Letrozole is an aromatase inhibitor primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It works by decreasing the amount of estrogen the body makes, which can slow or stop the growth of certain types of breast tumors that require estrogen to grow. This makes it a crucial component in the management of breast cancer treatments.

How Letrozole Works
Letrozole functions by inhibiting the aromatase enzyme, which is responsible for converting androgens to estrogens. In postmenopausal women, most estrogen is made through this process. By reducing estrogen levels, Letrozole can help prevent cancer cell growth.

Letrozole is indicated for:
- Treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women.
- Adjuvant treatment of early hormone receptor-positive breast cancer following surgery.

Dosage and Administration
Letrozole is usually taken orally once a day. The typical dosage for breast cancer treatment is 2.5 mg per day. It can be taken with or without food. Patients are advised to follow their healthcare provider’s instructions precisely for optimal results.
Side Effects

- Hot flashes
- Joint pain or stiffness

Patients should report any severe side effects or unusual symptoms to their healthcare provider promptly.
Conclusion
Letrozole plays a significant role in modern breast cancer therapy, improving outcomes for many patients. Understanding its mechanism, usage, and potential side effects is essential for anyone considering this treatment option. Consultation with a healthcare provider is vital for personalized medical advice.
