Letrozole is a medication commonly used in the treatment of hormone receptor-positive breast cancer in women, particularly after surgery or radiation. It functions as an aromatase inhibitor, meaning it helps lower estrogen levels in the body. Understanding the appropriate letrozole dosage is crucial for maximizing its effectiveness while minimizing potential side effects.
