Tamoxifen is a pivotal medication in the management of hormone receptor-positive breast cancer, commonly prescribed to both women and men. This selective estrogen receptor modulator (SERM) works by blocking estrogen receptors in the breast tissue, thereby inhibiting the growth of cancer cells stimulated by estrogen. Understanding the appropriate dosage of Tamoxifen is crucial for maximizing its therapeutic benefits while minimizing potential side effects.
