Understanding the Letrozole Course: Benefits, Usage, and Considerations
Letrozole is a medication commonly used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing the levels of estrogen in the body, thereby slowing or stopping the growth of certain types of breast tumors that require estrogen to grow.

Possible Side Effects
Patients using Letrozole may experience some side effects, including:
- Hot flashes.
- Nausea.
- Fatigue.
- Joint pain.
- Bone density loss.
Conclusion
Letrozole is a vital drug in the management of hormone receptor-positive breast cancer, offering women an effective option for treatment.
