About Breast Cancer

Making the right diagnosis is a critical component of successful cancer treatment. Penn's cancer specialists have wide-ranging experience treating all forms of breast cancer, including those that occur only rarely. Their expert understanding of the disease allows them to create cancer treatment plans that are customized for every patient.

Breast cancer, the uncontrolled growth of cells in the breast, is the most common type of cancer among women, excluding skin cancer. Breast cancer forms in the tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.
