The American Cancer Society estimates that more than 62, news cases of carcinoma in situ will be diagnosed this year. A common type of carcinoma in situ called DCIS ductal carcinoma in situ or intraductal carcinoma. Ductal carcinoma in situ or DCIS refers to the most common type of noninvasive breast cancer in women. In situ , or "in place," describes a cancer that has not moved out of the area of the body where it originally developed. With DCIS, the cancer cells are confined to milk ducts in the breast and have not spread into the fatty breast tissue or to any other part of the body such as the lymph nodes.

Ductal carcinoma in situ DCIS means the cells that line the milk ducts of the breast have become cancer, but they have not spread into surrounding breast tissue. DCIS is considered non-invasive or pre-invasive breast cancer. But sometimes a mastectomy might be a better option. In breast-conserving surgery BCS , the surgeon removes the tumor and a small amount of normal breast tissue around it.
Ductal carcinoma in situ (DCIS)
By Jim Stallard Monday, October 21, MSK surgeon Melissa Pilewskie says that even though DCIS is noninvasive and not life-threatening, surgery is nearly always recommended to treat the disease. But patients are often confused about DCIS, what it means, and what to do about it. This is actually a controversial topic, partly due to the language. DCIS refers to abnormal cells that are confined to the milk ducts.
DCIS means that some cells in the lining of the ducts of the breast tissue have started to turn into cancer cells. These cells are all contained inside the ducts. They have not started to spread into the surrounding breast tissue.
