Letrozole is a medication commonly used in the treatment of hormone receptor-positive breast cancer. It works as an aromatase inhibitor, reducing estrogen levels in the body, which can help slow the growth of certain types of breast tumors. Understanding the appropriate dosage of letrozole is crucial for maximizing its effectiveness while minimizing potential side effects.
