Understanding Letrozole: Benefits and Side Effects

Letrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by decreasing the amount of estrogen produced in the body, slowing the growth of certain breast tumors that require estrogen to grow.
