Letrozole is a medication commonly used in the treatment of hormone receptor-positive breast cancer, particularly in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by lowering estrogen levels in the body. By reducing estrogen, letrozole can slow or stop the growth of certain types of breast tumors that require estrogen to grow.

- Side Effects: As with any medication, letrozole has side effects. Common side effects include hot flashes, joint pain, fatigue, and nausea.
- Bone Health: Letrozole can impact bone density, leading to an increased risk of osteoporosis and fractures.
- Impact on Menstrual Cycle: In premenopausal women, letrozole can disrupt the menstrual cycle. However, it is typically used in postmenopausal women.
Patients should have a thorough discussion with their healthcare provider regarding the potential effects of letrozole to ensure they are well-informed and monitored throughout their treatment journey.
