Ductal carcinoma in situ DCIS is a non-invasive cancer where abnormal cells have been found in the lining of the breast milk duct. The atypical cells have not spread outside of the ducts into the surrounding breast tissue.

Each breast contains 15 to 20 lobes of glandular tissue, arranged like the petals of a daisy. The lobes are further divided into smaller lobules that produce milk for breast-feeding. Small tubes ducts conduct the milk to a reservoir that lies just beneath your nipple. After skin cancer, breast cancer is the most common cancer diagnosed in women in the United States.
Breast cancer is cancer that develops from breast tissue. Risk factors for developing breast cancer include being female, obesity , lack of physical exercise, drinking alcohol , hormone replacement therapy during menopause , ionizing radiation , early age at first menstruation , having children late or not at all, older age, prior history of breast cancer, and family history.

Outcomes for breast cancer vary depending on the cancer type, the extent of disease , and the person's age.
