About This Medication
What the Medication is Used For
AROMASIN is used for the adjuvant treatment of early breast cancer in postmenopausal women who had been treated previously with tamoxifen for 2 to 3 years.
AROMASIN is also used to treat advanced breast cancer in postmenopausal women who had been treated previously with antiestrogens (for example, tamoxifen).
Adjuvant means "in addition to". In early breast cancer, this means that additional treatment is required after primary treatment. The reason for this is that after surgery, a small number of cancer cells may remain in the body. These cells can continue to multiply and spread. Adjuvant therapy is given to prevent or delay these cells from multiplying and spreading. Cytotoxic chemotherapy, radiation, and hormonal treatment are three common forms of adjuvant treatment.
What it Does
AROMASIN interferes with a substance called aromatase which is needed to make the female sex hormone, estrogen, especially in postmenopausal women. AROMASIN reduces the amount of estrogen in the body. This is helpful because estrogen may influence the growth of certain types of breast cancer cells.
