For breast cancer treatment.Some breast cancers need the hormone oestrogen to grow. In women who have been through the menopause, the main source of oestrogen is through the change of sex hormones called androgens into oestrogen. An enzyme called 'aromatase' is needed for this change to occur. Letrozole works by inhibiting (or blocking) this enzyme. This reduces the amount of oestrogen in your body, which slows the growth of the cancer cells.

For infertility treatment. Letrozole is a recent addition to the drugs being used for fertility treatment. Fertility drugs are used often in infertility treatments. There are two situations in which fertility drugs may be useful. First, these drugs can be used to induce an egg to develop and be released in women who are not ovulating on their own. This is known as ovulation induction. Fertility drugs can also be used to increase the chances of pregnancy in women who are already ovulating. This is known as superovulation.

For athletics and bodybuilding. In athletics and bodybuilding, it is used as an ancillary compound within anabolic steroid cycles for its estrogen reducing properties, and has the additional benefit of modestly increasing testosterone levels. Many anabolic steroids aromatize (convert to estrogen via the aromatase enzyme), a process that is responsible for many of the undesirable side effects which accompany anabolic steroid use such as acne, gynecomastia, water-retention, etc.
