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 the growth of certain breast tumors that need estrogen to grow. Understanding its effects is crucial for patients and healthcare providers alike.

Key Effects of Letrozole
The effects of Letrozole can generally be categorized into therapeutic effects and side effects. Below are some significant points regarding each.
