Ductal carcinoma in situ. Malignant epithelial proliferation occupying duct spaces but confined within the basement membrane. It is a heterogeneous entity, radiologically, pathologically and biologically.
DCIS stands for ductal carcinoma in situ. DCIS is an early form of breast cancer that starts in the milk ducts. See breast cancer section.
Abnormal cells that involve only the lining of a duct and have not spread outside the duct to other tissues in the breast. Also called DCIS or intraductal carcinoma.
Ductal carcinoma in situ. Ductal cancer cells that have not grown outside of their site of origin, sometimes referred to as precancer
Ductal Carcinoma In Situ. DCIS is a non-invasive breast cancer. Cancer cells fill the ducts but do not spread through the walls of the ducts into the fatty tissue of the breast. Nearly 100% of women diagnosed at this early stage of breast cancer may be cured. Only in the rarest circumstances can breast self-examination or clinical breast examination detect DCIS. The changes can be seen by means of a screening mammography. With more women getting mammograms each year, the diagnosis of DCIS is becoming more common.
Ductal carcinoma in situ. Ductal carcinoma in situ is the most common type of noninvasive breast cancer. There are cancer cells inside the ducts but they have not spread through the walls of the ducts into the fatty tissue of the breast nor spread to other organs in the body. More information on types of breast can be found at the American Cancer Society’s Breast Cancer Resource Center at http://www3.cancer.org/cancerinfo/load_cont.asp?ct=5&st=wi
Sometimes DCIS may be described as pre-cancerous, pre-invasive, non-invasive or intraductal cancer. This is when cancerous changes occur in the cells lining the milk ducts (the channels in the breast that carry milk to the nipple), but the breast cancer cells are completely contained within the ducts and have not spread into the surrounding breast tissue. The DCIS usually shows up on a mammogram as an area where calcium has been deposited in the ducts (microcalcification). It is important to know that most microcalcification is not DCIS or cancer. http://www.cancerbacup.org.uk/info/dcis.htm
Ductal Carcinoma In Situ. Type of early breast cancer affecting the ducts of the breast. Means the cancer cells are all inside the Ducts (passageways) of the breast and have not broken out. This is important as it means the chance of the cancer cells having spread anywhere else in the body is very low indeed.
Ductal carcinoma in situ. see ‘Carcinoma in situ'.
ductal carcinoma in situ. Cancer cells that develop from the lining of the milk duct but are confined to the ducts of the breast. DCIS is considered to be a precursor to invasive cancer.
Ductal carcinoma in situ. A noninvasive, precancerous condition in which abnormal cells are found in the lining of a breast duct. The abnormal cells have not spread outside the duct to other tissues in the breast. In some cases, DCIS may become invasive cancer and spread to other tissues, although it is not known at this time how to predict which lesions will become invasive. Also called intraductal carcinoma.

A collection of abnormal cells which are found only in the lining of the milk duct of the breast. These abnormal cells have not spread outside of the duct. This early noninvasive form of cancer is usually curable.
Ductal carcinoma in situ. a precancerous lesion that appears in the ducts of the breast. This type of lesion may eventually convert into an invasive breast cancer.
Ductal Carcinoma in Situ. Abnormal cells that involve only the lining of a duct in the breast. The cells have not spread outside the duct to other tissues in the breast. Also called intraductal carcinoma.
Ductal carcinoma in situ. Cancer cells that start in the milk passages (ducts) but have not penetrated the duct walls into the surrounding tissue. This is a highly curable form of breast cancer that is treated with surgery or surgery plus radiation therapy.

Ductal Carcinoma In Situ. The most common form of treatable breast cancer, when found early. It spreads along the ducts of the breast, rather than forming a lump.
Ductal carcinoma in situ. Cancer that is confined to the ducts of the breast tissue.
Ductal carcinoma in situ. 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 (forerunner) 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. See the entire definition of DCIS
cancer that remains within the walls of the duct.
