In some cases, DCIS may become invasive and spread to other tissues, but there is no way of determining which lesions will remain stable without treatment, and which will go on to become invasive. It is also called pre-invasive, non-invasive, or intraductal cancer.

Un nuevo estudio sugiere que las mujeres diagnosticadas con células anormales en el revestimiento de un conducto de seno, —afección no invasora llamada carcinoma ductal in situ, o CDIS, — tienen en general un riesgo bajo de morir por cáncer de seno.Además, el tratamiento de estas lesiones puede ayudar a evitar una recurrencia en el seno pero no parece que haga disminuir el riesgo ya .

[13] Research shows that survival is the same with lumpectomy as it is with mastectomy, whether or not a woman has radiation after lumpectomy. [4][5] It has been diagnosed in a significant percentage of men (see male breast cancer). Tumours that do not make ER or PR are described as hormone negative. Carcinoma in situ, or stage 0 cancer, refers to precancerous cells in a limited area. In situ means "in place" and refers to the fact that the abnormal cells have not moved out of the mammary duct and into any of the surrounding tissues in the breast ("pre-cancerous" refers to the fact that it has not yet become an invasive cancer). With lumpectomy, the surgeon only removes the abnormal tissue in the breast. Effect of tamoxifen and radiotherapy in women with locally excised ductal carcinoma in situ: long-term results from the UK/ANZ DCIS trial. At this stage, the cells have not broken through the walls of the milk ducts into the surrounding breast tissue. Once the carcinoma cells have grown and broken out of the ducts or lobules, it is called invasive or infiltrating carcinoma. There are three types of lymph nodes that may be described in your report: If cancer cells are found in a lymph node, the size of the area involved by cancer will be measured and described in your report as follows: Finding cancer cells in a lymph node is associated with an increased risk that cancer will come back at a distant body site such as the lungs in the future.

In DCIS, abnormal cells are found in the lining of one or more milk ducts in the breast. There are 2 main types of in-situ carcinoma of the breast: ductal carcinoma in-situ (DCIS) and lobular carcinoma in situ (LCIS). DCIS is also called intraductal carcinoma or stage 0 breast cancer.

The milk ducts are the canals that carry milk from the lobules to the nipple openings during breastfeeding. The place where DCIS starts is the terminal duct lobular unit. In order to make the diagnosis of DCIS, all of the tumour cells must be located inside the ducts. Local excision alone without irradiation for ductal carcinoma in situ of the breast: a trial of the Eastern Cooperative Oncology Group. According to Dr. Polyak, “Even though DCIS by itself is not a life-threatening disease, understanding why some patients with DCIS develop invasive breast cancer while others do not would help our understanding of drivers of tumor progression and the design of more effective therapies.”.
