Several of my dear friends do have actual breast cancer and are undergoing necessary treatment. The below refers to DCIS grade level 0.

Definitions by the National Cancer Institute. Notice that THEY do NOT call DCIS "cancer cells" or "cancerous cells" or "precancer/ous" - they call them "abnormal cells." http://www.cancer.gov/Templates/db_alpha.aspx?CdrID=44394 [Warts, skin tags etc. are "abnormal cells" too, though some doctors also call them "precancerous" - as shown in below articles - ]
A term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.
A form of cancer that begins in melanocytes (cells that make the pigment melanin). It may begin in a mole (skin melanoma), but can also begin in other pigmented tissues, such as in the eye or in the intestines.
melanocyte (mel-AN-o-site) A cell in the skin and eyes that produces and contains the pigment called melanin.
melanoma in situ (MEH-luh-NOH-muh in SY-too)
Abnormal melanocytes (cells that make melanin, the pigment that gives skin its color) are found in the epidermis (outer layer of the skin). These abnormal melanocytes "may" become cancer and spread into nearby normal tissue. Also called stage 0 melanoma.
A noninvasive 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 ductal carcinoma in situ and intraductal carcinoma.

http://www.wisegeek.com/what-is-the-difference-between-benign-precancerous-and-malignant.htm (notice the sentence: Certain growths or tumors have the potential to become malignant, but their cell growth has not yet become uncontrolled. A number of skin tags and moles fall under this description of precancerous.)
http://www.medpagetoday.com/HematologyOncology/BreastCancer/1004 - a deceptive article but do notice the paragraphs:
The prolonged follow-up time required to detect all of these invasive breast cancers -- up to 42 years -- and the pattern of subsequent invasive cancers indicates that low-grade DCIS is a distinct pathology from both high-grade DCIS and atypical hyperplasia. The results further emphasize the need to treat these pathologies as different entities.
The slow progression to invasive breast cancer in the women enrolled in the current study means that "women can have stable carcinoma for decades," wrote the Vanderbilt team. Therefore, the disease course for low-grade DCIS differs dramatically from that of high-grade DCIS, which is known to lead to invasive cancers more quickly.

In numerous recent studies, regardless of treatment, the long-term survival rate for women with DCIS is nearly 100%.
