Letrozole is a well-established medication primarily used in the treatment of hormonally-responsive breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which play a critical role in managing hormone-sensitive tumors in women, particularly postmenopausal women. The main mechanism of action involves inhibiting the aromatase enzyme, leading to reduced estrogen levels in the body. This is especially crucial since many breast cancers depend on estrogen for growth and proliferation.
Letrozole is commonly used as an aromatase inhibitor in the treatment of hormonally-responsive breast cancer. It works by decreasing the amount of estrogen produced in the body, which can slow or reverse the growth of breast tumors.

Indications for Letrozole Use
- Adjuvant Treatment of Early Breast Cancer: Letrozole is frequently prescribed as an adjuvant therapy following surgery to reduce the risk of cancer recurrence in women with estrogen receptor-positive (ER-positive) early breast cancer.
- Advanced Breast Cancer: It is also indicated for the treatment of postmenopausal women with ER-positive breast cancer that has progressed after tamoxifen therapy.
- Neoadjuvant Therapy: In some cases, Letrozole may be used as a neoadjuvant treatment to shrink tumors before surgical intervention, thereby increasing the chances of successful surgery.
- Prevention of Breast Cancer: While not a first-line use, Letrozole may be considered in women at high risk of developing breast cancer due to genetic predisposition or family history, to lower the risk of onset.
Overall, Letrozole plays a pivotal role in the management of hormone-sensitive breast cancers, and ongoing research continues to explore its efficacy in various cancer treatment regimens.
