Understanding Letrozole Dosage: A Comprehensive Guide
Letrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It is an aromatase inhibitor that works by reducing estrogen levels in the body, thereby slowing the growth of certain types of breast tumors that require estrogen to grow. Understanding the correct dosage of Letrozole is crucial for effective treatment and minimizing potential side effects.
