The Effects of Anastrozole: Understanding Its Role in Hormonal Therapy
Anastrozole is a medication primarily used in the treatment of breast cancer, particularly in postmenopausal women. As an aromatase inhibitor, it works by blocking the conversion of androgens into estrogen, thereby reducing estrogen levels in the body. This reduction is crucial since many breast cancers are fueled by estrogen. Understanding the effects of Anastrozole can help patients and healthcare providers make informed decisions regarding cancer treatment and management.

- Hot flashes
- Joint pain or stiffness
- Fatigue
- Nausea
It’s crucial for patients to discuss any side effects they experience with their healthcare provider to manage them effectively.
