Letrozole: What Is It?
Letrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. As an aromatase inhibitor, it works by reducing estrogen levels in the body, which can slow or stop the growth of certain types of breast tumors that require estrogen to grow.
How Does Letrozole Work?
Letrozole acts by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens in peripheral tissues. By blocking this process, letrozole effectively decreases the overall estrogen production, creating an unfavorable environment for estrogen-dependent tumors.
Benefits of Letrozole
- Effective Treatment: Studies have shown that letrozole can significantly improve disease-free survival rates in women with early-stage breast cancer.
- Adjuvant Therapy: It is often used as an adjuvant therapy after surgery to reduce the risk of cancer recurrence.
- Metastatic Breast Cancer: Letrozole is also prescribed for advanced or metastatic breast cancer, helping to manage symptoms and prolong life.
Common Side Effects

Who Should Avoid Letrozole?
Letrozole should not be taken by individuals who are:
- Pregnant or breastfeeding
- Allergic to letrozole or any of its components
- Postmenopausal women with hormone receptor-negative breast cancer
Conclusion
In summary, letrozole is a critical medication in the fight against specific types of breast cancer. Its mechanism of action, benefits, and common side effects make it a vital topic for those considering treatment options.
