Letrozole is an aromatase inhibitor. It works by decreasing the amount of estrogen (natural female hormone) produced in the body. This decrease in estrogen can slow down or stop the growth of some breast cancers that need estrogen to grow. In addition, it is also useful in infertility whereby it increases the release of certain hormones to stimulate the release of eggs from the ovaries.
