What is tamoxifen?

Tamoxifen is the most commonly prescribed hormonal treatment. It is prescribed for newly diagnosed women, patients with metastatic disease and sometimes, for women at high risk for contracting breast cancer. The usual dosage is 20 mg per day for five years taken in pill form once or twice daily. Tamoxifen blocks the effects of estrogen on breast tissue without changing your body's production of estrogen.
