Treatments for metastatic breast cancer aim to alleviate symptoms and improve survival. Chemotherapy will be used in most women with advanced disease, either as a single agent or as a combination of two or more anti-cancer agents.
Combination chemotherapy typically provides a survival benefit over monotherapy, but this may be at the cost of increased side effects. Hormone treatments are typically better tolerated than cytotoxic agents.
Breast cancer is also described according to whether or not the tumor over-expresses progesterone receptors or the human epidermal growth factor receptor 2 (HER2) oncogene. HER2 status is used as a prognostic indicator and is a key determinant of systemic treatment selection.
