ (CIS) is a group of abnormal cells. [ 1 ] [ 2 ] While they are a form of neoplasm , [ 3 ] there is disagreement over whether CIS should be classified as cancer . This controversy also depends on the exact CIS in question (e.g., cervical, skin, breast).
