Fareston is a nonsteroidal antiestrogen drug made up of toremifene. This medication can be purchased as its brand name of Fareston in 60mg. 

This medication is used to treat estrogen-receptor positive cancer, which is cancer that needs estrogen (a female hormone) in order to grow, in women who are post menopause. One of the most common types of cancer in females is breast cancer; this is the main condition Fareston is prescribed to treat. Breast cancer can become fatal if not treated during the early stages.

Fareston works to treat breast cancer by blocking the activity of estrogen in the breast tissue. Since breast cancer is estrogen-receptor positive, it needs estrogen to grow. By blocking the activity of estrogen, it is slowing or stopping the growth of cancer.
