How Letrozole Works

- Aromatase Inhibition: Letrozole inhibits the aromatase enzyme, which is responsible for converting androgens into estrogens in postmenopausal women.
- Estrogen Level Reduction: By decreasing estrogen production, Letrozole lowers the amount of this hormone available to stimulate the growth of certain types of breast tumors.
- Slowing Tumor Growth: Reduced estrogen levels lead to decreased tumor cell proliferation, contributing to slower cancer progression and improving patient outcomes.
