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.
But women and men! Here are 20 things you should know about this common yet often misunderstood breast disease. Each breast has about 15 to 20 milk ducts, which, in women, act as a canal system to transport milk to nursing babies.
Ductal carcinoma in situ DCIS is non-invasive breast cancer. Ductal means that the cancer starts inside the milk ducts, carcinoma refers to any cancer that begins in the skin or other tissues including breast tissue that cover or line the internal organs, and in situ means "in its original place. When you have had DCIS, you are at higher risk for the cancer coming back or for developing a new breast cancer than a person who has never had breast cancer before.
Chemotherapy, a form of treatment that sends anti-cancer medications throughout the body, is generally not needed for DCIS. DCIS is non-invasive and remains within the breast duct, so there is no need to treat cancer cells that might have traveled to other areas of the body. Each individual situation is different.
Ductal carcinoma in situ DCIS is a type of breast cancer. This is also called non-invasive or pre-invasive breast cancer. The cancer cells are found along the sides of the milk duct within the breast.
Despite the fact that its name includes the term "carcinoma," LCIS is not a true breast cancer. Rather, LCIS is an indication that a person is at higher-than-average risk for getting breast cancer at some point in the future. LCIS is restricted to the lobules.
Ductal carcinoma in situ DCIS means the cells that line the milk ducts of the breast have become cancerbut 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.

Scott Steele : So for those listeners out there, we've had your husband Michael Valente who's in my department.
Biopsies are done only to make the diagnosis. If DCIS is diagnosed, more surgery is needed to ensure all of the cancer is removed along with "clear margins," which means that a border of healthy tissue around the cancer is also removed. Usually this means having lumpectomy, or in some cases a large area of DCIS, for examplemastectomy.
If you have DCIS, you have abnormal cells in your milk ducts which have not spread into your breast tissue. You may need treatment, but you do not have invasive breast cancer. As a result, most women with DCIS do not show any signs or symptoms of having breast cancer. Mammograms and ultrasounds are the most common ways in which DCIS is diagnosed.
