Breast Cancer

Breast cancer is cancer that forms in 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.

HER-2 Positive Breast Cancer

Human epidermal growth factor receptor 2 (HER2) is a gene that can play an important role in the development of some types of breast cancer. This gene is also sometimes referred to as Erc-B2 receptor tyrosine kinase 2 (ERBB2). This gene is involved in the production of HER2 proteins, which are present on breast cells as receptors to control the growth, division, and repair of the cells.
