Understanding Letrozole
Letrozole is a medication primarily used in the treatment of certain types of breast cancer, particularly hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by decreasing estrogen levels in the body.

Letrozole is an oral medication that effectively lowers estrogen production by inhibiting the aromatase enzyme. This is crucial because some breast cancers grow in response to estrogen. By reducing estrogen levels, letrozole helps to slow or stop the growth of these cancer cells.
