Since its approval intamoxifen has been used to treat millions of women and men diagnosed with hormone-receptor-positive breast cancer. While an aromatase inhibitor is the first hormonal therapy medicine choice for postmenopausal women, tamoxifen is the first choice for premenopausal women and is still a good choice for postmenopausal women who can't take.
