Letrozole is a medication primarily used for the treatment of hormonally-responsive breast cancer after surgery. It belongs to a class of drugs known as aromatase inhibitors, which work by lowering estrogen levels in the body. This reduction in estrogen can have several effects, both beneficial and side effects, especially in specific populations such as athletes and bodybuilders.
