What is Tamoxifen?

Tamoxifen is a medication classified as a Selective Estrogen Receptor Modulator (SERM). It is primarily used in the treatment and prevention of estrogen receptor-positive breast cancer by blocking estrogen's effects in breast tissue.

Key Potential Benefits & Uses

Based on research and clinical use, Tamoxifen is often used for:

  • Breast Cancer Treatment: Treating hormone receptor-positive breast cancer in women and men, both early and advanced stages.
  • Breast Cancer Prevention: Reducing the risk of developing invasive breast cancer in women at high risk.
  • Gynecomastia Treatment (Off-label): Occasionally used off-label to treat or prevent gynecomastia (enlargement of male breast tissue).
  • Mechanism: Works by binding to estrogen receptors, acting as an antagonist (blocker) in some tissues (like breast) and an agonist (activator) in others (like bone and uterine lining).

Scientific Evidence: What Does the Research Say?

  • Extensive Clinical Evidence: Numerous large-scale clinical trials have demonstrated Tamoxifen's effectiveness in reducing recurrence and mortality in estrogen receptor-positive breast cancer patients, and in preventing breast cancer in high-risk individuals.
