Breast cancer, a.k.a. carcinoma of the breast, is a malignant form of cancer that develops in breast tissue, with the most common type starting at the lining of the ducts, i.e., ductal carcinoma.

The cause is still unknown for most types of breast cancer. Recent studies have identified genes BRC1 and BRC2 in a familial type of breast cancer. Other risk factors include age after 30, with the average age of women diagnosed being 60 years, and post-menopausal estrogen therapy and oral contraceptive use, although recent data could not confirm risk from estrogen replacement therapy.
