Letrozole is a medication primarily used for the treatment of hormone receptor-positive breast cancer in postmenopausal women. It functions as an aromatase inhibitor, effectively reducing the levels of estrogen in the body, which can promote the growth of certain types of breast tumors. Due to its specific action, Letrozole has become an important tool in oncological treatments, but it is crucial to understand its effects, both beneficial and adverse.
