Many studies have demonstrated the utility of tamoxifen for the treatment of estrogen receptor (ER)-positive breast cancer (1) and more recently for the prevention of breast cancer in women at increased risk (24). However, the toxicities of tamoxifen such as thromboembolic events and endometrial cancers still pose a clinically significant problem. To reduce the risk of these adverse events, effective, yet safe drugs are being sought that could replace tamoxifen. Indeed, new endocrine agents such as selective ER modulators (SERMs) and aromatase inhibitors are being evaluated as alternatives to tamoxifen for the treatment (59) and prevention (10) of breast cancer. In this issue of the Journal, Decensi et al. (11) propose a different strategy to reduce the side effects of tamoxifen. They suggest that, by using a lower dose
