Letrozole is a medication commonly used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It works by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens, thereby reducing estrogen levels in the body. This reduction is critical, as some breast cancers require estrogen to grow. Understanding the Letrozole course is essential for patients and athletes looking to optimize their performance while being aware of its implications.

Considerations When Taking Letrozole
- Side Effects: Common side effects include hot flashes, joint pain, and fatigue. It’s important to monitor any adverse reactions.
