Tamoxifen is an anti-hormone medication that works by blocking the action of estrogen. It does not replace a hormone in the body, nor does it directly cause the breast tumour to shrink. However, by blocking estrogen, tamoxifen can slow or stop the growth of breast cancer cells. It does not cause the cancer to become more aggressive.
