Understanding Letrozole: What Is It?
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 play a crucial role in reducing estrogen levels in the body. This decrease in estrogen can slow or stop the growth of certain types of breast tumors that require this hormone to grow.

The mechanism of action for letrozole involves inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens in postmenopausal women. By blocking this conversion, letrozole effectively lowers estrogen levels, thus depriving hormone-sensitive tumors of their primary growth stimulus.
