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. The balance of benefits versus harms of breast cancer screening is controversial. A Cochrane review stated that it is unclear if mammographic screening does more good or harm. Outcomes for breast cancer vary depending on the cancer type, the extent of disease , and the person's age.

Invasive Breast Cancer
Breast cancer is classified into different types based on how the cells look under a microscope. Most breast cancers are carcinomas, a type of cancer that begins in the linings of most organs. Ductal carcinoma in situ DCIS is characterized by cancerous cells that are confined to the lining of the milk ducts and have not spread through the duct walls into surrounding breast tissue. DCIS is the most common type of noninvasive breast cancer, with about 60, new cases diagnosed in the United States each year.
